What Is Damper Winding?

: a short-circuited squirrel-cage winding placed in the pole faces and around the pole shoes of synchronous machines, the currents induced in the winding by the periodic variations in synchronous speed having the effect of a damper. — called also amortisseur.

What is use of damper winding?

Damper windings helps the synchronous motor to start on its own (self starting machine) by providing starting torque. By providing damper windings in the rotor of synchronous motor “Hunting of machine”can be suppressed.

Where are damper windings?

Damper winding in an alternator is also known as squirrel-cage winding. This winding is located inside the slotted pole shoes of the alternator. Prevents hunting (momentarily speed fluctuations) in the alternator, Increases the transient stability.
