Why Synchronous Motor is not Self starting?
What is Damper winding?
Damper winding kyu use karte hai
A synchronous motor is one in which the rotor normally rotates at the same speed as the revolving field in the machine. The stator is similar to that of an induction machine consisting of a cylindrical iron frame with windings, usually three-phase, located in slots around the inner periphery.
due to the inertia of the rotor, it is unable to rotate in any direction due to attractive or repulsive force and remain in standstill condition.
The synchronous motor is made self-starting by providing a special winding on the rotor poles, known as damper winding or squirrel cage winding.
