    The magnetic flux flowing in the stator and rotor is alternating in nature and this demands the constant process of magnetic reversal in the steels.

    The work done by the magnetizing force against the internal friction of steels to reverse its magnetization produces heat. The energy which is spent in this process is wasted as heat. This is called hysteresis loss.
