[0002] The segmented stator structure is widely used in fields with strict requirements on motor size and weight, such as automotive electric drive systems and aerospace. The traditional segmented stator core only has one pin fixed on the stator teeth. When the stator is wound or the motor is powered on, the stator core is subjected to mechanical or electromagnetic forces from all directions, causing the stator punchings to shift and resulting in various deformations of the core, which in turn affects the performance and stability of the motor.

A plurality of pin holes are opened on the stator punching sheet body, and there are three pin holes. The three pin holes are distributed on the stator punching sheet body in an equilateral triangle; the pins are correspondingly inserted into the plurality of pin holes to fasten the stator punching sheet body.
[0005] Furthermore, two pin holes are symmetrically opened on the yoke along the geometric center line of the stator punching body, and one pin hole is opened at the center line position of the tooth portion of the stator punching body.
[0006] The utility model discloses a block-type stator punching sheet for preventing iron core deformation, comprising a stator punching sheet body, a pin hole, and a pin. The stator punching sheet body is provided with a plurality of pin holes, and there are three pin holes, which are distributed on the stator punching sheet body in an equilateral triangle.

The exemplary embodiments of the present invention and their descriptions are provided to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0009] The above drawings include the following reference numerals:

[0011] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0012] According to an embodiment of the present invention, a block-type stator punching piece for preventing iron core deformation is provided. Figure 1 As shown, it includes: a stator punching body 10, a pin hole 11, and a pin 20. The stator punching body 10 is provided with a plurality of pin holes 11, and there are three pin holes 11. The three pin holes 11 are distributed on the stator punching body 10 in an equilateral triangle; the pins 20 are correspondingly inserted into the plurality of pin holes 11 to fasten the stator punching body 10. The multi-point fixed design greatly increases the overall stability of the stator structure. The fastened stator punching body 10 can effectively resist external shocks and vibrations, avoid deformation of the iron core due to loosening or displacement, and effectively prevent deformation of the stator due to uneven force or other external forces during operation. The triangle stability principle is used to effectively disperse concentrated stress points, reduce the risk of deformation of the punching sheet at the stress concentration location, and enable it to better resist mechanical fatigue and stress changes in long-term use during operation, thereby extending the service life of the stator punching sheet and enhancing the mechanical strength and stiffness of the stator core.
[0013] Further, if Figure 1 As shown, two pin holes 11 are symmetrically opened on the yoke along the geometric center line of the stator punching body 10, and one pin hole 11 is opened at the center line of the tooth part of the stator punching body 10. This layout not only makes the punching more evenly distributed when subjected to force, but also enhances the overall stress resistance of the stator and further reduces the risk of deformation.
[0014] The utility model discloses a block-type stator punching sheet for preventing iron core deformation. A plurality of pin holes 11 are opened on the stator punching sheet body 10. There are three pin holes 11, and the three pin holes 11 are distributed on the stator punching sheet body 10 in an equilateral triangle. Pins 20 are correspondingly inserted into the three pin holes 11 to fasten the stator punching sheet body 10. Combined with the symmetrical arrangement and the stability principle of the equilateral triangle, the overall stability and stress resistance of the stator structure are effectively improved, the external force is evenly dispersed, and deformation caused by loosening, displacement and stress concentration is prevented, thereby ensuring the stability and reliability of the stator during operation and extending its service life.
[0015] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
