[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: a motor silicon steel sheet that is easy to assemble, comprising a silicon steel disk 1, silicon steel sheets 3 are fixedly installed on all four sides of the surface of the silicon steel disk 1, and a silicon steel strip 4 is fixedly installed at one end of the silicon steel sheet 3. The silicon steel strip 4 is arc-shaped, and there are five sets of silicon steel sheets 3 and silicon steel strips 4. The five sets of silicon steel sheets 3 and silicon steel strips 4 are arranged in an equidistant circular pattern on the surface of the silicon steel disk 1. A circular hole 10 is opened in the middle of the silicon steel disk 1, and rectangular... The mounting shaft 5 is movably installed inside the groove 12 and the circular hole 10. The connecting plates 8 are fixedly installed on both the front and rear sides of the mounting shaft 5. The movable blocks 6 are movably installed on both the upper and lower sides of the surface of the mounting shaft 5. The movable block 6 has a limit hole 13 in the middle. The limit hole 13 has a limit groove 14 on both the front and rear sides. The mounting screw 7 is threaded on one side of the movable block 6. The circular hole 10 and the limit hole 13 are exactly the same in size and shape. The rectangular groove 12 and the limit groove 14 are exactly the same in size and shape.

[0022] After stacking multiple silicon steel sheets 3, the circular hole 10 and rectangular groove 12 in the middle of the silicon steel disc 1 can be aligned with the corresponding mounting shaft 5 and connecting plate 8. Then, the stacked silicon steel sheets 3 are placed on the surface of the mounting shaft 5. Next, the upper and lower movable blocks 6 are respectively placed on the upper and lower sides of the surface of the mounting shaft 5, so that the limiting hole 13 and limiting groove 14 can be aligned with the mounting shaft 5 and connecting plate 8. Then, the mounting screw 7 is tightened so that one end of the mounting screw 7 can abut against one side of the connecting plate 8, so that the movable block 6 can be fixed on the surface of the mounting shaft 5. This clamps and fixes the stacked silicon steel sheets 3 between the two movable blocks 6. The connecting plate 8, rectangular groove 12 and limiting groove 14 prevent the stacked silicon steel sheets 3 from rotating on the surface of the mounting shaft 5, which is conducive to the assembly of the stacked motor silicon steel sheets and increases the convenience of device installation. For the first heat dissipation hole 2 The arrangement of the first heat dissipation hole 2, being elliptical and arranged circumferentially on the surface of the silicon steel strip 4, facilitates better heat dissipation for the silicon steel strip 4. Similarly, the arrangement of the second heat dissipation hole 11, linearly arranged on the surface of the silicon steel sheet 3, facilitates better heat dissipation for the silicon steel strip 3, thus improving the heat dissipation effect of the device. The arrangement of the mounting pads 9, circumferentially arranged at the top and bottom of the silicon steel disk 1, creates gaps between the stacked silicon steel sheets 3, allowing air to flow through these gaps and further enhancing the heat dissipation effect of the device. The galvanized layer on the surfaces of the silicon steel disk 1, silicon steel sheet 3, silicon steel strip 4, mounting shaft 5, movable frame 6, connecting plate 8, limiting hole 13, and limiting groove 14 prevents corrosion and extends the service life of the device.

[0023] In one aspect of this embodiment, the arrangement of the first heat dissipation hole 2, and the fact that the first heat dissipation hole 2 is elliptical and that multiple first heat dissipation holes 2 are arranged circumferentially on the surface of the silicon steel strip 4, facilitates better heat dissipation of the silicon steel strip 4. Similarly, the arrangement of the second heat dissipation hole 11, and the fact that multiple second heat dissipation holes 11 are arranged linearly on the surface of the silicon steel sheet 3, facilitates better heat dissipation of the silicon steel strip 3, thereby improving the heat dissipation effect of the device.

[0024] In one aspect of this embodiment, regarding the arrangement of the mounting pads 9, since multiple mounting pads 9 are arranged circumferentially on the top and bottom of the silicon steel disc 1, gaps exist between the stacked silicon steel sheets 3, which facilitates airflow through the gaps and further enhances the heat dissipation effect of the device. Furthermore, the galvanized layer provided on the surfaces of the silicon steel disc 1, silicon steel sheets 3, silicon steel strips 4, mounting shaft 5, movable frame 6, connecting plate 8, limiting hole 13, and limiting groove 14 makes the device less prone to corrosion, thus extending the service life of the device.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
