WebNo mechanical power is needed for the functioning of an AC Motor. Based on the operational principle, AC Motors are classifed as: Synchronous and Asynchronous Motors. Based on the current type, AC Motors are classified as single and three-phase motors. Based on the operational speed, AC Motors are classified as Variable and Constant Speed. WebWorking principle of a synchronous motor. The principle of operation of a synchronous motor is based on the interaction of the rotating magnetic field of the stator and the constant magnetic field of the rotor. The concept of the rotating magnetic field of the stator of a synchronous motor is the same as that of a three-phase induction motor.

WebWorking principle of DC motor. When kept in a magnetic field, a current-carrying conductor gains torque and develops a tendency to move. In short, when electric fields and magnetic fields interact, a mechanical force arises. This is the principle on which the DC motors work.
