Polyphase motors can be possibly two-period or 3-section motors. They operate like single-period induction motors, but each solitary-period and polyphase motors function on a rotating magnetic subject. Their rotating magnetic fields are produced by two- or a few-phase currents passing through two or a lot more sets of coils. The rotating magnetic area generates torque. Polyphase motors are used in applications that call for higher electricity, such as the energy drive of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
