The induction motor has the advantages of simple structure, no need of an electric brush and a commutator, strong carrying capacity and high reliability, and is widely applied in various fields, but the induction motor is relatively complex to control, and meanwhile, the efficiency and the power factor are low, so that the induction motor is not suitable for high-power occasions. The traditional permanent magnet brushless motor has the advantages of no brush, high efficiency and high power factor, but the permanent magnet is easy to demagnetize due to the influence of high temperature, which seriously affects the service life of the motor. In addition, the permanent magnet is adopted for excitation, excitation of the motor is inconvenient to adjust, weak magnetic control is not facilitated, and application of the permanent magnet brushless motor in the high-speed field is further limited.
