motor is around 60% at its design rated speed and load. This efficiency may decrease further, depending on load and operating speed. A large factor in PSC motor efficiency is rotor loss. In PSC motors, the magnetic field (north and south poles) of the rotor is created by an inductive magnetic force from the stator.
