Synchrounous motor is three phase motor,but its not self
starting .why?
Answer Posted / vikash kumar gaurav
similar pole are alike each other it is a three phase motor
bt very low starting torque and the average exerted torque
in operation of synchronous motor is zero and we have to
supply both the rotor and stator this is another cause it
is nt aself starting machine.

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
