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. The invention increases the frequency of the non-short-circuit phase winding current when a short-circuit fault occurs in the permanent magnet generator, thereby generating a high-order harmonic magnetic field inside the permanent magnet. By increasing the frequency of the normal phase winding current, the eddy current loss of the permanent magnet is significantly increased, causing the permanent magnet to rapidly heat up in a short time, resulting in irreversible demagnetization. This weakens the air gap magnetic field, thus suppressing the short-circuit current. Therefore, it is possible to achieve dynamic control of the temperature rise rate and suppress damaging demagnetization while minimizing the increase in the complexity of the motor itself.
