[0002] Existing motors and engines, such as motors for automobiles and ships, are the reason for the power change output during operation. The speed and torque are usually in a nonlinear relationship, and high speed and high torque cannot be achieved at the same time. Insufficient power, unable to meet the requirements of use, and when a car needs a high torque when passing a pit or climbing a slope, because the high torque output of the car is not at a high speed moment, it is difficult to grasp when the high torque output can be obtained, and the control is difficult Generators such as wind power generators, in order to output constant frequency electric energy under different wind speeds, usually use double-fed asynchronous generators. The rotor winding of the generator is connected to the power converter through slip rings and brushes, and the power converter is used to perform frequency compensation for different rotor frequencies, so as to finally output electric energy with a constant frequency. Since there are brushes in the double-fed guided step generator, As a brushed motor, it inevitably brings friction loss, increases maintenance and noise, and has a short service life

In addition, motors such as motors for aviation aircraft and brushless AC motors are likely to cause damage to the electronic control system due to the large current and high voltage output power supply. Therefore, most of the existing motors for aviation aircraft still use brushed DC motors, but they still The short life of the brushed DC motor and the defects of sparks are left
