What is the power factor of induction motor at full load and no load?
The power factor of induction motors varies with load, typically from around 0.85 or 0.90 at full load to as low as about 0.20 at no-load.
At no load, an induction motor draws a large magnetizing current and a small active component to meet the no-load losses.
Therefore, the induction motor takes a high no-load current lagging the applied voltage by a large angle.
Hence the power factor of an induction motor on no load is low.
