If the damper winding on the rotor of a synchronous motor is
removed after starting what will happen?
Answer Posted / deepak tyagi
When synchronous motor get started than it run at
synchronous speed. at this time damper has not current. the
second purpose is it provied synchronzing power in case of
disturbance.this power pull the machine in the synchronizm
again. so if we remove the after starting than machine will
work in synchronizm but as load incresed machine will not
work as synchronous motor.
