Jul 07 2021 The rotor rotating shaft is directly connected to the prime mover and rotates as the prime mover turns. The rotor contains a magnet that when turned produces a moving or rotating magnetic field. The rotor is surrounded by a stationary casing called the stator which contains the wound copper coils or windings.
