If the damper winding on the rotor of a synchronous motor is
removed after starting what will happen?

Answer Posted / meenakshi

damper windings are mainly used to provide startn torque
for sync motors.though under the normal running
condition,the damper does not carry any current since the
rotor runs at a synchronous speed, it cannot b removed.its
another purpose is to prevent hunting(i.e,momentary speed
fluctuation) n helps the motor to run @ sync speed by
preventing oscillations.
