Synchronous Motors If the field circuit of an unloaded salientpole synchronous motor gets suddenly open-circuited, then it runs at a slower speed it runs at a very high speed the motor stops it continues to run at the same speed it runs at a slower speed it runs at a very high speed the motor stops it continues to run at the same speed ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors In case one phase of a three-phase synchronous motor is short-circuited the motor will take less than the rated load run with excessive vibrations not start run at 2/3 of synchronous speed take less than the rated load run with excessive vibrations not start run at 2/3 of synchronous speed ANSWER DOWNLOAD EXAMIANS APP
