Muskrat. The muskrat ("Ondatra zibethicus") is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands, and is a resource of food and fur for humans.Adult muskrats weigh 0.6 - 2 (kg), with a body length of 20 - 35 (cm). They are covered with short, thick fur of medium to dark brown color. Their long tails, covered with scales rather than hair, are their main means of.

Muskrat. and are their main means of propulsion. Their tail functions as a rudder, controlling the direction they swim in.## Distribution and ecology.Muskrats are found over most of Canada and the United States and a small part of northern Mexico. They were introduced to Europe in the beginning of the 20th century and have become an invasive species in northwestern Europe. They mostly inhabit wetlands, areas in or near saline and freshwater wetlands, rivers, lakes, or ponds. They are not found in Florida, where the round-tailed muskrat, or Florida water rat ("Neofiber alleni"), fills their ecological niche.Their populations naturally cycle; in.

Muskrat. been created by the construction of canals or irrigation channels (e.g., acequias), and the muskrat remains common and widespread. They are able to live alongside streams which contain the sulfurous water that drains away from coal mines. Fish and frogs perish in such streams, yet muskrats may thrive and occupy the wetlands. Muskrats also benefit from human persecution of some of their predators.The muskrat is classed as a "prohibited new organism" under New Zealand's Hazardous Substances and New Organisms Act 1996, preventing it from being imported into the country.The trematode "Metorchis conjunctus" can also infect muskrats.## Invasiveness status.In Europe, the.

Muskrat. muskrat has been included in the list of invasive alien species of Union concern (the Union list) since August 2, 2017. This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.## Behavior.Muskrats normally live in families consisting of a male and female and their young. During the spring, they often fight with other muskrats over territory and potential mates. Many are injured or killed in these fights. Muskrat families build nests to protect themselves and their young from cold and predators. In streams, ponds, or lakes,.

Muskrat. Muskrats were introduced at that time to Europe as a fur resource, and spread throughout northern Europe and Asia.In some European countries, such as Belgium, France, and the Netherlands, the muskrat is considered an invasive pest, as its burrowing damages the dikes and levees on which these low-lying countries depend for protection from flooding. In those countries, it is trapped, poisoned, and hunted to attempt to keep the population down. Muskrats also eat corn and other farm and garden crops growing near water bodies.Royal Canadian Mounted Police winter hats are made from muskrat fur. Everything Muskrat How Muskrat Created the.

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 motors can achieve densities of up to 20KW/KG, meaning 20 Kilowatts of output power per kilogram.## Acoustic noise and vibrations.Acoustic noise.

Kiwi (bird). Kiwi ( ) are flightless birds endemic to New Zealand of the genus Apteryx () and family Apterygidae (). Approximately the size of a domestic chicken, kiwi are by far the smallest living ratites (which also include ostriches, emus, rheas and cassowaries).DNA sequence comparisons have yielded the surprising conclusion that kiwi are much more closely related to the extinct Malagasy elephant birds than to the moa with which they shared New Zealand. There are five recognised species, four of which are currently listed as vulnerable, and one of which is near-threatened. All species have been negatively affected by historic deforestation,.

Kiwi (bird). icon of New Zealand, and the association is so strong that the term "Kiwi" is used internationally as the colloquial demonym for New Zealanders.## Etymology.The Māori language word is generally accepted to be "of imitative origin" from the call. However, some linguists derive the word from Proto-Nuclear Polynesian , which refers to "Numenius tahitiensis", the bristle-thighed curlew, a migratory bird that winters in the tropical Pacific islands. With its long decurved bill and brown body, the curlew resembles the kiwi. So when the first Polynesian settlers arrived, they may have applied the word kiwi to the new-found bird. The word.

Kiwi (bird). is usually uncapitalised when used for the birds. The plural is either the anglicised "kiwis" or, consistent with the Māori language, appearing as "kiwi" without an "‑s".The genus name "Apteryx" is derived from Ancient Greek 'without wing': (), 'without' or 'not'; (), 'wing'.## Taxonomy and systematics.Although it was long presumed that the kiwi was closely related to the other New Zealand ratites, the moa, recent DNA studies have identified its closest relative as the extinct elephant bird of Madagascar, and among extant ratites, the kiwi is more closely related to the emu and the cassowaries than to the moa.Research published.

Kiwi (bird). in 2013 on an extinct genus, "Proapteryx", known from the Miocene deposits of the Saint Bathans Fauna, found that it was smaller and probably capable of flight, supporting the hypothesis that the ancestor of the kiwi reached New Zealand independently from moas, which were already large and flightless by the time kiwi appeared.## Species.There are five known species of kiwi, with a number of subspecies.## Description.Their adaptation to a terrestrial life is extensive: like all the other ratites (ostrich, emu, rhea and cassowary), they have no keel on the sternum to anchor wing muscles. The vestigial wings are so small.

Kiwi (bird). an experiment, it was observed that one-third of a population of "A. rowi" in New Zealand under no environmental stress had ocular lesions in one or both eyes. The same experiment examined three specific specimens that showed complete blindness and found them to be in good physical standing outside of ocular abnormalities. A 2018 study revealed that the kiwi's closest relatives, the extinct elephant birds, also shared this trait despite their great size.Unlike virtually every other palaeognath, which are generally small-brained by bird standards, kiwi have proportionally large encephalisation quotients. Hemisphere proportions are even similar to those of parrots and.

Kiwi (bird). songbirds, though there is no evidence of similarly complex behaviour.## Behaviour and ecology.Before the arrival of humans in the 13th century or earlier, New Zealand's only endemic mammals were , and the ecological niches that in other parts of the world were filled by creatures as diverse as horses, wolves and mice were taken up by birds (and, to a lesser extent, reptiles, insects and gastropods).The kiwi's mostly nocturnal habits may be a result of habitat intrusion by predators, including humans. In areas of New Zealand where introduced predators have been removed, such as sanctuaries, kiwi are often seen in.

Kiwi (bird). of food. Two to three days before the egg is laid there is little space left inside the female for her stomach and she is forced to fast.It was believed that the large eggs were a trait of much larger moa-like ancestors, and that kiwis retained large eggs as an evolutionarily neutral trait as they became smaller. However, research in the early 2010s suggested that kiwis were descended from smaller flighted birds that flew to New Zealand and Madagascar, where they gave rise to kiwis and elephant birds. The large egg is instead thought to be an adaptation for precocity,.

Kiwi (bird). enabling kiwi chicks to hatch mobile and with yolk to sustain them for two and half weeks. The large eggs would be safe in New Zealand's historical absence of egg-eating ground predators, while the mobile chicks would be able to evade chick-eating flying predators.Lice in the genus "Apterygon" and in the subgenus "Rallicola" ("Aptericola") are exclusively ectoparasites of kiwi species.## Status and conservation.Nationwide studies show that only around 5–10% of kiwi chicks survive to adulthood without management. As at 2018 over 70% of Kiwi populations are unmanaged. However, in areas under active pest management, survival rates for North Island brown.

Kiwi eggs and chicks are removed from the wild and hatched and/or raised in captivity until big enough.

An Operation Nest Egg bird has a 65% chance of surviving to adulthood—compared to just 5% for wild-hatched and raised chicks. The tool is used on all kiwi species except little spotted kiwi.## 1080 poison.In 2004, anti-1080 activist Phillip Anderton posed for the New Zealand media with a kiwi he claimed had been poisoned. An investigation revealed that Anderton lied to journalists and the public. He had used a kiwi that had been caught in a possum trap. Extensive monitoring shows.

Kiwi (bird). that kiwi are not at risk from the use of biodegradable 1080 poison.## Threats.Introduced mammalian predators, namely stoats, dogs, ferrets, and cats, are the principal threats to kiwi. The biggest threat to kiwi chicks is stoats, while dogs are the biggest threat to adult kiwi. Stoats are responsible for approximately half of kiwi chick deaths in many areas through New Zealand. Young kiwi chicks are vulnerable to stoat predation until they reach about 1 - 1.2 (kg) in weight, at which time they can usually defend themselves. Cats also to a lesser extent prey on kiwi chicks. These predators can.

Thermometer. in medicine, and in scientific research.## History.While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this closely, based on fixed points and interpolating thermometers. The most recent official temperature scale is the International Temperature Scale of 1990. It extends from 0.65 (K) to approximately 1358 (K).## Early developments.Various authors have credited the invention of the thermometer to Hero of Alexandria. The thermometer was not a single invention,.

The expansion and contraction of the air caused the position of the water/air interface to move along the tube.Such a mechanism was later used to show the hotness and coldness of the air with a tube in which the water level is controlled by the expansion and contraction of the gas. These devices were developed by several European scientists.

It is mainly migratory, wintering in Central America and breeding in northern Mexico and the southern United States. The male is blue with two brown . The female is mainly brown with scattered blue feathers on the upperparts and two brown wing bars.## Taxonomy.The blue grosbeak was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his "Systema Naturae" under the binomial name "Loxia caerulea". The specific epithet "caerulea" is the Latin word for "blue", "azure-blue", "sky-blue.

Blue grosbeak. or "dark-blue". Linnaeus based his own description on the "blew gross-beak" described and illustrated by Mark Catesby in his "The Natural History of Carolina, Florida and the Bahama Islands". The book had been published in 1729–1732. Catesby gave the location as Carolina and Linnaeus specified America. The type location is now restricted to South Carolina.Some taxonomists placed the blue grosbeak in its own monotypic genus "Guiraca" but in 2001 a molecular phylogenetic study of mitochondrial DNA sequences found that the blue grosbeak, in spite of being physically larger, nested within the "Passerina" and was most closely related to the lazuli.

The limpet's contours grow to fit the homesite rock surface tightly.## Life cycle.Owl limpets are protandric hermaphrodites. They spend about two years as juveniles before starting their reproductive lives as male limpets. If they survive long enough, some of them later transform into females. Spawning takes place once a year in the winter. The larvae are pelagic and form part of the zooplankton.

Lottia gigantea. They may be transported large distances by currents before settling on suitable rock surfaces.Larger individuals will themselves have encrusting animals such as barnacles and algae growing on their shells. Sometimes the shell will be used by other limpets or chitons for grazing on the microalgae that grows there. The black oystercatcher, "Haematopus bachmani" is the only known predator of the owl limpet but they are also harvested by humans for food.## Feeding habits.Large female limpets graze on the film of algae growing on rocks and defend their territory against other owl limpets, mobile gastropods, mussels, sea anemones, barnacles and macroalgae.

Lottia gigantea. Large competitors are dislodged by pushing them away with the anterior part of the shell, and if barnacles settle, they are rasped away with the radula. In this way, each individual maintains a territory of about 900 square centimetres. It selectively grazes its algal meadow maintaining a turf depth of at least one millimetre. In spring and summer, these green meadows are visible from fifteen metres away and if the owl limpet is transplanted to a new area, it establishes a new meadow over the course of about three weeks.

Eastern towhee. The eastern towhee ("Pipilo erythrophthalmus") is a large New World sparrow. The taxonomy of the towhees has been under debate in recent decades, and formerly this bird and the spotted towhee were considered a single species, the rufous-sided towhee.Their breeding habitat is brushy areas across eastern North America. They nest either low in bushes or on the ground under shrubs. Northern birds migrate to the southern United States. There has been one record of this species as a vagrant to western Europe: a single bird in Great Britain in 1966.The song is a short "drink your teeeeea" lasting around one.

Eastern towhee. second, starting with a sharp call ("drink!") and ending with a short trill "teeeeea". The name "towhee" is onomatopoeic description of one of the towhee's most common calls, a short two-part call rising in pitch and sometimes also called a "chewink" call.## Taxonomy.The eastern towhee was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his "Systema Naturae" and given the binomial name "Fringilla erythrophthalma". This species is now placed in the genus "Pipilo" that was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816. The specific name "erythrophthalmus/erythrophthalma" combines the Ancient Greek.

Eastern towhee. Ontario and Quebec south to Florida, and west to eastern Texas are noted in a literature review. Populations north of southern New England through northern Indiana and Illinois to southern Iowa primarily are summer residents."Pipilo e. erythrophthalmus" occurs in the most northerly part of the eastern towhee's distribution in the summer, and in winter migrates to the southern and eastern portion of the range of the species. The other subspecies are largely residents. "Pipilo e. canaster" occurs from south-central Louisiana, north to northeastern Louisiana east through Mississippi, extreme southwestern Tennessee, northern Alabama and Georgia, central South Carolina to western North.

Eastern towhee. Carolina, and south to northwestern Florida and east along the Gulf Coast. The range of "P. e. rileyi" extends from northern Florida through southern Georgia and coastal South Carolina to east-central North Carolina. "Pipilo e. alleni" occurs in peninsular Florida.The eastern towhee occurs in vegetation of disturbed areas, such as old-field successional vegetation and shrubby areas of power line right-of-ways. In northwestern Arkansas, eastern towhees occurred in old-field vegetation where dwarf sumac ("Rhus copallina") occurred at a frequency of 28.6%, winged elm ("Ulmus alata") at a frequency of 21%, and black cherry ("Prunus serotina") at a frequency of 19.2%.

A review of eastern towhees in New Hampshire describes arrival in late April to May with the majority departing in September. Further south, on the border of Tennessee and North Carolina, migration to high-elevation areas within the Great Smoky Mountains begins as early as March. Eastern towhees typically leave these sites in October. The "Pipilo e. erythrophthalmus" subspecies is the most migratory of the subspecies.Breeding begins in spring and continues to late summer.

Infrequent winter service provided by underpowered steamships incapable of breaking sea ice ensured the survival of a passenger and mail service across Abegweit Passage using iceboats until a permanent ferry service was established in the 1910s.The unsatisfactory winter steamship service and reliance upon primitive iceboats provoked complaints from the Island government until the federal government decided to implement a railcar ferry service across Abegweit Passage between new ports at Port Borden and Cape Tormentine.In 1912, the federal government promised to open a car ferry between the "Capes" (Cape Traverse, PEI to Cape.

The privately owned New Brunswick and Prince Edward Island Railway from Sackville, New Brunswick to Cape Tormentine was purchased by the federal government and an order was made with a shipyard in England for an icebreaking railcar ferry, to be called the "Prince Edward Island". Ports were developed at Carleton Point, several kilometres west of Cape Traverse, and the existing harbour at Cape Tormentine; the new port at Carleton Point would be named Borden in honour of Prime Minister Sir Robert Borden.The new ferry entered service in 1915 and operated on the former steamship routes until port facilities.
