Polyphase motors can be either two-stage or three-section motors. They perform like single-stage induction motors, but both single-period and polyphase motors work on a rotating magnetic area. Their rotating magnetic fields are created by two- or a few-section currents passing by way of two or far more sets of coils. The rotating magnetic subject creates torque. Polyphase motors are utilized in applications that require substantial power, this sort of as the electrical power travel of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
