Polyphase motors can be possibly two-section or 3-stage motors. They work like solitary-stage induction motors, but equally solitary-stage and polyphase motors operate on a rotating magnetic subject. Their rotating magnetic fields are generated by two- or a few-period currents passing by way of two or far more sets of coils. The rotating magnetic area produces torque. Polyphase motors are employed in purposes that call for higher energy, these kinds of as the energy drive of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
