Polyphase motors can be both two-period or a few-phase motors. They work like single-section induction motors, but the two solitary-phase and polyphase motors operate on a rotating magnetic discipline. Their rotating magnetic fields are created by two- or a few-phase currents passing by way of two or far more sets of coils. The rotating magnetic subject creates torque. Polyphase motors are utilised in programs that demand higher power, these kinds of as the electrical power push of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
