Answer Posted / nitin banegaon
its sooo simlpe. when induction motor is on load then the no load current will have two components one is active/load component and other magnetizing component. Magnetizing component is for creating magnetic field to spin the motor which is independent of load current and it lags behind the voltage by 90. Initially on load, current is so small which is normally is in phase with applied voltage. So on no load circuit is inductive. So power factor is small nearly 0.2 to 0.4.
