Damper winding are winding that are would to the Rotor poles of the Machine (winding it similar to that of an inductor Machine) which will in two way. ● We all know that a Synchronous Machine is not self starting. Thus providing damper windings help Synchronous Machine to act as an induction Motor (only at starting) which helps the Machine to self start. ● We all know that hunting is a Persistent Phenomenon when it come to Synchronous Machine, we can Reduce hunting to a great extent by damping it. They don't let the Motor to oscillate obruptly, they damp the oscillations thus increasing the stability of the Machine.
