Description
Technical Field
[0001] The utility model relates to the technical field of rotors, in particular to a carbon fiber sleeve structure of a rotor. Background Art
[0002] The rotor is the rotating part of the motor. 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 the rotating body, outputting torque (referring to the motor) or receiving energy (referring to the generator). The outer rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application of various occasions.
[0003] However, when the existing carbon fiber sleeve structure of the rotor is used, the strength of the outer shell of the rotor is low and the installation is inconvenient, which has a certain impact on the protection effect of the rotor. At the same time, the rotor will generate heat when working. If the heat is not dissipated in time, it will have a certain impact on the service life of the rotor. Therefore, a carbon fiber sleeve structure of the rotor is provided. Utility Model Content
