[0002] The motor stator is an important component of motors such as generators and starters. The main function of the stator is to generate a rotating magnetic field. The stator is composed of three parts: a stator core, a stator winding, and a frame, and the stator core is formed by stacking and combining multiple silicon steel sheets.
[0003] During the processing of existing stator silicon steel sheets, most of them are blanked from a whole silicon steel sheet to obtain a complete stator silicon steel sheet. The stator silicon steel sheet is usually in a circular ring shape, and more materials will be cut off during processing, which is a waste of silicon steel sheet materials and leads to the problem of increasing the production cost of stator silicon steel sheets.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a stator silicon steel sheet structure. Content of the Utility Model
[0005] The purpose of the utility model is to provide a stator silicon steel sheet structure to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A stator silicon steel sheet structure includes a stator punching sheet and a splicing component. A wire groove is opened on one side of the stator punching sheet, and a limiting groove is opened on the other side of the stator punching sheet. The splicing component is arranged at both ends of the stator punching sheet. The splicing component includes a clamping part, a clamping groove, an avoidance groove, and an extension groove. A clamping part is arranged at one end of the stator punching sheet, and a clamping groove is opened at the other end of the stator punching sheet. An avoidance groove is arranged in the middle of the wire groove, and an extension groove is opened on the other side of the stator punching sheet.
[0007] Further, the limiting groove is arc-shaped, and the radius of the limiting groove is 1.5 mm.
[0008] Further, the shape of the clamping part coincides with that of the clamping groove, and the clamping groove is isosceles trapezoidal.
[0009] Further, the width of the clamping part is 5 mm, and the angle between the two hypotenuses of the clamping part is 30 degrees.
[0010] Further, the extension groove is arc-shaped, and the extension grooves are equidistantly distributed about the top of the stator punching sheet.
[0011] Further, the avoidance groove is keyhole-shaped, and the avoidance groove corresponds to the extension groove one by one.
[0012] Further, riveting components are arranged on both sides of the stator punching sheet. The riveting components include a riveting concave part and a riveting convex part. A riveting concave part is formed on one side of the stator punching sheet, and a riveting convex part is arranged on the other side of the stator punching sheet.
[0013] Further, the length of the riveting concave part is 3 mm, and the width of the riveting concave part is 1 mm.
[0014] The utility model provides a stator silicon steel sheet structure, which has the following beneficial effects:
[0015] 1. Through the arrangement of the avoidance groove and the extension groove, the stator punching sheet can have a certain bending deformation space, which is convenient for subsequent assembly into an annular silicon steel sheet. Therefore, in the process of blanking and processing the stator silicon steel sheet, through the segmented design, the stator punching sheet can be densely arranged on the whole silicon steel sheet material, reducing the wasted space on the silicon steel sheet material, thereby reducing the material cost, improving the production efficiency, and the processing is also simple and convenient;
