principle operation for synchronous motor

Synchronous motor construction is very similar to synchronous generator construction except that most motors are salientpole machines. Principle and Operation of Synchronous Motor When an induction motor is connected to a threephase supply, a rotating magnetic field is established; this induces currents in the rotor windings, thereby producing a torque.
