Synchronous AC motors use a permanent magnet rotor, while induction motors use an electromagnet rotor. Explain what practical diﬀerence this makes in each motor’s operation, and also explain the meaning of the motors’ names.
The Theory of Induction Motors 1. When a voltage is applied to the stator of an induction motor, a magnetic field begins to rotate in the stator.
