The servo motor itself mainly consists of a stator and a rotor. The stator generates a rotating magnetic field, and the rotor rotates synchronously under the action of the magnetic field to realize the rotation of the motor. It is widely used in fields that require precise control of angles, speeds, and positions;

The main function of the stator is to generate a rotating magnetic field, and the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate current. The two work together. The stator mainly relies on the stator core and the stator winding to work together. When winding the winding, if its positioning is unstable and the winding slips, it is likely to directly affect the normal winding of the winding. Moreover, it needs to be externally connected. If its position is not well positioned, it is also likely to affect the subsequent positioning connection effect. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a stator structure of a servo motor to solve the problems raised in the above background technique that the stator mainly relies on the stator core and the stator winding to work together. When winding the winding, if its positioning is unstable and the winding slips, it is likely to directly affect the normal winding of the winding. Moreover, it needs to be externally connected. If its position is not well positioned, it is also likely to affect the subsequent positioning connection effect.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A stator structure of a servo motor includes a stator core and stator tooth poles.

[0014] (1) By evenly distributing the stator tooth poles at the inner wall position of the stator core, and a groove body is formed under the distribution of the stator tooth poles, the groove body facilitates the coil winding. Then, grooves are evenly distributed outside the stator tooth poles. Therefore, the grooves can limit and position the coil winding, reduce the phenomenon of falling off. At the same time, a reserved groove is distributed outside the stator core. After being connected with the arc-shaped block through the reserved groove, the connection and fixation with the connecting block can be completed under the connection of the connecting block.

The first reinforcing rod and the second reinforcing rod are matched to form support and reinforcement. Then, two sets of connecting rods are distributed between the first reinforcing rod and the second reinforcing rod for connection and reinforcement. In this way, the overall use strength is better improved during the working process;

[0016] (3) By coating the protective layer on the outer wall of the stator core, and the protective layer is composed of a wear-resistant layer and an anti-corrosion layer. Therefore, the anti-corrosion layer is coated on the outer wall of the stator core for anti-corrosion protection, and the wear-resistant layer is coated on the outside of the anti-corrosion layer. So, after the wear-resistant layer is coated, it is located on the outermost side, forming a certain wear protection. Therefore, during the working process, the overall protection ability is improved preferably. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] There are two groups of guide rail blocks 9 distributed at the top of the connecting block 7, and the guide rail blocks 9 are symmetrically distributed about the central axis of the connecting block 7.

[0027] The stator tooth poles 2 are distributed annularly about the center of the stator core 1, and the grooves 4 are evenly distributed outside the stator tooth poles 2.
