Answer Posted / rahul
In induction motor power factor depends on air gap ,if air
gap more then power losses occured due inductive reactance
which lag power factor, power absorb by motor interms heat
increases. but in case of sych motor power factor depends on
stator exiatation,E>V POWER FACTOR LEAD.E<v then power factor
lag,so we have to maitain stator exiatation rather than the
air gap
