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 electric motor rotor and generator rotor. 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 the rotating body, outputting torque or inputting energy. The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate application in various occasions.
