[0002] Motor rotor: It is also the rotating part in the motor. The motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa.

[0003] There are two types of motor rotors: inner rotor rotation and outer rotor rotation. In the inner rotor rotation, the core in the middle of the motor is the rotating body, outputting torque (referring to the motor) or receiving energy (referring to the generator). In the outer rotor rotation, the outer body of the motor is the rotating body. Different methods facilitate the application of various occasions.

[0004] The motor rotor consists of a cylinder with grooves and a coil wound inside the grooves.

Since the fixing direction is from the inside to the outside, there is no external structure outside the motor rotor, which is more convenient for processing the outer surface, meeting the requirements of the processing procedure.

[0017] 3. In the utility model, one side of the fixing disk can be unscrewed, the motor rotor can be passed through the shaft body, and then the motor rotor can be fixed with the internal fixing structure; then the two fixing disks are rotated inward, and the fixing disks are rotated inward from the outside of the threaded part to the inside, pressing the two sides of the motor rotor, further locking the motor rotor, so that the fixation of the motor rotor and the shaft body is more stable, which is beneficial to the synchronization of the subsequent driven rotation.
