what are the functions of damping windings in a machine
Function of damper winding in synchronous machine: 1.Self starting of synchronous machine: The core concept is that damper winding being short circuited carry high current, creates magnetic flux like as induction machine.Thus there is pulling in or better torque in starting.he rotor of induction machine is mostly of squirrel cage type which is short circuited thus provides high current in start up. Damper winding in synchronous machine is placed in the coil slots and short circuited.
