Hey, I understand that damper windings are used to stabilize the speed of the rotor under varying loads. The rotor speed is decreased or increased by the induction principle. Physically the damped windings are some sort of copper bars inserted into the pole faces of a rotor and all connected together by a copper ring. Here comes my problem: I am working on a project, where I have a generator that needs to have a certain damping coefficient (units in my case are kg/s). Is there a formula to determine the damping coefficient of my generator?
