[0022] The stator base 03 supports the ground terminal 01 and multiple stator cores 02 respectively, so that the ground terminal 01 and multiple stator cores 02 can maintain stability during operation. The ground terminal 01 can be directly connected to the silicon steel sheet by press-fitting, and the strain of the terminal is maintained by setting a special structure. In order to protect the components on the PCB from being damaged by static electricity and to facilitate the measurement of the insulation characteristics between the stator core 02 and the winding, the motor stator silicon steel sheet is usually connected to one end of the terminal, and the other end is led out to connect to the connector or PCB, thereby improving the practicality of the equipment.

[0023] Preferably, the ground terminal 01 includes a mounting hole 11, a shuttle-shaped slot 12 and a plurality of ribs 13. The ground terminal 01 is provided with a mounting hole 11 and a shuttle-shaped slot 12, and the plurality of ribs 13 are respectively installed on the shuttle-shaped slot 12;

[0024] Preferably, the ground terminal 01 is open in shape, and a shuttle-shaped slot 12 is provided inside, and the shuttle-shaped slot 12 is in the shape of a shuttle;

[0025] Preferably, a plurality of ribs 13 are provided in the shuttle-shaped groove 12, and the plurality of ribs 13 are formed by respectively stamping and then bending;

[0026] The grounding terminal 01 is installed on the stator base 03 through the mounting hole 11. Multiple ribs 13 support the shuttle slot 12 respectively. The grounding terminal 01 ensures that its press-in type has sufficient elastic stress. Increasing the elastic stress can increase the contact resistance between the terminal and the silicon steel sheet, thereby better increasing its conductivity. After being pressed in, the terminal undergoes elastic deformation in the planar direction and has a clearance fit in the normal direction of the plane. After the grounding terminal 01 is pressed in, multiple ribs 13 undergo elastic deformation at the same time, increasing the stress and, at the same time, improving the resistance to creep and improving the practicality of the equipment.

[0027] Example 2

[0028] On the basis of Example 1, it further includes a plurality of stator cores 02, each of which is formed by alternately stacking a plurality of silicon steel sheets. The plurality of silicon steel sheets are stacked on the positioning ribs and tightened into a whole by upper and lower tooth pressure plates and tension bolts.

[0029] The multiple stator cores 02 each play the role of magnetic circuit conduction, helping to convert electrical energy into mechanical energy. When current passes through the stator coil, the multiple stator cores 02 each generate a magnetic field, forming an action force between the rotating rotor poles, pushing the rotor to rotate, and improving the practicality of the equipment.

[0032] The stator base 03 is the stationary part of the motor or linear transmission system, used to support and fix key components such as the stator core and stator winding to improve the practicality of the equipment.

[0033] like Figures 1 to 5As shown, a grounding terminal connection structure of the present invention, when working, first the grounding terminal 01 is installed on the stator base 03 through the mounting hole 11, and multiple ribs 13 respectively support the slots of the shuttle slot 12, and then the grounding terminal 01 ensures that its press-in type has sufficient elastic stress. Increasing the elastic stress can increase the contact resistance between the terminal and the silicon steel sheet, thereby better increasing its conductivity. After pressing in, the terminal undergoes elastic deformation in the plane direction and has a clearance fit in the plane normal direction. After that, after the grounding terminal 01 is pressed in, multiple ribs 13 undergo elastic deformation at the same time, increasing the stress and, at the same time, improving the resistance to creep. Then the stator core 02 plays a role in magnetic circuit conduction, helping to convert electrical energy into mechanical energy. When current passes through the stator coil, the stator core 02 generates a magnetic field, which forms a force with the rotating rotor poles to drive the rotor to rotate. Finally, the stator base 03 is the stationary part of the motor or linear transmission system, used to support and fix key components such as the stator core and stator winding, thereby improving the practicality of the equipment.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
