How Electric Motors are made Three phase AC induction motor
... The induction motor is probably the most common of all motors. Like the de machine, an induction motor consists of a stator and a rotor, the latter mounted on bearings and separated from the stator by an airgap. The stator core, made up of punchings (or laminations), carries slot-embedded conductor ...

Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same line to ground voltage because it uses less conductor material to transmit electrical power.The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström and Nikola Tesla in the late 1880s.
