Electric Motor for Alternating Current

<< >>
Description (Brief)
An electric motor was one of the critical components needed to make an electrical power system based on alternating current. Electrical inventor Nikola Tesla developed a revolutionary motor based on electromagnetic induction that featured rotating magnetic fields to drive the central armature. Engineers working for George Westinghouse refined Tesla’s concept and introduced this model A two-phase motor in 1888. The armature core is of the Siemens drum-type, a design intended to minimize the number of wire windings.
