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.
