Synchronous Motors An important advantage of a synchronous motor over wound round induction motor is that its power factor may be varied at will its speed may be controlled more easily its speed is independent of supply frequency None of these its power factor may be varied at will its speed may be controlled more easily its speed is independent of supply frequency None of these ANSWER DOWNLOAD EXAMIANS APP
Synchronous Motors The power factor of a synchronous motor is better than that of induction motor because stator supply is relieved of responsibility of producing magnetic field mechanical load on the motor can be adjusted synchronous motor runs at synchronous speed synchronous motor has large air gap stator supply is relieved of responsibility of producing magnetic field mechanical load on the motor can be adjusted synchronous motor runs at synchronous speed synchronous motor has large air gap ANSWER DOWNLOAD EXAMIANS APP
