Jan 17, 2025 · Electric motor, any of a class of devices that convert electrical energy to mechanical energy, usually by employing electromagnetic phenomena. Most electric motors develop their mechanical torque by the interaction of conductors carrying current in a direction at right angles to a magnetic field.

Jan 17, 2025 · Electric motor - Permanent Magnet, Rotor, Stator: The magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium-boron-iron, samarium-cobalt, or ferrite on the rotor.

Jan 17, 2025 · Electric motor - Linear Induction, Magnetic Fields, Propulsion: A linear induction motor provides linear force and motion rather than rotational torque. The shape and operation of a linear induction motor can be visualized as depicted in the figure by making a radial cut in a rotating induction machine and flattening it out.

Jan 17, 2025 · Electric motor - Synchronous, Rotating Fields, AC Motors: A synchronous motor is one in which the rotor normally rotates at the same speed as the revolving field in the machine. The stator is similar to that of an induction machine consisting of a cylindrical iron frame with windings, usually three-phase, located in slots around the inner ...

Jan 17, 2025 · Electric motor - Induction, Rotor, Stator: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors.

Jan 17, 2025 · Electric motor - Single Phase, Induction, Rotating Field: The development of a rotating field in an induction machine requires a set of currents displaced in phase (as shown in the figure) flowing in a set of stator windings that are displaced around the stator periphery.

Jan 27, 2025 · Tesla, Inc. is an American manufacturer of electric automobiles, solar panels, and batteries for cars and home power storage. It was founded in 2003 by American entrepreneurs Martin Eberhard and Marc Tarpenning and was named …

Jan 17, 2025 · Electric motor - Capacitor, Induction, Rotor: This motor is similar to the three-phase motor except that it has only two windings (a-a′ and b-b′) on its stator displaced 90° from each other. The a-a′ winding is connected directly to the single-phase supply.

Thomas Davenport (born July 9, 1802, Williamstown, Vt., U.S.—died July 6, 1851, Salisbury, Vt.) was an American inventor of what was probably the first commercially successful electric motor, which he used with great ingenuity to power a number of established inventions.

Nov 30, 2024 · Sturgeon built an electric motor in 1832 and invented the commutator, an integral part of most modern electric motors. In 1836, the year he founded the monthly journal Annals of Electricity, he invented the first suspended coil galvanometer, a device for measuring current. He also improved the voltaic battery and worked on the theory of ...
