Centaurea cineraria. Centaurea cineraria, the velvet centaurea, is – like some other plants – also known as dusty miller and silver dust. It is a small plant in the family Asteraceae and originates from the Island of Capraia in Italy, where it is called fiordaliso delle scogliere.The mature plants will grow from 15 to 60 (cm). They prefer full sun, but will tolerate light shade, and also prefers average to rich well-drained soil."Centaurea cineraria" will produce small white or yellow flowers in summer, but these are usually trimmed because the plant is normally grown as foliage.Depending on climate, it can be grown.

Centaurea cineraria. as either an annual or as a perennial."Centaurea cineraria" is polymorphic in several characters, and the high variation within populations gives rise to many subspecies which causes "C. cineraria" to be referred to under a wide variety of different synonyms.Common cultivars include:'Silver Dust', 'Silver Lace' and 'Cirrus'. The image above the scientific classification is a plant of the 'Silver Lace' cultivar."Centaurea cineraria" is sometimes referred to as "Centaurea gymnocarpa," as a hybrid species between the two is used in gardens as an ornamental plant.

Kalmia. Kalmia is a genus of about ten species of evergreen shrubs from 0.2–5 m tall, in the family Ericaceae. They are native to North America (mainly in the eastern half of the continent) and Cuba. They grow in acidic soils, with different species in wet acid bog habitats ("K. angustifolia, K. polifolia") and dry, sandy soils ("K. ericoides, K. latifolia")."Kalmia" was named by Linnaeus to honour his friend the botanist Pehr Kalm, who collected it in eastern North America during the mid-18th century. Earlier, Mark Catesby saw it during his travels in Carolina, and after his return to England in.

Kalmia. 1726, imported seeds. He described it, a costly rarity, in his "Natural History of Carolina", as "Chamaedaphne foliis tini", that is to say "with leaves like the Laurustinus"; the botanist and plant-collector Peter Collinson, who had begged some of the shrub from his correspondent John Custis in Virginia, wrote, when his plants flowered, that "I Really Think it exceeds the Laurus Tinus."The leaves are 2–12 cm long and simple lanceolate. The flowers are white, pink or purple, in corymbs of 10-50, reminiscent of Rhododendron flowers but flatter, with a star-like calyx of five conjoined petals; each flower is 1–3 cm.

The fruit is a five-lobed capsule, which splits to release the numerous small seeds.The foliage contains grayanotoxins, a group of closely related neurotoxins named after "Leucothoe grayana", native to Japan, so it is toxic if eaten, with sheep being particularly prone to poisoning, hence the name lambkill used for some of the species. Other names for Kalmia, particularly "Kalmia angustifolia," are sheep-laurel, lamb-kill, calf-kill, kill-kid, and sheep-poison, which may be written with or without the hyphen. (See species list below.) "Kid" here refers to a young goat, not a human child, but the foliage and twigs are toxic to.

Kalmia. humans as well.It has also been called spoonwood because Kalm was told by Dutch settlers of North America that Native Americans made spoons from the wood. Given its toxicity, this may be folklore rather than scientific fact.Kalmias are popular garden shrubs, grown for their decorative flowers. They should not be planted where they are accessible to livestock due to the toxicity."Kalmia" species are used as food plants by the larvae of some lepidopteran species including "Coleophora kalmiella" which feeds exclusively on "Kalmia".## Species.Species (and infraspecific taxa) listed by The Plant List as "Accepted": "Kalmia angustifolia" - Sheep-laurel, lambkill "Kalmia buxifolia.

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.

Brassica juncea, commonly brown mustard, Chinese mustard, Indian mustard, leaf mustard, Oriental mustard and vegetable mustard, is a species of mustard plant.## Cultivar."Brassica juncea" cultivars can be divided into four major subgroups: integrifolia, juncea, napiformis, and tsatsai.## Uses.## Nutrition.In a 100 (g) reference serving, cooked mustard greens provide 26 (kcal) of food energy and are a rich source (20% or more of the Daily Value) of vitamins A, C, and K—K being especially high as a multiple of its Daily Value. Mustard greens are a moderate source of vitamin E and calcium. Greens are 92% water, 4.5% carbohydrates, 2.6% protein.

Brassica juncea. and 0.5% fat (table).## Cuisine.The leaves, seeds, and stems of this mustard variety are edible. The plant appears in some form in African, Bangladeshi, Chinese, Filipino, Italian, Indian, Japanese, Nepali, Pakistani, Korean, Southern and African-American (soul food) cuisines. Cultivars of "B. juncea" are grown for their greens, and for the production of mustard oil. The mustard condiment made from the seeds of the "B. juncea" is called brown mustard and is considered to be spicier than yellow mustard.Because it may contain erucic acid, a potential toxin, mustard oil is restricted from import as a vegetable oil into the United States.

Brassica juncea. Essential oil of mustard, however, is generally recognized as safe by the U.S. Food and Drug Administration. In Russia, this is the main species grown for the production of mustard oil. It is widely used in canning, baking and margarine production in Russia, and the majority of Russian table mustard is also made from "B. juncea".The leaves are used in African cooking, and all plant parts are used in Nepali cuisine, particularly in the mountain regions of Nepal, as well as in the Punjabi cuisine in the northern part of the Indian subcontinent, where a dish called "sarson da saag.

Brassica juncea. (mustard greens) is prepared. "B. juncea" subsp. "tatsai", which has a particularly thick stem, is used to make the Nepali pickle called "achar", and the Chinese pickle "zha cai".This plant is called "lai xaak" in Assamese and it is cultivated hugely during the winters. It is eaten in any form in Assam and Northeast, be it boiled or added raw in salad, cooked alone or with pork.The Gorkhas of the Indian states of Darjeeling, West Bengal and Sikkim as well as Nepal prepare pork with mustard greens (also called "rayo" in Nepali). It is usually eaten with relish and steamed.

In Nepal it is also a common practice to cook these greens with meat of all sorts, especially goat meat; which is normally prepared in a pressure cooker with minimal use of spices to focus on the flavour of the greens and dry chillies. "B. juncea" (especially the seeds) is more pungent than greens from the closely related "B. oleracea" (kale, broccoli, and collard greens), and is frequently mixed with these milder greens in a dish of "mixed greens".Chinese and Japanese cuisines also make use of mustard greens. In Japanese.

Many varieties of "B. juncea" cultivars are used, including "zha cai", "mizuna", "takana" (var. "integrifolia"), "juk gai choy", and "xuelihong". Asian mustard greens are most often stir-fried or pickled. A Southeast Asian dish called "asam gai choy" or "kiam chai boey" is often made with leftovers from a large meal. It involves stewing mustard greens with tamarind, dried chillies and leftover meat on the bone. Brassica juncea is also known as "gai choi", "siu gai choi", "xaio jie cai", baby mustard,.

Brassica juncea. Chinese leaf mustard or "mostaza".## Green manure.Vegetable growers sometimes grow mustard as a green manure. Its main purpose is to act as a mulch, covering the soil to suppress weeds between crops. If grown as a green manure, the mustard plants are cut down at the base when sufficiently grown, and left to wither on the surface, continuing to act as a mulch until the next crop is due for sowing, when the mustard is dug in. In the UK, mustard sown in summer and autumn is cut down starting in October. April sowings can be cut down in June,.

One of the disadvantages of using mustard as a green manure is its propensity to harbor club root.## Phytoremediation.This mustard plant is used in phytoremediation to remove heavy metals, such as lead, from the soil in hazardous waste sites because it has a higher tolerance for these substances and stores the heavy metals in its cells. In particular, "Brassica juncea" was particularly effective at removing cadmium from soil. The process of removing heavy metals ends when the plant is harvested and properly discarded.

Franz Joseph Bridge. Franz Joseph Bridge (), later renamed Štefanik Bridge (), was a suspension bridge over the Vltava in Prague, opened in 1868.The bridge was designed by the English engineer Rowland Mason Ordish. The design, which used the Ordish–Lefeuvre system, was originally created for the Albert Bridge over the River Thames in London.

Woodsia. Woodsia is a genus of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only genus in the family Woodsiaceae, placed in the suborder Aspleniineae. The family can also be treated as the subfamily Woodsioideae of a very broadly defined family Aspleniaceae "sensu lato". Species of "Woodsia" are commonly known as cliff ferns.## Taxonomy.Woodsiaceae formerly included the members of the families Athyriaceae and Diplaziopsidaceae, but analysis has consistently shown that they should be treated as separate families.

Spotted hyena. The spotted hyena (Crocuta crocuta), also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus "Crocuta", native to sub-Saharan Africa. It is listed as being of least concern by the IUCN on account of its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. The species may have originated in Asia, and once ranged throughout Europe for at least one million years until the end of the Late Pleistocene. The spotted hyena.

Spotted hyena. Western perceptions on the species can be found in the writings of Aristotle and Pliny the Elder, though in relatively unjudgmental form. Explicit, negative judgments occur in the "Physiologus", where the animal is depicted as a hermaphrodite and grave-robber. The IUCN's hyena specialist group identifies the spotted hyena's negative reputation as detrimental to the species' continued survival, both in captivity and the wild.## Etymology and naming.The spotted hyena's scientific name "Crocuta", was once widely thought to be derived from the Latin loanword , which translates as 'saffron-coloured one', in reference to the animal's fur colour. This was proven to be.

Spotted hyena. incorrect, as the correct spelling of the loanword would have been "Crocāta", and the word was never used in that sense by Graeco-Roman sources. "Crocuta" actually comes from the Ancient Greek word (), which is derived from the Sanskrit , which in turn originates from (both of which were originally meant to signify the golden jackal). The earliest recorded mention of Κροκόττας is from Strabo's "Geographica", where the animal is described as a mix of wolf and dog native to Ethiopia.From Classical antiquity until the Renaissance, the spotted and striped hyena were either assumed to be the same species, or.

Spotted hyena. distinguished purely on geographical, rather than physical grounds. Hiob Ludolf, in his , was the first to clearly distinguish the "Crocuta" from "Hyaena" on account of physical, as well as geographical grounds, though he never had any first hand experience of the species, having gotten his accounts from an Ethiopian intermediary. Confusion still persisted over the exact taxonomic nature of the hyena family in general, with most European travelers in Ethiopia referring to hyenas as "wolves". This partly stems from the Amharic word for hyena, (), which is linked to the Arabic word () 'wolf'.The first detailed first-hand descriptions of.

Spotted hyena. as "wolves".Bosman and Kolben's descriptions went largely unnoticed until 1771, when the Welsh naturalist Thomas Pennant, in his "Synopsis of Quadrupeds", used the descriptions, as well as his personal experience with a captive specimen, as a basis for consistently differentiating the spotted hyena from the striped. The description given by Pennant was precise enough to be included by Johann Erxleben in his by simply translating Pennant's text into Latin. "Crocuta" was finally recognised as a separate genus from "Hyaena" in 1828.## Taxonomy, origins and evolution.Unlike the striped hyena, for which a number of subspecies were proposed in light of its.

Spotted hyena. single population, with the only set of characters standing out being pelage (which is subject to a high degree of individual variation) and size (which is subject to Bergmann's Rule). When fossils are taken into consideration, the species displayed even greater variation than it does in modern times, and a number of these named fossil species have since been classed as synonymous with "Crocuta crocuta", with firm evidence of there being more than one species within the genus "Crocuta" still lacking.Both Björn Kurtén and Camille Arambourg promoted an Asiatic origin for the species; Kurtén focussed his arguments on the Plio-Pleistocene.

Spotted hyena. taxon "Crocuta sivalensis" from the Siwaliks, a view defended by Arambourg, who nonetheless allowed the possibility of an Indo-Ethiopian origin. This stance was contested by Ficarelli and Torre, who referred to evidence of the spotted hyena's presence from African deposits dating from the early Pleistocene, a similar age to the Asian "C. sivalensis". Studies on the phylogeographic distribution of mtDNA haplotypes indicates three migration events from Africa to Eurasia, though neither the topology of the phylogenetic tree or the fossil record exclude the possibility of an Asian origin. The earliest migration of spotted hyenas from Africa to Eurasia began less.

Spotted hyena. to suggest that spotted hyenas underwent a genetic bottleneck during the Pleistocene.The ancestors of the genus "Crocuta" diverged from "Hyaena" (the genus of striped and brown hyenas) 10 million years ago. The ancestors of the spotted hyena probably developed social behaviours in response to increased pressure from other predators on carcasses, which forced them to operate in teams. At one point in their evolution, spotted hyenas developed sharp carnassials behind their crushing premolars; this rendered waiting for their prey to die no longer a necessity, as is the case for brown and striped hyenas, and thus they became pack hunters.


Question: What is the hymenium type of this plant?

Instruction: You have to find a Wikipedia segment that answers the question about the displayed image.

Astraeus hygrometricus. common in temperate and tropical regions. Its common names refer to the fact that it is hygroscopic (water-absorbing), and can open up its rays to expose the spore sac in response to increased humidity, and close them up again in drier conditions. The rays have an irregularly cracked surface, while the spore case is pale brown and smooth with an irregular slit or tear at the top. The gleba is white initially, but turns brown and powdery when the spores mature. The spores are reddish-brown, roughly spherical with minute warts, measuring 7.5–11 micrometers in diameter.Despite a similar overall appearance, "A.

Astraeus hygrometricus. alternate spelling of "Geastrum"). According to the American botanist Andrew P. Morgan, however, the species differed from those of "Geastrum" in not having open chambers in the young gleba, having larger and branched capillitium threads, not having a true hymenium, and having larger spores. Accordingly, Morgan set Persoon's "Geaster hygrometricum" as the type species of his new genus "Astraeus" in 1889. Despite Morgan's publication, some authorities in the following decades continued to classify the species in "Geastrum". The New-Zealand based mycologist Gordon Herriot Cunningham explicitly transferred the species back to the genus "Geastrum" in 1944, explaining: The treatment of this.

Astraeus hygrometricus. species by certain taxonomists well illustrates the pitfalls that lie in wait for those who worship at the shrine of ontogenic classification ... The only feature of those outlined in which the species differs from others of "Geastrum" is the somewhat primitive hymenium. In the developing plant the glebal cavities are separated by tramal plates so tenuous as to be overlooked by the uncritical worker. Each cavity is filled with basidia somewhat irregularly arranged in clusters (like those of "Scleroderma") and not in the definite palisade of the species which have been studied. This difference disappears as maturity is reached,.

Astraeus hygrometricus. interior of the spore case, the gleba, is white and solid when young, and divided into oval locules—a characteristic that helps to distinguish it from "Geastrum". The gleba becomes brown and powdery as the specimen matures. Small dark hairlike threads (rhizomorphs) extend from the base of the fruit body into the substrate. The rhizomorphs are fragile, and often break off after maturity.The spores are spherical or nearly so, reddish-brown, thick-walled and verrucose (covered with warts and spines). The spores' dimensions are 7–11 µm; the warts are about 1 µm long. The spores are non-amyloid, and will not stain with iodine.

Astraeus hygrometricus. published before it was known that North American and Asian versions of "A. hygrometricus" were not always the same; in some cases Asian specimens have been identified as new species, such as "A. asiaticus" and "A. odoratus".## Similar species.Although "A. hygrometricus" bears a superficial resemblance to members of the "true earthstars" "Geastrum", it may be readily differentiated from most by the hygroscopic nature of its rays. Hygroscopic earthstars include "G. arenarium", "G. corollinum", "G. floriforme", "G. recolligens", and "G. kotlabae". Unlike "Geastrum", the young fruit bodies of "A. hygrometricus" do not have a columella (sterile tissue in the gleba, at.

Astraeus hygrometricus. moist soil. The spore ornamentation of "A. odoratus" is also distinct from "A. hygrometricus", with longer and narrower spines that often joined. "A. asiaticus" has an outer peridial surface covered with small granules, and a gleba that is purplish-chestnut in color, compared to the smooth peridial surface and brownish gleba of "A. hygrometricus". The upper limit of the spore size of "A. asiaticus" is larger than that of its more common relative, ranging from 8.75 to 15.2 μm. "A. koreanus" (sometimes named as the variety "A. hygrometricus" var. "koreanus"; see Taxonomy) differs from the more common form in its smaller.

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.

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.

Looshaus. The Looshaus is a commercial and residential building at 3, between Herrengasse and , in Vienna. Designed by Adolf Loos and completed in 1912, it is considered a major building of Viennese Modernism.## Building.The modernist design of the Looshaus contrasts with both historicism and the floral ornament of Secessionist architecture. Although functionalist, it is far from purely utilitarian. In particular, it makes use of sumptuous materials. The lower, commercial section of the façade is clad in green Cipollino marble from Euboea, in striking contrast with the simple plaster of the upper, residential section. A colonnade of Tuscan columns was intended.

Looshaus. to allude to the portico of the St. Michael's Church on the same square. The upper storeys are unornamented except for window boxes; according to legend, these were intended to allude to the Hofburg by resembling the Archducal hat in form; the Looshaus is opposite its north façade ("Michaelertrakt").The Looshaus was a pioneering reinforced concrete building in Vienna; this form of construction made possible large interior spaces and rational grouping of the manufacturing and sales areas, and Loos also used varied ceiling heights to save space. The street-level salesroom was divided by four interior columns into distinct areas, and had.

Looshaus. oval display windows and furnishings sourced by Loos in England. Three mezzanine levels served by short flights of stairs housed reception and changing rooms above the main sales floor, as well as offices and the accounting department in the centre, and extending on two levels over rented commercial space on the two side streets, store rooms and work rooms for all the stages in the production of clothing. Customer areas were unified by mahogany-clad pillars, consistent marble flooring, and brass; the screened-off production areas were finished in exposed concrete. Two sets of stairs and two elevator shafts served the upper.

Looshaus. floors, including apprentice instruction and a private vocational school which shared the top floor.## History.Emanuel Aufricht and Leopold Goldman, the owners of , a men's clothing company with an upper-class clientele, held a design competition for a building to house their sales, manufacturing, and office functions as well as Goldman's private apartment. The competition failed to produce a design that satisfied them, so in 1909 they gave the commission to Adolf Loos, who had been invited to submit a design but had not done so. The building was constructed by , with Ernst Epstein as construction manager. However, although the.

Looshaus. city had accepted the plans, in 1910 the unornamented upper storeys caused a scandal; construction was permitted to proceed only after Loos added window boxes with flowers to mitigate what one of many insulting articles in the press called their "inappropriate nakedness", and defended his design in a public meeting. It was finally completed in 1912. Reportedly, Emperor Franz Joseph disliked the Looshaus so much that he ordered the curtains on the windows of the Hofburg facing the square to remain closed. Under the Nazis, the commercial levels of the Looshaus were converted into an Opel showroom. In 1944 the.

Looshaus. building was affected by a bomb strike on an adjacent building. In 1947 it became a protected monument; it was somewhat unsuccessfully restored in the 1950s and in the 1960s housed a furniture shop. In 1987 the Raiffeisenbank bought it and thoroughly renovated it, restoring the commercial levels to their original appearance.In the early 2000s, "Designzone Looshaus", a facility designed by Paolo Piva for exhibitions and conferences showcasing Austrian design, opened in the basement of the Looshaus. The winners of the biennial are exhibited there. Adolf Loos-Haus, Raffeisenbank, archived on 28 February 2022.

Hickory. Rocky Mountains.Fossils of early hickory nuts show simpler, thinner shells than modern species with the exception of pecans, suggesting that the trees gradually developed defenses to rodent seed predation. During this time, the genus had a distribution across the Northern Hemisphere, but the Pleistocene Ice Age beginning 2 million years ago obliterated it from Europe. The distribution of Carya in North America also contracted and it completely disappeared from the continent west of the Rocky Mountains. Since fossil records show North America as having the largest number of Juglandaceae species, it is likely that the genus originated there and later.

Hickory nuts ("Carya") and walnuts ("Juglans") in the Juglandaceae family grow within an outer husk; these fruits are sometimes considered to be drupes or drupaceous nuts, rather than true botanical nuts. "Tryma" is a specialized term for such nut-like drupes.## Nutrition.Dried hickory nuts are 3% water, 18% carbohydrates, 13% protein, and 64% fats (table). In a 100 gram (3.5 oz) reference amount, dried hickory nuts supply 657 calories, and are a rich source (20% or more of the Daily Value, DV) of several B vitamins and dietary.
