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