PERMANENT MAGNET SYNCHRONOUS MOTOR
, 2022 Synchronous machine (CM) is an alternating current electric machine whose rotor speed is directed in the same direction as the speed of the electromagnetic field. In a synchronous generator with permanent magnets on the rotor, there is no excitation winding, and the magnetic flux of excitation is created due to permanent magnets, not coils.
