A three-phase squirrel cage motor was modeled to evaluate the impact of voltage imbalance on power factor of such type of motors. The model has been derived using a multi coupled circuits approach. Then a transformation called Hilbert transform was used to convert the input voltage and current into rotating vectors in order to determine the instantaneous power factor. The obtained results show that the power factor of the motor increases as the percentage of voltage imbalance increase.
