[0002] The motor consists of two parts: the rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into two types: inner rotor rotation mode and outer rotor rotation mode. The inner rotor rotation mode is that the core in the middle of the motor is a rotating body, outputting torque or receiving energy. The outer rotor rotation mode is that the outer body of the motor is a rotating body. Different modes facilitate the application of various occasions.
