The term, stator is derived from the word stationary. The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. It also consists of a group of electro-magnets arranged around a cylinder, with the poles facing toward the stator poles.The rotor is located inside the stator and is mounted on the AC motor's shaft.hus, as the magnetic field of the stator rotates, the rotor is forced to rotate with it. One way to produce a rotating magnetic field in the stator of an AC Motor is to use a three-phase power supply for the stator coils.
