If the damper winding on the rotor of a synchronous motor is
removed after starting what will happen?
Answer Posted / sara ashfaq
1- Damper windings helps the synchronous motor to start
on its own (self starting machine) by providing starting torque
2- By providing damper windings in the rotor of
synchronous motor "Hunting of machine"can be suppressed.When
there is change in load, excitation or change in other
conditions of the systems rotor of the synchronous motor
will oscillate to and fro about an equilibrium position. At
times these oscillations becomes more violent and resulting
in loss of synchronism of the motor and comes to halt
