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
