Macramé. Macramé is a form of textile produced using knotting (rather than weaving or knitting) techniques.The primary knots of macramé are the square (or reef knot) and forms of "hitching": various combinations of half hitches. It was long crafted by sailors, especially in elaborate or ornamental knotting forms, to cover anything from knife handles to bottles to parts of ships.Cavandoli macramé is one variety that is used to form geometric and free-form patterns like weaving. The Cavandoli style is done mainly in a single knot, the double half-hitch knot. Reverse half hitches are sometimes used to maintain balance when working left.

Macramé. and right halves of a balanced piece.Leather or fabric belts are another accessory often created via macramé techniques. Most friendship bracelets exchanged among schoolchildren and teens are created using this method. Vendors at theme parks, malls, seasonal fairs and other public places may sell macramé jewelry or decoration as well.## History.One of the earliest recorded uses of macramé-style knots as decoration appeared in the carvings of the Babylonians and Assyrians. Fringe-like plaiting and braiding adorned the costumes of the time and were captured in their stone statuary.Arab weavers knotted excess thread along the edges of hand-loomed fabrics such as towels,.

Macramé. shawls, and veils into decorative fringes. The word "macramé" is derived from the Arabic "macramia" (), believed to mean "striped towel", "ornamental fringe" or "embroidered veil". Another school of thought indicates that it comes from Turkish "makrama", "napkin" or "towel". The decorative fringes also helped to keep flies off camels and horses in northern Africa.The Moorish conquest took the craft to Spain, then Italy, especially in the region of Liguria, then it spread through Europe. In England, it was introduced at the court of Mary II in the late 17th century. Queen Mary taught it to her ladies-in-waiting.Macramé was most.

Macramé. popular in the Victorian era. It adorned most homes in items such as tablecloths, bedspreads and curtains. The popular "Sylvia's Book of Macramé Lace" (1882) showed how "to work rich trimmings for black and coloured costumes, both for home wear, garden parties, seaside ramblings, and balls—fairylike adornments for household and underlinens ...".It was a specialty in Genoa, and was popular in the 19th century. There, "Its roots were in a 16th-century technique of knotting lace known as "punto a groppo"" Sailors made macramé objects while not busy at sea, and sold or bartered them when they landed. Nineteenth-century British and.

Macramé. American sailors made hammocks, bell fringes, and belts from macramé. They called the process "square knotting" after the knot they used most often. Sailors also called macramé "McNamara's lace".Macramé's popularity faded, but resurged in the 1970s for making wall hangings, clothing accessories, small jean shorts, bedspreads, tablecloths, draperies, plant hangers and other furnishings. Macramé jewelry became popular in America. Using mainly square knots and granny knots, this jewelry often features handmade glass beads and natural elements such as bone and shell. Necklaces, anklets and bracelets have become popular forms of macramé jewelry. By the early 1980s, macramé again began to.

Macramé. fall out of fashion, only to be revived by millennials.## Materials and process.Materials used in macramé include cords made of cotton twine, linen, hemp, jute, leather or yarn. Cords are identified by construction, such as a 3-ply cord, made of three lengths of fibre twisted together. Jewelry is often made in combination of both the knots and various beads (of glass, wood, and so on), pendants or shells. Sometimes 'found' focal points are used for necklaces, such as rings or gemstones, either wire-wrapped to allow for securing or captured in a net-like array of intertwining overhand knots. A knotting board.

Macramé. is often used to mount the cords for macramé work. Cords may be held in place using a C-clamp, straight pins, T-pins, U-pins, or upholstery pins.For larger decorative pieces, such as wall hangings or window coverings, a work of macramé might be started out on a wooden or metal dowel, allowing for a spread of dozens of cords that are easy to manipulate. For smaller projects, push-pin boards are available specifically for macramé, although a simple corkboard works adequately. Many craft stores offer beginners' kits, work boards, beads and materials ranging in price for the casual hobbyist or ambitious crafter.

Aurochs. Europe to the Holstein interglacial. As indicated by fossil remains in Northern Europe, it reached Denmark and southern Sweden during the Holocene. The aurochs declined during the late Holocene due to habitat loss and hunting, and became extinct when the last individual died in 1627 in Jaktorów forest in Poland.The aurochs is depicted in Paleolithic cave paintings, Neolithic petroglyphs, Ancient Egyptian reliefs and Bronze Age figurines. It symbolised power, sexual potency and prowess in religions of the ancient Near East. Its horns were used in votive offerings, as trophies and drinking horns.Two aurochs domestication events occurred during the Neolithic Revolution.

Aurochs. in 1627 from natural causes.## Behaviour and ecology.Aurochs formed small herds mainly in winter, but lived singly or in smaller groups during the summer. If aurochs had social behaviour similar to their descendants, social status was gained through displays and fights, in which both cows and bulls engaged. With its hypsodont jaw, the aurochs was probably a grazer, with a food selection very similar to domesticated cattle feeding on grass, twigs and acorns.Mating season was in September, and calves were born in spring. The bulls had severe fights, and evidence from the Jaktorów forest shows these could lead to death.

Elephant. tall. As with other megaherbivores, including the extinct sauropod dinosaurs, the large size of elephants likely developed to allow them to survive on vegetation with low nutritional value. Their limbs grew longer and the feet shorter and broader. The feet were originally plantigrade and developed into a digitigrade stance with cushion pads and the sesamoid bone providing support. Early proboscideans developed longer mandibles and smaller craniums while more derived ones developed shorter mandibles, which shifted the head's centre of gravity. The skull grew larger, especially the cranium, while the neck shortened to provide better support for the skull. The increase.

Elephant. in size led to the development and elongation of the mobile trunk to provide reach. The number of premolars, incisors and canines decreased.The cheek teeth (molars and premolars) of proboscideans became larger and more specialized, especially after elephants started to switch from C3-plants to C4-grasses, which caused their teeth to undergo a three-fold increase in teeth height as well as substantial multiplication of lamellae after about five million years ago. Only in the last million years or so did they return to a diet mainly consisting of C3 trees and shrubs. The upper second incisors grew into tusks, which varied.

Elephant. gait similar to running. In walking, the legs act as pendulums, with the hips and shoulders rising and falling while the foot is planted on the ground. With no "aerial phase", the fast gait does not meet all the criteria of running, although the elephant uses its legs much like other running animals, with the hips and shoulders falling and then rising while the feet are on the ground. Fast-moving elephants appear to 'run' with their front legs, but 'walk' with their hind legs and can reach a top speed of 25 (km/h). At this speed, most other quadrupeds are.

Elephant. impede dehydration and improve thermal regulation over a long period of time.## Behaviour and life history.## Ecology and activities.The African bush elephant can be found in habitats as diverse as dry savannahs, deserts, marshes, and lake shores, and in elevations from sea level to mountains above the snow line. Forest elephants mainly live in equatorial forests but will enter gallery forests and ecotones between forests and savannahs. Asian elephants prefer areas with a mix of grasses, low woody plants, and trees, primarily inhabiting dry thorn-scrub forests in southern India and Sri Lanka and evergreen forests in Malaya. Elephants are herbivorous.


Question: What equipment or engine is used by this item to provide power?

Electric motor. An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators.Electric.

Electric motor. braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.Electric motors produce linear or rotary force (torque) intended to propel some external mechanism, such as a fan or an elevator. An electric motor is generally designed for continuous rotation, or for linear movement over a significant distance compared to its size. Magnetic solenoids are also transducers that convert electrical power to mechanical motion, but can produce motion over only a limited distance.## History.## Early motors.Before modern electromagnetic motors, experimental motors that worked by electrostatic force.

Electric motor. persistent electric currents. Hans Christian Ørsted discovered in 1820 that an electric current creates a magnetic field, which can exert a force on a magnet. It only took a few weeks for André-Marie Ampère to develop the first formulation of the electromagnetic interaction and present the Ampère's force law, that described the production of mechanical force by the interaction of an electric current and a magnetic field. The first demonstration of the effect with a rotary motion was given by Michael Faraday on 3 September 1821 in the basement of the Royal Institution. A free-hanging wire was dipped into a.

Electric motor. pool of mercury, on which a permanent magnet (PM) was placed. When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire. Faraday published the results of his discovery in the "Quarterly Journal of Science", and sent copies of his paper along with pocket-sized models of his device to colleagues around the world so they could also witness the phenomenon of electromagnetic rotations. This motor is often demonstrated in physics experiments, substituting brine for (toxic) mercury. Barlow's wheel was an early refinement.

Electric motor. to this Faraday demonstration, although these and similar homopolar motors remained unsuited to practical application until late in the century.In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for teaching, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced.

Electric motor. then higher performance.In 1855, Jedlik built a device using similar principles to those used in his electromagnetic self-rotors that was capable of useful work. He built a model electric vehicle that same year.A major turning point came in 1864, when Antonio Pacinotti first described the ring armature (although initially conceived in a DC generator, i.e. a dynamo). This featured symmetrically-grouped coils closed upon themselves and connected to the bars of a commutator, the brushes of which delivered practically non-fluctuating current. The first commercially successful DC motors followed the developments by Zénobe Gramme who, in 1871, reinvented Pacinotti's design and adopted.

Electric motor. from such tasks as handling grain or pumping water. Household uses (like in washing machines, dishwashers, fans, air conditioners and refrigerators (replacing ice boxes)) of electric motors reduced heavy labor in the home and made higher standards of convenience, comfort and safety possible. Today, electric motors consume more than half of the electric energy produced in the US.## AC motors.In 1824, French physicist François Arago formulated the existence of rotating magnetic fields, termed Arago's rotations, which, by manually turning switches on and off, Walter Baily demonstrated in 1879 as in effect the first primitive induction motor. In the 1880s many.

Electric motor. stator, which does not. It also includes two electrical parts, a set of magnets and an armature, one of which is attached to the rotor and the other to the stator, together forming a magnetic circuit: Field magnets - The magnets create a magnetic field that passes through the armature. These can be electromagnets or permanent magnets. The field magnet is usually on the stator and the armature on the rotor, but in some types of motor these are reversed.## Bearings.The rotor is supported by bearings, which allow the rotor to turn on its axis. The bearings are in turn.

Electric motor. supported by the motor housing.## Rotor.The rotor is the moving part that delivers the mechanical power. The rotor typically holds conductors that carry currents, which the magnetic field of the stator exerts force on to turn the shaft. Alternatively, some rotors carry permanent magnets, and the stator holds the conductors. Permanent magnets offer high efficiency over a larger operating speed and power range.An air gap between the stator and rotor allows it to turn. The width of the gap has a significant effect on the motor's electrical characteristics. It is generally made as small as possible, as a large gap.

Electric motor. weakens performance. It is the main source of the low power factor at which motors operate. The magnetizing current increases and the power factor decreases with the air gap, so narrow gaps are better. Conversely, gaps that are too small may pose mechanical problems in addition to noise and losses.The motor shaft extends through the bearings to the outside of the motor, where the load is applied. Because the forces of the load are exerted beyond the outermost bearing, the load is said to be overhung.## Stator.The stator surrounds the rotor, and usually holds field magnets, which are either electromagnets.

Electric motor. consisting of wire windings around a ferromagnetic iron core or permanent magnets. These create a magnetic field that passes through the rotor armature, exerting force on the windings. The stator core is made up of many thin metal sheets that are insulated from each other, called laminations. Laminations are used to reduce energy losses that would result if a solid core were used. Resin-packed motors, used in washing machines and air conditioners, use the damping properties of resin (plastic) to reduce noise and vibration. These motors encapsulate the stator in plastic.## Armature.The armature consists of wire windings on a ferromagnetic.

Electric motor. core. Electric current passing through the wire causes the magnetic field from the field magnet to exert a force (Lorentz force) on it, turning the rotor, which delivers the mechanical output. Windings are wires that are laid in coils, usually wrapped around a laminated, soft, iron, ferromagnetic core so as to form magnetic poles when energized with current.Electric machines come in salient- and nonsalient-pole configurations. In a salient-pole motor the ferromagnetic cores on the rotor and stator have projections called poles facing each other, with a wire winding around each pole below the pole face, which become north or south.

Electric motor. poles of the magnetic field when current flows through the wire. In a nonsalient-pole (or distributed field or round-rotor) motor, the ferromagnetic core is a smooth cylinder, with the windings distributed evenly in slots about the circumference. Supplying alternating current in the windings creates poles in the core that rotate continuously. A shaded-pole motor has a winding around part of the pole that delays the phase of the magnetic field for that pole.## Commutator.A commutator is a rotary electrical switch that supplies current to the rotor. It periodically reverses the flow of current in the rotor windings as the shaft.

Electric motor. each rotor winding would reverse with each half turn, so the rotor would stop. Commutators are inefficient and commutated motors have been mostly replaced by brushless direct current motors, permanent magnet motors, and induction motors.## Motor supply and control.## Motor supply.A DC motor is usually supplied through a split ring commutator as described above. AC motors' commutation can be achieved using either a slip ring commutator or external commutation. It can be fixed-speed or variable-speed control type, and can be synchronous or asynchronous. Universal motors can run on either AC or DC.## Motor control.DC motors can be operated at variable.

Electric motor. speeds by adjusting the voltage applied to the terminals or by using pulse-width modulation (PWM).AC motors operated at a fixed speed are generally powered directly from the grid or through motor soft starters.AC motors operated at variable speeds are powered with various power inverter, variable-frequency drive or electronic commutator technologies.The term electronic commutator is usually associated with self-commutated brushless DC motor and switched reluctance motor applications.## Types.Electric motors operate on one of three physical principles: magnetism, electrostatics and piezoelectricity.In magnetic motors, magnetic fields are formed in both the rotor and the stator. The product between these two fields gives rise.

Electric motor. to a force, and thus a torque on the motor shaft. One, or both, of these fields must change with the rotation of the rotor. This is done by switching the poles on and off at the right time, or varying the strength of the pole.The main types are DC motors and AC motors, with the latter replacing the former. AC electric motors are either asynchronous or synchronous.Once started, a synchronous motor requires synchrony with the moving magnetic field's speed for all normal torque conditions.In synchronous machines, the magnetic field must be provided by means other than induction, such as.

Electric motor. from separately excited windings or permanent magnets.A fractional-horsepower motor either has a rating below about 1 horsepower (0.746 kW), or is manufactured with a standard-frame size smaller than a standard 1 HP motor. Many household and industrial motors are in the fractional-horsepower class.Notes: Rotation is independent of the frequency of the AC voltage. Rotation is equal to synchronous speed (motor-stator-field speed). In SCIM, fixed-speed operation rotation is equal to synchronous speed, less slip speed. In non-slip energy-recovery systems, WRIM is usually used for motor-starting but can be used to vary load speed. Variable-speed operation. Whereas induction- and synchronous-motor drives are.

Electric motor. typically with either six-step or sinusoidal-waveform output, BLDC-motor drives are usually with trapezoidal-current waveform; the behavior of both sinusoidal and trapezoidal PM machines is, however, identical in terms of their fundamental aspects. In variable-speed operation, WRIM is used in slip-energy recovery and double-fed induction-machine applications. A cage winding is a shorted-circuited squirrel-cage rotor, a wound winding is connected externally through slip rings. Mostly single-phase with some three-phase.Abbreviations: BLAC – Brushless AC BLDC – Brushless DC BLDM – Brushless DC motor EC – Electronic commutator PM – Permanent magnet IPMSM – Interior permanent-magnet synchronous motor PMSM – Permanent magnet synchronous motor.

Electric motor. "RLA – rated-load amps".## Self-commutated motor.## Brushed DC motor.Most DC motors are small permanent magnet (PM) types. They contain a brushed internal mechanical commutation to reverse motor windings' current in synchronism with rotation.## Electrically excited DC motor.A commutated DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator. Thus, every brushed DC motor has AC flowing through its windings. Current flows through one or more pairs of brushes that touch the commutator; the brushes connect an external source of electric power to the rotating armature.The rotating armature.

Electric motor. consists of one or more wire coils wound around a laminated, magnetically "soft" ferromagnetic core. Current from the brushes flows through the commutator and one winding of the armature, making it a temporary magnet (an electromagnet). The magnetic field produced interacts with a stationary magnetic field produced by either PMs or another winding (a field coil), as part of the motor frame. The force between the two magnetic fields rotates the shaft. The commutator switches power to the coils as the rotor turns, keeping the poles from ever fully aligning with the magnetic poles of the stator field, so that.

Electric motor. – A set of windings that produces a magnetic field. Commutation: A mechanical technique in which rectification can be achieved, or from which DC can be derived.The five types of brushed DC motor are: Shunt-wound Series-wound Compound (two configurations): Cumulative compound Differentially compounded Permanent magnet (not shown) Separately excited (not shown).## Permanent magnet.A permanent magnet (PM) motor does not have a field winding on the stator frame, relying instead on PMs to provide the magnetic field. Compensating windings in series with the armature may be used on large motors to improve commutation under load. This field is fixed and cannot.

Electric motor. be adjusted for speed control. PM fields (stators) are convenient in miniature motors to eliminate the power consumption of the field winding. Most larger DC motors are of the "dynamo" type, which have stator windings. Historically, PMs could not be made to retain high flux if they were disassembled; field windings were more practical to obtain the needed flux. However, large PMs are costly, as well as dangerous and difficult to assemble; this favors wound fields for large machines.To minimize overall weight and size, miniature PM motors may use high energy magnets made with neodymium; most are neodymium-iron-boron alloy. With.

Electric motor. their higher flux density, electric machines with high-energy PMs are at least competitive with all optimally designed singly-fed synchronous and induction electric machines. Miniature motors resemble the structure in the illustration, except that they have at least three rotor poles (to ensure starting, regardless of rotor position) and their outer housing is a steel tube that magnetically links the exteriors of the curved field magnets.## Electronic commutator (EC).## Brushless DC.Some of the problems of the brushed DC motor are eliminated in the BLDC design. In this motor, the mechanical "rotating switch" or commutator is replaced by an external electronic switch.

Electric motor. synchronised to the rotor's position. BLDC motors are typically 85%+ efficient, reaching up to 96.5%, while brushed DC motors are typically 75–80% efficient.The BLDC motor's characteristic trapezoidal counter-electromotive force (CEMF) waveform is derived partly from the stator windings being evenly distributed, and partly from the placement of the rotor's permanent magnets. Also known as electronically commutated DC or inside-out DC motors, the stator windings of trapezoidal BLDC motors can be single-phase, two-phase or three-phase and use Hall effect sensors mounted on their windings for rotor position sensing and low cost closed-loop commutator control.BLDC motors are commonly used where precise speed.

Electric motor. motors are usually used in small equipment such as computers and are generally used in fans to remove heat. They make little noise, which is an advantage in equipment that is affected by vibrations.Modern BLDC motors range in power from a fraction of a watt to many kilowatts. Larger BLDC motors rated up to about 100 kW are used in electric vehicles. They also find use in electric model aircraft.## Switched reluctance motor.The switched reluctance motor (SRM) has no brushes or permanent magnets, and the rotor has no electric currents. Torque comes from a slight misalignment of poles on the.

Electric motor. rotor with poles on the stator. The rotor aligns itself with the magnetic field of the stator, while the stator field windings are sequentially energized to rotate the stator field.The magnetic flux created by the field windings follows the path of least magnetic sending the flux through rotor poles that are closest to the energized poles of the stator, thereby magnetizing those poles of the rotor and creating torque. As the rotor turns, different windings are energized, keeping the rotor turning.SRMs are used in some appliances and vehicles.## Universal AC/DC motor.A commutated, electrically excited, series or parallel wound motor is.

Electric motor. referred to as a universal motor because it can be designed to operate on either AC or DC power. A universal motor can operate well on AC because the current in both the field and the armature coils (and hence the resultant magnetic fields) synchronously reverse polarity, and hence the resulting mechanical force occurs in a constant direction of rotation.Operating at normal power line frequencies, universal motors are often used in sub-kilowatt applications. Universal motors formed the basis of the traditional railway traction motor in electric railways. In this application, using AC power on a motor designed to run on.

Electric motor. DC would experience efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron. They are now rarely used.An advantage is that AC power may be used on motors that specifically have high starting torque and compact design if high running speeds are used. By contrast, maintenance is higher and lifetimes are shortened. Such motors are used in devices that are not heavily used, and have high starting-torque demands. Multiple taps on the field coil provide (imprecise) stepped speed control. Household blenders that advertise many speeds.

Electric motor. an asynchronous AC motor where power is transferred to the rotor by electromagnetic induction, much like transformer action. An induction motor resembles a rotating transformer, because the stator (stationary part) is essentially the primary side of the transformer and the rotor (rotating part) is the secondary side. Polyphase induction motors are widely used in industry.## Cage and wound rotor.Induction motors may be divided into Squirrel Cage Induction Motors (SCIM) and Wound Rotor Induction Motors (WRIM). SCIMs have a heavy winding made up of solid bars, usually aluminum or copper, electrically connected by rings at the ends of the rotor. The.

Electric motor. bars and rings as a whole are much like an animal's rotating exercise cage.Currents induced into this winding provide the rotor magnetic field. The shape of the rotor bars determines the speed-torque characteristics. At low speeds, the current induced in the squirrel cage is nearly at line frequency and tends to stay in the outer parts of the cage. As the motor accelerates, the slip frequency becomes lower, and more current reaches the interior. By shaping the bars to change the resistance of the winding portions in the interior and outer parts of the cage, a variable resistance is effectively.

Electric motor. steering wheels.Another common application is to control the throttle of an internal combustion engine with an electronic governor. The motor works against a return spring to move the throttle in accord with the governor output. The latter monitors engine speed by counting electrical pulses from the ignition system or from a magnetic pickup and depending on the speed, makes small adjustments to the amount of current. If the engine slows down relative to the desired speed, the current increases, producing more torque, pulling against the return spring and opening the throttle. Should the engine run too fast, the governor reduces.

Electric motor. the current, allowing the return spring to pull back and reduce the throttle.## Synchronous motor.A synchronous electric motor is an AC motor. It includes a rotor spinning with coils passing magnets at the same frequency as the AC and produces a magnetic field to drive it. It has zero slip under typical operating conditions. By contrast induction motors must slip to produce torque. One type of synchronous motor is like an induction motor except that the rotor is excited by a DC field. Slip rings and brushes conduct current to the rotor. The rotor poles connect to each other and.

Electric motor. when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a permanent magnet synchronous motor. The rotor material, like that of a common nail, stays magnetized, but can be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.Low-power synchronous timing motors (such as those for traditional electric clocks) may have multi-pole permanent magnet external cup rotors, and use shading coils to provide starting torque. "Telechron" clock motors have shaded poles for starting torque, and a two-spoke ring rotor that performs like a discrete.

Electric motor. allows for a smaller electronic converter but the cost of the rotor winding and slip rings may offset the saving in the power electronics components. Difficulties affect controlling speed near synchronous speed limit applications.## Special magnetic motors.## Rotary.## Ironless or coreless rotor motor.The coreless or ironless DC motor is a specialized permanent magnet DC motor. Optimized for rapid acceleration, the rotor is constructed without an iron core. The rotor can take the form of a winding-filled cylinder, or a self-supporting structure comprising only wire and bonding material. The rotor can fit inside the stator magnets; a magnetically soft stationary cylinder.

Electric motor. inside the rotor provides a return path for the stator magnetic flux. A second arrangement has the rotor winding basket surrounding the stator magnets. In that design, the rotor fits inside a magnetically soft cylinder that can serve as the motor housing, and provides a return path for the flux.Because the rotor is much lower mass than a conventional rotor, it can accelerate much more rapidly, often achieving a mechanical time constant under one millisecond. This is especially true if the windings use aluminum rather than (heavier) copper. The rotor has no metal mass to act as a heat sink;.

Electric motor. even small motors must be cooled. Overheating can be an issue for these designs.The vibrating alert of cellular phones can be generated by cylindrical permanent-magnet motors, or disc-shaped types that have a thin multipolar disc field magnet, and an intentionally unbalanced molded-plastic rotor structure with two bonded coreless coils. Metal brushes and a flat commutator switch power to the rotor coils.Related limited-travel actuators have no core and a bonded coil placed between the poles of high-flux thin permanent magnets. These are the fast head positioners for rigid-disk ("hard disk") drives. Although the contemporary design differs considerably from that of loudspeakers,.

Electric motor. it is still loosely (and incorrectly) referred to as a "voice coil" structure, because some earlier rigid-disk-drive heads moved in straight lines, and had a drive structure much like that of a loudspeaker.## Pancake or axial rotor motor.The printed armature or pancake motor has windings shaped as a disc running between arrays of high-flux magnets. The magnets are arranged in a circle facing the rotor spaced to form an axial air gap. This design is commonly known as the pancake motor because of its flat profile.The armature (originally formed on a printed circuit board) is made from punched copper sheets.

Electric motor. with 180 (C), Class H rating.The unique advantage of ironless DC motors is the absence of cogging (torque variations caused by changing attraction between the iron and the magnets). Parasitic eddy currents cannot form in the rotor as it is totally ironless, although iron rotors are laminated. This can greatly improve efficiency, but variable-speed controllers must use a higher switching rate (>40 kHz) or DC because of decreased electromagnetic induction.These motors were invented to drive the capstan(s) of magnetic tape drives, where minimal time to reach operating speed and minimal stopping distance were critical. Pancake motors are widely used in.

Electric motor. high-performance servo-controlled systems, robotic systems, industrial automation and medical devices. Due to the variety of constructions now available, the technology is used in applications from high temperature military to low cost pump and basic servos.Another approach (Magnax) is to use a single stator sandwiched between two rotors. One such design has produced peak power of 15 kW/kg, sustained power around 7.5 kW/kg. This yokeless axial flux motor offers a shorter flux path, keeping the magnets further from the axis. The design allows zero winding overhang; 100 percent of the windings are active. This is enhanced with the use of rectangular-crosssection.

Electric motor. copper wire. The motors can be stacked to work in parallel. Instabilities are minimized by ensuring that the two rotor discs put equal and opposing forces onto the stator disc. The rotors are connected directly to one another via a shaft ring, cancelling out the magnetic forces.Magnax motors range in size from 0.15-5.4 (m) in diameter.## Servo motor.A servo motor is a motor that is used within a position-control or speed-control feedback system. Servomotors are used in applications such as machine tools, pen plotters, and other process systems. Motors intended for use in a servomechanism must have predictable characteristics for.

Electric motor. speed, torque, and power. The speed/torque curve is important and is high ratio for a servo motor. Dynamic response characteristics such as winding inductance and rotor inertia are important; these factors limit performance. Large, powerful, but slow-responding servo loops may use conventional AC or DC motors and drive systems with position or speed feedback. As dynamic response requirements increase, more specialized motor designs such as coreless motors are used. AC motors' superior power density and acceleration characteristics tends to favor permanent magnet synchronous, BLDC, induction, and SRM drive approaches.A servo system differs from some stepper motor applications in that position.

Electric motor. feedback is continuous while the motor is running. A stepper system inherently operates open-loop—relying on the motor not to "miss steps" for short term accuracy—with any feedback such as a "home" switch or position encoder external to the motor system.## Stepper motor.Stepper motors are typically used to provide precise rotations. An internal rotor containing permanent magnets or a magnetically soft rotor with salient poles is controlled by a set of electronically switched external magnets. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in.

Electric motor. turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, the stepper motor may not rotate continuously; instead, it moves in steps—starting and then stopping—advancing from one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down at any time.Simple stepper motor drivers entirely energize or entirely de-energize the field windings, leading the rotor to "cog" to a limited number of positions. Microstepping drivers can proportionally.

Electric motor. made them uncompetitive—thus newer hard disk drives use voice coil-based head actuator systems. (The term "voice coil" in this connection is historic; it refers to the structure in a cone-type loudspeaker.)Stepper motors are often used in computer printers, optical scanners, and digital photocopiers to move the active element, the print head carriage (inkjet printers), and the platen or feed rollers.So-called quartz analog wristwatches contain the smallest commonplace stepping motors; they have one coil, draw little power, and have a permanent magnet rotor. The same kind of motor drives battery-powered quartz clocks. Some of these watches, such as chronographs, contain more.

Electric motor. 1978 era HP 7225A pen plotter used two linear stepper motors to move the pen along the X and Y axes.## Electromagnetism.## Force and torque.An electric motor converts electrical energy to mechanical energy through the force between two opposed magnetic fields. At least one of the two magnetic fields must be created by an electromagnet through the magnetic field caused by an electrical current.The force between a current formula_1 in a conductor of length formula_2 perpendicular to a magnetic field formula_3 may be calculated using the Lorentz force law: formula_4Note: X denotes vector cross product. The most general approaches to.

Electric motor. resistance Ir2 – square of current induced in the rotor s – motor slip; i.e., difference between synchronous speed and slip speed, which provides the relative movement needed for current induction in the rotor.## Back EMF.The movement of armature windings of a direct-current or universal motor through a magnetic field, induce a voltage in them. This voltage tends to oppose the motor supply voltage and so is called "back electromotive force (EMF)". The voltage is proportional to the running speed of the motor. The back EMF of the motor, plus the voltage drop across the winding internal resistance and brushes,.

Electric motor. enacted legislation to encourage the manufacture and use of higher-efficiency motors. Electric motors have efficiencies ranging from at least 15% for shaded pole motors, up to 98% for permanent magnet motors, with efficiency also dependent on load. Peak efficiency is usually at 75% of the rated load. So (as an example) a 10 HP motor is most efficient when driving a load that requires 7.5 HP. Efficiency also depends on motor size; larger motors tend to be more efficient. Some motors can not operate continually for more than a specified period of time (e.g. for more than an hour per.

Electric motor. run)## Goodness factor.Eric Laithwaite proposed a metric to determine the 'goodness' of an electric motor: formula_21Where: formula_22 is the goodness factor (factors above 1 are likely to be efficient) formula_23 are the cross sectional areas of the magnetic and electric circuit formula_24 are the lengths of the magnetic and electric circuits formula_25 is the permeability of the core formula_20 is the angular frequency the motor is driven atFrom this, he showed that the most efficient motors are likely to have relatively large magnetic poles. However, the equation only directly relates to non PM motors.## Performance parameters.## Torque.Electromagnetic motors derive torque.

Electric motor. from the vector product of the interacting fields. Calculating torque requires knowledge of the fields in the air gap. Once these have been established, the torque is the integral of all the force vectors multiplied by the vector's radius. The current flowing in the winding produces the fields. For a motor using a magnetic material the field is not proportional to the current.A figure relating the current to the torque can inform motor selection. The maximum torque for a motor depends on the maximum current, absent thermal considerations.When optimally designed within a given core saturation constraint and for a given.

Electric motor. active current (i.e., torque current), voltage, pole-pair number, excitation frequency (i.e., synchronous speed), and air-gap flux density, all categories of electric motors/generators exhibit virtually the same maximum continuous shaft torque (i.e., operating torque) within a given air-gap area with winding slots and back-iron depth, which determines the physical size of electromagnetic core. Some applications require bursts of torque beyond the maximum, such as bursts to accelerate an electric vehicle from standstill. Always limited by magnetic core saturation or safe operating temperature rise and voltage, the capacity for torque bursts beyond the maximum differs significantly across motor/generator types.Electric machines without a.

Electric motor. transformer circuit topology, such as that of WRSMs or PMSMs, cannot provide torque bursts without saturating the magnetic core. At that point, additional current cannot increase torque. Furthermore, the permanent magnet assembly of PMSMs can be irreparably damaged.Electric machines with a transformer circuit topology, such as induction machines, induction doubly-fed electric machines, and induction or synchronous wound-rotor doubly-fed (WRDF) machines, permit torque bursts because the EMF-induced active current on either side of the transformer oppose each other and thus contribute nothing to the transformer coupled magnetic core flux density, avoiding core saturation.Electric machines that rely on induction or asynchronous principles.

Electric motor. the air-gap area and the back-iron depth, which are determined by the power rating of the armature winding set, the speed of the machine, and the achievable air-gap flux density before core saturation. Despite the high coercivity of neodymium or samarium-cobalt permanent magnets, continuous torque density is virtually the same amongst electric machines with optimally designed armature winding sets. Continuous torque density relates to method of cooling and permissible operation period before destruction by overheating of windings or permanent magnet damage.Other sources state that various e-machine topologies have differing torque density. One source shows the following:where—specific torque density is normalized.

Electric motor. to 1.0 for the surface permanent magnet (SPM)—brushless ac, 180° current conduction.Torque density is approximately four times greater for liquid cooled motors, compared to those which are air cooled.A source comparing direct current, induction motors (IM), PMSM and SRM showed:Another source notes that PMSM up to 1 MW have considerably higher torque density than induction machines.## Continuous power density.The continuous power density is determined by the product of the continuous torque density and the constant torque speed range. Electric motors can achieve densities of up to 20KW/KG, meaning 20 Kilowatts of output power per kilogram.## Acoustic noise and vibrations.Acoustic noise.

Electric motor. and vibrations are usually classified in three sources: mechanical sources (e.g. due to bearings) aerodynamic sources (e.g. due to shaft-mounted fans) magnetic sources (e.g. due to magnetic forces such as Maxwell and magnetostriction forces acting on stator and rotor structures)The latter source, which can be responsible for the "whining noise" of electric motors, is called electromagnetically induced acoustic noise.## Standards.The following are major design, manufacturing, and testing standards covering electric motors: American Petroleum Institute: API 541 Form-Wound Squirrel Cage Induction Motors – 375 kW (500 Horsepower) and Larger American Petroleum Institute: API 546 Brushless Synchronous Machines – 500 kVA and.

Arch of Hadrian (Jerash). The Arch of Hadrian is an ancient Roman structure in Jerash, Jordan. It is an 11-metre high triple-arched gateway erected to honor the visit of Roman Emperor Hadrian to the city (then called Gerasa) in the winter of 129–130. The arch originally stood to almost 22 m and probably had wooden doors. It features some unconventional, possibly Nabataean, architectural features, such as acanthus bases. The columns are decorated with capitals at the bottom rather than the top. The monument served both as a commemorative arch and as an approach to Gerasa. The Arch's relative remoteness from the city walls points.

Dryocampa rubicunda. Dryocampa rubicunda, the rosy maple moth, is a small North American moth in the family Saturniidae, also known as the great silk moths. It was first described by Johan Christian Fabricius in 1793. The species is known for its wooly body and pink and yellow coloration, which varies from cream or white to bright pink or yellow. Males have bushier antennae than females, which allow them to sense female pheromones for mating.As the common name of the species implies, the preferred host trees are maple tree. Adult females lay their yellow ovular eggs in groups of 10 to 40 on.

Dryocampa rubicunda. the underside of maple leaves. The emerging caterpillars, also known as the greenstriped mapleworm, mainly feed on the leaves of their host maple trees, particularly red maple, silver maple, and sugar maple. Since the caterpillars eat the entire leaf blade, in dense populations, caterpillars have been known to defoliate trees, resulting in aesthetic rather than permanent damage. However, like all other Saturniid moths, the adult moths do not eat.## Description.The rosy maple moth is the smallest of the silk moths; males have a wingspan of 3.2 to 4.4 centimetres (1.25-1.75 in); females of 3.8 to 5 centimetres (1.5–2 in). The.

Dryocampa rubicunda. species can be identified by their unique, but varying, pink and yellow coloration. They have reddish-to-pink legs and antennae, yellow bodies and hindwings, and pink forewings with a triangular yellow band across the middle.## Geographic range.The rosy maple moth lives across the eastern United States and adjacent regions of Canada. Their northernmost range includes the southern regions of Canada, including Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island. Their range extends south along the Atlantic coast of North America to Dade County, Florida, and extends west from eastern Texas through Minnesota.## Habitat.The rosy maple moth can be found.

Dryocampa rubicunda. in temperate deciduous forests and nearby suburban areas and urban landscapes. Their common name derives from the fact that they can primarily be found on maple trees, including red maples ("Acer rubrum"), sugar maples ("Acer saccharum"), silver maples ("Acer saccharinum"), and box elder maples ("Acer negundo"). They can also be found on oak trees, particularly turkey oaks ("Quercus laevis"), especially when they are found dispersed among maple trees.## Home range and territoriality.Larvae hatch and live on the same tree through their development, then pupate in the soil beneath the same tree. The larvae primarily eat the underside of leaves, therefore.

Dryocampa rubicunda. preferentially staying in that location of their home tree. The adults do not eat, so they can have a sizeable home range.## Behavior.## Feeding.The rosy maple moths preferentially lay their eggs on maple trees, and sometimes nearby oak trees. Since the larvae remain on the same tree upon which they hatched, most larvae feed on the underside of maple leaves or oak leaves. In early instars, the larvae feed together in groups, but beginning in the third or fourth instar the caterpillars begin to feed individually. The larvae eat the entire leaf blade and are capable of consuming a few.

Dryocampa rubicunda. leaves each. Thus, large populations of greenstriped mapleworms are capable of defoliating trees. This damage is mostly harmless and the leaves will grow back. Adult rosy maple moths do not feed.## Parental care.## Oviposition.Female rosy maple moths lay their eggs one day after fertilization. During those 24 hours, the eggs are protected inside the body of the female. Besides this, rosy maple moths exhibit little parental care, as the female leaves after depositing her eggs. Females typically lay around 150 to 200 eggs in groups of 10 to 40 on the underside of leaves of maple trees and occasionally oak.

Dryocampa rubicunda. trees. Females typically only reproduce once, but in southern regions they can lay eggs up to three times. Egg laying typically occurs in the warmer months, with a peak in July, although precise timing depends on the region. In northern regions, one brood is laid between May and August. Further south, two broods are laid between April and September. In Florida, between March and October three broods are laid.## Social behavior.Caterpillars live and feed in groups until the fourth instar when they become solitary. Adult rosy maple moths are mostly solitary besides during mating.## Life cycle.Individual rosy maple moths typically.

Dryocampa rubicunda. live for about two to nine months. Between hatching and adulthood, the species undergoes five instars. For moths with longer life spans, much of this time is spent as a pupa over the winter months.## Eggs.Eggs are laid 24 hours after fertilization. The eggs are ovular and about 1.4 mm in diameter, with a thin smooth yellow shell. Eggs hatch after about ten days to two weeks. After hatching, a transparent egg shell is left behind.## Caterpillar.Rosy maple moth larvae are known as greenstriped mapleworms, and they undergo five instars prior to adulthood, during which their coloration and eating behavior.

Dryocampa rubicunda. changes. In early instars, the larvae have relatively large black heads and pale yellow-green bodies with faint green stripes. They have two large dark-green to black tubercles on the second thoracic segment and three rows of smaller spines, or setae, on each side of their body. The larvae undergo their first molt around 6–11 days after hatching, their second molt approximately 12 days after hatching, and their third molt around 19 days post hatching. In the next instars, the black head becomes smaller relative to the diameter of the body and the longitudinal stripes darken and become reddish. In later.

Dryocampa rubicunda. instars, the head becomes yellow, and in the final instar, becomes bright red. By the final instar, the body is yellow green with longitudinal stripes that range from white to green to black. The two prominent horns on the second thoracic segment are accompanied by two rows of short spines found along both sides of the body. At maturity, the caterpillars reach lengths of about 2 inches. Until the fourth instar, the larvae live and feed together, but in their final two instars they are solitary.## Pupa.After about a month, full-grown caterpillars crawl to the bottom of the host tree.

Dryocampa rubicunda. and pupate in shallow underground chambers. The pupae are very dark, elongated, and have small spines. The pupa ends in a small forked point. The pupal stage lasts at least two weeks and up to the whole winter. If the moths pupate over winter, the majority of their lives are spent in the pupal stage. When the imago (adult) ecloses, it has small wings which it has to pump full of fluid in order to expand them and allow for flight.## Adult.Adult rosy maple moths are distinguishable by their bright pink and yellow color, although exact coloration can vary significantly.

Dryocampa rubicunda. Both sexes have a wingspan of 32–55 mm. Their bodies are woolly, and typically yellow on the top and pink on the underside, but can range to cream or white. Their legs and antennae are also pink. The forewings can be yellow to white with varying amounts of pink along the edges. The "alba" subspecies, found in Missouri, is completely white or white with faint pink markings.## Predators.The predators of the rosy maple moth and larvae mostly consist of birds including blue jays, black-capped chickadees, and tufted titmice. The bright coloration of the wings may serve as a defense mechanism.

Dryocampa rubicunda. to trick predators into thinking they are poisonous and not edible. The colouration of this moth rather surprisingly acts as a form of camouflage, blending it in with maple seed cases.## Mating.Rosy maple moths exhibit sexual dimorphism, that is males and females have different appearances. In the case of the rosy maple moth, males have narrower and less rounded wings. Additionally, while females have simple antennae, males have bipectinate (comb-like on both sides) antennae to sense females' pheromones during mating. The moths become sexually mature at 2 to 9 months of age. Mating occurs at night, when females release pheromones.

Dryocampa rubicunda. to attract males. Fertilization occurs internally, and females lay their eggs 24 hours after mating. The moths are polygyandrous: females find a new male to mate with each time during breeding season when multiple broods are laid per season in warmer regions.## Thermoregulation.Adults become active in the warmer months of the year. In a study that compared "D. rubicunda" with "Actias luna", the prevalence of the rosy maple moth was found to vary with changes in temperature, with highest counts at the highest temperature, perhaps due to the tropical origin of the subfamily Ceratocampinae. Their small size, preventing more effective.

Dryocampa rubicunda. body temperature control, may also contribute to their preference for warm weather. Adult moths are generally nocturnal, preferentially flying throughout the first third of the night.

Wolf. habitat.Wolves occur across Eurasia and North America. However, deliberate human persecution because of livestock predation and fear of attacks on humans has reduced the wolf's range to about one-third of its historic range; the wolf is now extirpated (locally extinct) from much of its range in Western Europe, the United States and Mexico, and completely in Ireland, the United Kingdom, and Japan. In modern times, the wolf occurs mostly in wilderness and remote areas. The wolf can be found between sea level and 3000 (m). Wolves live in forests, inland wetlands, shrublands, grasslands (including Arctic tundra), pastures, deserts, and rocky.

Wolf. are nocturnal predators. During the winter, a pack will commence hunting in the twilight of early evening and will hunt all night, traveling tens of kilometres. Sometimes hunting large prey occurs during the day. During the summer, wolves generally tend to hunt individually, ambushing their prey and rarely giving pursuit.When hunting large gregarious prey, wolves will try to isolate an individual from its group. If successful, a wolf pack can bring down game that will feed it for days, but one error in judgement can lead to serious injury or death. Most large prey have developed defensive adaptations and behaviours.

Rhododendron maximum. Rhododendron maximum — its common names include great laurel, great rhododendron, rosebay rhododendron, American rhododendron and big rhododendron — is a species of "Rhododendron" native to the Appalachians of eastern North America, from Alabama north to coastal Nova Scotia.## Description."Rhododendron maximum" is an evergreen shrub growing to 4 (m), rarely 10 (m), tall. The leaves are 9 – 19 (cm) long and 2 – 4 (cm) broad. The flowers are 2.5-3 (cm) diameter, white, pink or pale purple, often with small greenish-yellow spots. The fruit is a dry capsule 15 – 20 (mm) long, containing numerous small seeds. The leaves.

Rhododendron maximum. can be poisonous. Leaves are sclerophyllous, simple, alternate, and oblong (10 to 30 cm long, 5 to 8 cm wide). It retains its waxy, deep-green leaves for up to 8 years, but once shed are slow to decompose. It produces large, showy, white to purple flowers each June and July.## Range.Rosebay rhododendron is the most frequently occurring and dominant species of "Rhododendron" in the southern Appalachian region, and occurs occasionally on mesic hill-slopes throughout the upper Piedmont Crescent of the Southeastern United States.## Ecology.Approximately 12,000 square miles in the southern Appalachians are occupied by this species where it dominates the.

Rhododendron maximum. understory. This species has historically been confined to riparian areas and other mesic sites but takes advantage of disturbed areas where it is present to advance onto sub-mesic sites. It prefers deep well-drained acid soils high in organic matter where it produces a thick, peat-like humus. It prefers low to medium light conditions for optimum carbon gain, and has a tremendous capacity for avoiding cavitation during freeze-thaw cycles. Where extensive overstory mortality has eliminated most of the overstory, this species forms a thick and continuous subcanopy known locally as ‘laurel slicks’ or ‘laurel hells’. Rosebay rhododendron is an important structural.

Rhododendron maximum. and functional component of southern Appalachian forest ecosystems. What isn't clear is whether or not we are in a period of advancement or retreat for this species. For example, on poorly drained sites on ridge or upper slope positions, large areas of rosebay rhododendron, particularly at the high elevations, have recently died out presumably due to the "Phytophthora" fungus, or due to recent prolonged periods of below-average precipitation. Yet, rosebay rhododendron now occupies sites that historically were free of evergreen understory. There are still important questions to be answered regarding this species to completely understand its role in forest understories.##.

Rhododendron maximum. Reproduction.Rosebay rhododendron is clonal. It is capable, however, of reproducing both vegetatively and sexually. It reproduces vegetatively through a process called ‘layering’ where it produces roots from above ground woody parts when in contact with the forest floor. The fruit is produced from showy flowers from March to August. The fruit is an oblong capsule that ripens in the fall, and splits along the sides soon after ripening to release large numbers of minute seed (approx. 400 per capsule). Microsite requirements for seed germination are relatively specific (e.g., high in organic matter such as rotting logs); hence, the majority of.

Rhododendron maximum. reproduction is vegetative resulting in a clonal distribution.## Growth and management.Seeds from rosebay rhododendron are minute and it is estimated that approximately 11 million are contained in 1 kg. Commercial seed production is generally from cultivated hybrids. Seeds from wild sources are not commonly sold commercially. Rosebay rhododendron is a slow-growing shrub and has a very high sprout potential. If mechanical removal is attempted in the case of forest management, extremely high densities are attained by this species in a matter of a few years. Prescribed fire has also been used to control this species but with limited success.## Benefits.Rosebay.

Rhododendron maximum. rhododendron is a striking and aesthetically pleasing feature of mesic southern Appalachian forests. It is one of the largest and hardiest rhododendrons grown commercially. Several cultivars with white to purple flowers have been selected for the horticultural trade. Where it occurs naturally, it produces a showy, white, pink, or light purple flower primarily in June, but occurs from March into August. Rosebay rhododendron maintains deep-green foliage year round. This species affords protection to steep watersheds and shelter for wildlife. The wood is very hard and is occasionally used for specialty wood products.## Detrimental effects.For all its prized qualities as a.

Rhododendron maximum. naturally occurring component of the landscape or as plantings in residential and commercial landscaping, rosebay rhododendron can have an inhibitory effect on regeneration of other plant species. There is some evidence to suggest that due to fire suppression and the absence of other cultural activities (i.e., mountain-land grazing), this species has advanced beyond the mesic forest sites into sub-mesic understories. The significance of this movement onto previously unoccupied sites centers around the impacts of rosebay rhododendron on plant succession and resource availability. Rosebay rhododendron is associated with reduced woody and herbaceous seedling abundance throughout its range, and hence poses a.

Rhododendron maximum. serious impediment to the production of wood products. The mechanism(s) by which rosebay rhododendron reduces seedling survival has been the subject of much debate. Possible sources of inhibition include allelopathy, competition for resources including light, physical and chemical attributes of the forest floor and soil, and interactions between some or all sources.## Alternate common names."R. maximum" has also been called:Great rhododendronLate rhododendronSummer rhododendronGreat laurelBigleaf laurelDeertongue laurelRose treeRose bayBayis## Symbolism."Rhododendron maximum" is the state flower of the U.S. state of West Virginia.

Cirsium vulgare. Cirsium vulgare, the spear thistle, bull thistle, or common thistle, is a species of the Asteraceae genus "Cirsium", native throughout most of Europe (north to 66°N, locally 68°N), Western Asia (east to the Yenisei Valley), and northwestern Africa (Atlas Mountains). It is also naturalised in North America, Africa, and Australia and is an invasive weed in some areas. It is the national flower of Scotland.The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand.

Cirsium vulgare. project which is supported by the UK Insect Pollinators Initiative. Marsh thistle, "Cirsium palustre", was ranked in first place while this thistle was ranked in sixth place. It also was a top producer of nectar sugar in another study in Britain, ranked third with a production per floral unit of (2300 ± 400 μg).## Description.It is a tall biennial or short-lived monocarpic thistle, forming a rosette of leaves and a taproot up to 70 cm long in the first year, and a flowering stem 1–1.5 m tall in the second (rarely third or fourth) year. It can grow up to.

Cirsium vulgare. 1.8 (m) tall. It sometimes will function as an annual, flowering in the first year. The stem is winged, with numerous longitudinal spine-tipped wings along its full length. The leaves are stoutly spined, grey-green, deeply lobed; the basal leaves grow up to 30 (cm) long, with smaller leaves on the upper part of the flower stem; the leaf lobes are spear-shaped (from which the English name derives). The inflorescence is 2.5–5 cm diameter, pink-purple, with all the florets of similar form (no division into disc and ray florets). The seeds are 5 mm long, with a downy pappus, which assists.

Cirsium vulgare. in wind dispersal. As in other species of "Cirsium" (but unlike species in the related genus "Carduus"), the pappus hairs are feathery with fine side hairs.## Ecology.Spear thistle is often a ruderal species, colonising bare disturbed ground, but also persists well on heavily grazed land as it is unpalatable to most grazing animals. Nitrogen-rich soils help increase its proliferation. The flowers are a rich nectar source used by numerous pollinating insects, including honey bees, wool-carder bees, and many butterflies. The seeds are eaten by goldfinches, linnets and greenfinches. The seeds are dispersed by wind, mud, water, and possibly also by.

Cirsium vulgare. ants; they do not show significant long-term dormancy, most germinating soon after dispersal and only a few lasting up to four years in the soil seed bank. Seed is also often spread by human activity such as hay bales.## Weed status.Spear thistle is designated an "injurious weed" under the UK Weeds Act 1959, and a noxious weed in Australia and in nine US states. Spread is only by seed, not by root fragments as in the related creeping thistle "C. arvense". It is best cleared from land by hoeing and deep cutting of the taproot before seeds mature; regular cultivation.

Cirsium vulgare. also prevents its establishment.Despite this label, the plant has beneficial qualities beyond its very high nectar production. It produces seeds eaten by the American goldfinch, down from seed pods that is used by those birds for nesting material, and serves as a host plant for the Painted lady butterfly. The monarch butterfly and other larger-sized butterflies can feed easily from the flowers due to their large size. Some farmers, due to its usefulness as part of the natural food chain, may find it useful to allow it to grow in beetle banks. The supports for pollinators and pest-eating birds could.

Cirsium vulgare. outweigh its drawbacks. In areas where it does not form monocultures it may also be welcome as a part of a meadow landscape.## Other names.Common names include bull thistle, Scots, Scottish, or Scotch thistle, and common thistle.## Uses.The stems can be peeled (removing their spiny surfaces) and then steamed or boiled. The tap roots can be eaten raw or cooked, but are only palatable on young thistles that have not yet flowered. The dried florets steeped in water are used in rural Italy for curdling goats' milk in preparation for making cheese.## In culture.The plant features in some Scottish ceremonies.
