  • Influence of variable frequency drive on motor winding temperature rise

    Induction motors may heat up more when fed by variable frequency drive (VFD) than when fed by sinusoidal supply. This higher temperature rise results from the motor losses growth owing to the high frequency components of the PWM signal and the often reduced heat transfer resulting from speed variation. The voltage harmonic distortion contributes to increase the motor ...
