Synchronous Motors Quiz

A synchronous motor is a type of AC motor that runs at a constant speed. It generates a rotating magnetic field (RMF) that runs at a constant speed. Its working principle involves converting electrical energy into mechanical energy and it is a self-excited motor that does not require external starters to start the motor.

A synchronous motor is known as a constant speed motor because it runs at a constant speed, maintaining synchronous speed with the rotating magnetic field it generates.

The construction of a synchronous motor is similar to that of an alternator, as both are synchronous machines. The synchronous motor construction is basically similar to a rotating field type alternator.

<p>The main components of a synchronous motor are the stator and the rotor. The stator consists of a three-phase star winding, and the construction is similar to that of a rotating field type alternator.</p> Signup and view all the answers

<p>A key feature of a synchronous motor that distinguishes it from a single-phase induction motor is that it does not need any external starters to start the motor, unlike a single-phase induction motor.</p> Signup and view all the answers
