Polyphase motors can be both two-period or 3-section motors. They function like solitary-period induction motors, but both single-stage and polyphase motors work on a rotating magnetic field. Their rotating magnetic fields are generated by two- or 3-stage currents passing via two or far more sets of coils. The rotating magnetic area makes torque. Polyphase motors are employed in purposes that call for substantial electrical power, these kinds of as the power generate of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
