Why the airgap of an induction motor is less compared to
that of a synchronous machine?
Answer Posted / arunkumar
as the stability critera is main in the synchronous m/c
the air gap length is more even though size and weight
increases with redused power factor ,where as there is no
stability criteria to be satisfied in I/M more
concentration is taken for power factor inprovement by
providing less air gap

I have doubt that the supply HZ (very low or high than rated ) may affect the power factor. is it true. ?
for 100 HP Induction motor service factor is 1.2(SF) we placed a VFD at the motor side load is balance with 0.3 Amp's Phase to Phase but at incoming of VFD load is un-balance with 10 to 20 Amp's what will be cause of load un balance
