Answer Posted / rakesh kumar
in case of a synchronous motor once the excitation is cut
off , then the motor starts to run as an induction motor,
this is because a synchronous motor by itself is not self
starting , and is first started as a squirrel cage
induction motor , once the motor attains about 95% of
synchronous speed then the excitation is applied due to
which the the copper bars are effectively removed from the
circuit as they revolve with the sane speed as the rotating
flux , once the excitation is cut off , the relative motion
between flux and the copper bars come into action and the
motor starts operating as a induction motor.
