This invention discloses a temperature-controlled demagnetization method for a permanent magnet generator used in small aircraft, relating to the fields of motor fault tolerance and short-circuit current suppression. It achieves dynamic control of the temperature rise rate and suppresses damaging demagnetization while minimizing the increase in the complexity of the motor itself.
