[0002] A stepper motor is a type of electric motor that has unique motion control characteristics. It is widely used in many applications because it enables precise position control and reliable motion. The basic structure of a stepper motor includes a stator, a rotor, and a drive circuit. The stator consists of magnets, usually divided into two or more pole pairs. The rotor is the rotating part of the motor, usually composed of a group of magnets or magnetic materials. The drive circuit is used to control the flow of current through the stator, thereby causing the movement of the rotor;

[0003] The shell is an indispensable structure that covers the outside of the stepper motor and supports the main structure of the stepper motor. Most of the existing stepper motor shells are an integral metal shell, which is directly mounted on the stator structure of the stepper motor. Due to installation reasons, there will be a certain gap between the shell and the stator structure of the stepper motor. This gap will affect the heat conduction of the stator structure after the stator structure is installed, so the service life of the stepper motor will also be affected. Utility Model Content

[0004] The purpose of the utility model is to overcome the defect that most of the stepper motor shells in the prior art are an integral metal shell, which is directly sleeved on the stator structure of the stepper motor. Due to the need to consider installation reasons, there will be a certain gap between the shell and the stator structure of the stepper motor. This gap will affect the heat conduction of the stator structure after the stator structure is installed, so the service life of the stepper motor will also be affected. A heat dissipation shell for a motorcycle stepper motor is provided. The device is sleeved on the outside of the stator structure of the stepper motor. On the one hand, it plays a role of supporting the main structure, and on the other hand, it plays a role of auxiliary heat dissipation.

In the device, a cavity is arranged between the heat conductive inner sleeve and the inner wall of the outer shell body, and the cavity is filled with heat conductive silicone. At the same time, a plurality of guide holes are arranged on the inner wall of the heat conductive inner sleeve, so that when the heat conductive inner sleeve is sleeved with the stator structure of the stepper motor, the heat conductive silicone in the cavity can penetrate into between the heat conductive inner sleeve and the stator structure of the stepper motor through the guide holes, ensuring that the heat conductive inner sleeve and the stator structure of the stepper motor fit closely, thereby further improving the heat conduction speed of the stator structure of the stepper motor and improving the service life of the stepper motor.

[0008] Preferably, each independent space region in the cavity corresponds to each group of guide holes one by one, so that it can be ensured that the thermal conductive silica gel in the cavity permeates outward more evenly.

[0009] Preferably, a sealing ring is embedded in the inner wall of the heat-conductive inner sleeve and located at the edge of the heat-conductive inner sleeve, so as to increase the sealing performance of the heat-conductive inner sleeve after installation, thereby avoiding leakage of heat-conductive silicone.
