why induction motors are of lagging type and not leading
type
Answer Posted / iamdon
Induction motor is a singly excited machine.It means there
is no scope of power variation by varying the excitation.So
the nature of power factor is solely decided by the nature
of winding,which is moslty inductive.Thats why Induction
motor has always lagging power factor.
