Rare earth permanent magnet motors (REPM) are mainly used in various electric systems of aircraft. Electric braking system is a driving system with motor as its actuator. It is widely used in aircraft flight control system, environmental control system, braking system, fuel and starting system.

Due to the excellent magnetic properties of rare earth permanent magnets, a strong permanent magnetic field can be established without additional energy after magnetization. The rare earth permanent magnet motor made by replacing the electric field of the traditional motor is not only efficient, but also simple in structure, reliable in operation, small in size and light in weight. It can not only achieve the high performance that traditional excitation motors cannot achieve (such as ultra-high efficiency, ultra-high speed, ultra-high response speed), but also produce special motors that meet specific operating requirements, such as elevator traction motors, special motors for automobiles, etc.
