Synchronous Motors If the field circuit of an unloaded salientpole synchronous motor gets suddenly open-circuited, then the motor stops it runs at a slower speed it continues to run at the same speed it runs at a very high speed the motor stops it runs at a slower speed it continues to run at the same speed it runs at a very high speed ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors If the synchronous motor, properly synchronised to the supply is running on no load and is having negligible loss then the stator current will be very high the stator current will be zero the back e.m.f. will be more than the supply voltage the stator current will be very small the stator current will be very high the stator current will be zero the back e.m.f. will be more than the supply voltage the stator current will be very small ANSWER DOWNLOAD EXAMIANS APP
