What is the purpose of damper bars in a synchronous machine?

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.

What is damper in vibration?

Vibration dampers are used to absorb vibration emanating from machinery, pedestrian traffic, etc. primarily to reduce the noise associated with such vibration and to procure a more comfortable environment.

How to Calculate Diameter of Damper Bar?

Diameter of Damper Bar calculator uses Diameter of Damper Bar = sqrt((4*Area of Damper Winding)/pi) to calculate the Diameter of Damper Bar, Diameter of damper bar is the distance from one point on the surface of a circle to the other point on the surface of the circle through the centre. The diameter of a damper bar, also known as a damper winding or amortisseur winding, in an electrical machine can be determined based on various factors such as machine design requirements, damping characteristics, and mechanical considerations. Diameter of Damper Bar is denoted by Dd symbol.
