The permanent magnet motor has the advantages of high efficiency, high power density, large power factor, large starting torque, wide speed regulation range and the like, and has gradually replaced induction motors and switched reluctance motors, so that the permanent magnet motor is increasingly widely applied in various fields of industrial production and daily life. Because of the demand for miniaturization of the external shape, the generator set with the structure generally does not have a cooling fan, but only cools the generator by freely circulating air in the case, and the generator set with the structure cannot continuously operate for a long time. Since the generator is not directly cooled, the heat generated by the stator coil cannot be quickly discharged, so that the temperature rise of the rotor with the permanent magnets is also quickly increased. For permanent magnet generators, temperature is a direct factor in determining the performance of the permanent magnets. Therefore, the control of the temperature is a problem to be solved in order to make the performance of the permanent magnet relatively stable and reduce irreversible changes during application.
