Answer Posted / mehmed
damper windings are mainly used to provide startn torque
for sync motors.though under the normal running
condition,the damper still carry little current even the
rotor runs at a synchronous speed, it still can be removed.
i already done the lab experiment.
its another purpose is to prevent hunting(i.e,momentary speed
fluctuation) n helps the motor to run @ sync speed by
preventing oscillations.
