What is damper bar and damper winding?

Dampers are used to provide additional damping in salient pole synchronous machine. Damping is provided by means of damper bars located in the main poles of the machine and short-circuited through round rings at both ends.

Where is damper winding in synchronous motor?

Synchronous motors have their pole-shoes slotted for placing copper bars. The copper bars are placed in these slots and short-circuited at both ends by heavy copper rings (like squirrel cage rotor of induction motors). This arrangement is known as damper winding in synchronous motor.
