1. Stator:
The stator consists of three-phase windings, similar to an induction motor.
When AC power is supplied to these windings, it creates a rotating magnetic field. This field rotates at a speed determined by the frequency of the AC supply and the number of poles in the stator winding (synchronous speed).
