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
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 small the stator current will be very high the back e.m.f. will be more than the supply voltage the stator current will be zero the stator current will be very small the stator current will be very high the back e.m.f. will be more than the supply voltage the stator current will be zero ANSWER DOWNLOAD EXAMIANS APP
