SYNCHRONOUS MOTOR DRIVES. In a synchronous motor, a 3-phase set of stator currents produces a rotating magnetic field causing the rotor magnetic field to align with it. The rotor magnetic field is produced by a DC current applied to the rotor winding. Field windings are the windings producing the main magnetic field (rotor windings for synchronous machines);
