[0007] In some embodiments, the second ventilation groove includes a plurality of them, which are evenly distributed at the four corners of the punching sheet body.
[0008] In some embodiments, both the first ventilation groove and the second ventilation groove adopt a closed-loop ventilation groove hole structure.

[0020] Such as Figure 1As shown, an inorganic shell servo motor punching sheet with high strength and good heat dissipation includes a punching sheet body. The punching sheet body is provided with a first ventilation groove 1, a screw hole 2, a second ventilation groove 3, a pin hole 4, and a coil groove 5. The coil groove 5 is circumferentially arranged in the center, and the first ventilation groove 1, the screw hole 2, the second ventilation groove 3, and the pin hole 4 are respectively circumferentially arranged outside the coil groove 5.
[0021] The inorganic shell servo motor punching sheet of the present utility model adopts an integrated structure design, without the motor structure of an independent casing. The outer shape of the inorganic shell servo motor punching sheet is square, and the structure is stable;
[0022] The stator is axially laminated by a plurality of punching sheets to a required height. When the motor is assembled, end covers are installed at both ends of the stator, and the rotor is supported in the center of the stator through bearings. An independent fan is arranged at the non-axis end of the motor, which drives gas to dissipate heat through the stator ventilation groove during operation, and the heat dissipation effect is good. Embodiment
[0023] As Figure 1 shown, an inorganic shell servo motor punching sheet with high strength and good heat dissipation includes a punching sheet body. The punching sheet body is provided with a first ventilation groove 1, a screw hole 2, a second ventilation groove 3, a pin hole 4, and a coil groove 5. The coil groove 5 is circumferentially arranged in the center, and the first ventilation groove 1, the screw hole 2, the second ventilation groove 3, and the pin hole 4 are respectively circumferentially arranged outside the coil groove 5.
[0024] In this embodiment, the shape of the punching sheet body is a square structure. The punching sheet body adopts a square structure similar to the motor housing, thereby enhancing the overall stability and strength of the punching sheet.
[0025] In this embodiment, as Figure 1 shown, each group of the first ventilation grooves 1 includes two irregular strip-shaped holes, and the holes are evenly distributed on the four sides of the punching sheet body, a total of eight.
[0026] In this embodiment, as Figure 1 shown, each group of the second ventilation grooves 3 includes six irregular strip-shaped holes, and they are evenly distributed at the four corners of the punching sheet body, a total of 24.
[0027] In this embodiment, as Figure 1 shown, both the first ventilation groove 1 and the second ventilation groove 3 adopt a closed-loop ventilation groove hole structure. The closed-loop groove hole structure has a large heat dissipation area, and the airflow of the motor cooling fan flowing forward in the ventilation groove has strong heat dissipation ability. In addition, because the stator is directly exposed to the external environment, the outer surface of the stator also has a certain heat dissipation ability, forming a dual heat dissipation function.
[0028] In this embodiment, as Figure 1As shown, the screw holes 2 are located between the first ventilation groove 1 and the second ventilation groove 3, and are evenly distributed on the four sides of the punching sheet body, with 2 provided on each side. The screw holes 2 are matched with the screws. There are 8 evenly distributed screw holes arranged in the four-side direction of the punching sheet. When assembling the end cover, the screws pass through the rear cover and penetrate the stator and are screwed into the front cover, connecting the end cover and the stator into one body.
[0029] In this embodiment, as Figure 1 shown, the pin holes 4 are evenly distributed at the four corners of the punching sheet body, located inside the second ventilation groove 3, with a total of 4. The pin holes 4 are matched with the pin rods. There are 4 evenly distributed pin holes arranged in the four-corner direction of the punching sheet. When laminating the punching sheets, the pin rods are inserted, which can prevent adverse factors such as misalignment and deformation of the overall stator. The pin rods can also protrude a certain length from the stator to cooperate with the hole positions on the end cover, ensuring good assembly positioning accuracy between the end cover and the stator, and also ensuring that the end cover and the stator will not undergo radial torsion during the operation of the motor.
[0030] The shell-less servo motor in the present utility model is a motor structure that does not require an independent motor shell. Its punching sheet is provided with functional structures originally belonging to the motor shell, such as ventilation grooves, end cover installation positions, and protective frames, outside the magnetic flux range. The outer shape of the shell-less servo motor punching sheet is generally square. The stator is axially laminated by several punching sheets to the required height. When assembling the motor, end covers are installed at both ends of the stator, and the rotor is supported at the center of the stator through bearings. An independent fan is provided at the non-shaft end of the motor, which drives the gas to dissipate heat through the stator ventilation grooves during operation.
[0031] The above is only a preferred embodiment of the present utility model, and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, may make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
