Synchronous Motors The standard full-load power factor ratings for synchronous motors are zero or 0.8 leading unity or 0.8 leading unity or 0.8 lagging unity or zero zero or 0.8 leading unity or 0.8 leading unity or 0.8 lagging unity or zero 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 zero the stator current will be very high the stator current will be very small the back e.m.f. will be more than the supply voltage the stator current will be zero the stator current will be very high the stator current will be very small the back e.m.f. will be more than the supply voltage ANSWER DOWNLOAD EXAMIANS APP
