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 The duration of sudden short-circuit test on a synchronous motor is usually about one hour one second one minute None of these one hour one second one minute None of these ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors The power factor of a synchronous motor is better than that of induction motor because mechanical load on the motor can be adjusted synchronous motor runs at synchronous speed stator supply is relieved of responsibility of producing magnetic field synchronous motor has large air gap mechanical load on the motor can be adjusted synchronous motor runs at synchronous speed stator supply is relieved of responsibility of producing magnetic field synchronous motor has large air gap ANSWER DOWNLOAD EXAMIANS APP
