Polyphase motors can be either two-period or 3-section motors. They work like one-stage induction motors, but both solitary-period and polyphase motors run on a rotating magnetic discipline. Their rotating magnetic fields are produced by two- or a few-period currents passing through two or far more sets of coils. The rotating magnetic discipline makes torque. Polyphase motors are employed in purposes that demand high electrical power, these kinds of as the electricity generate of compressors, hydraulic pumps, air conditioning compressors, and irrigation pumps.
The rotor of a reluctance motor is made up of a sound cast steel portion with a convex toothed rack. Their starting process is related to an induction motor, but it operates like a synchronous motor. Typically, their rotors have less poles than stators, which minimizes torque ripple and prevents excellent pole alignment, as no torque is developed in that place. Reluctance motors assortment in energy scores from a handful of watts to about 22 kilowatts.
