Resolution A lagging power factor denotes that on the phasor diagram, the current lags … Web10 apr. 2024 · The induction motor power factor mainly changes with load, normally at full load it is approximately 0.85 or 0.90 and at no load, it is about 0.20. An induction motor at no load draws a large magnetizing current & a small active component to reach the no-load losses. So the induction motor’s power factor on no load condition is low.
