Synchronous Motors Dust and dirt accumulation on motor winding will result in Increased core losses Shorting of coils Rise in winding temperature Eddy current flow Increased core losses Shorting of coils Rise in winding temperature Eddy current flow ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors If the field circuit of an unloaded salientpole synchronous motor gets suddenly open-circuited, then 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 the motor stops it runs at a slower speed it continues to run at the same speed ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors The power factor of a synchronous motor is better than that of induction motor because synchronous motor has large air gap mechanical load on the motor can be adjusted stator supply is relieved of responsibility of producing magnetic field synchronous motor runs at synchronous speed synchronous motor has large air gap mechanical load on the motor can be adjusted stator supply is relieved of responsibility of producing magnetic field synchronous motor runs at synchronous speed ANSWER DOWNLOAD EXAMIANS APP
