[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 external structure of the stepper motor is mainly composed of an outer shell as the main structure and a tail shell connected to the external connection (such as a connector). In the existing stepper motor, the tail shell is directly mounted on the tail end of the outer shell, and there is a lack of insulation support between the two. Therefore, there are certain safety hazards at the connection position, and as the motor runs, gaps are prone to appear at the connection position, resulting in a decrease in the overall sealing of the motor. Utility Model Content
