[0021] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.
[0022] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0023] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0024] This specific embodiment is an insulation impregnation motor stator, such as Figure 1 As shown, the insulation impregnated motor stator 2 includes a motor body 1, to which the motor stator 2 is fixedly connected; a guide assembly, which is used to assist the user in installing the insulating paper 4 on the wire core slot 3. The guide assembly is connected to the motor stator 2. By setting the guide assembly, the contact surfaces of the insulating paper 4 and the wire core slot 3 cooperate with each other. Through multiple mutually cooperating structures, it is ensured that the insulating paper 4 does not move in the wire core slot 3, thereby ensuring the motor performance.
[0025] Reference Figure 2 、 Figure 3 and Figure 4 As shown, the guide assembly includes core slots 3 evenly opened on the inner wall of the motor stator 2, and insulating paper 4 is slidably inserted into the core slots 3. When manually inserting the insulating paper 4, the insulating paper 4 needs to be inserted into the core slots 3 one by one, and the positions of the insulating paper 4 and the core slots 3 must be stable. A guide groove 301 is opened on the inner wall of the core slot 3, and then matched with the arc segment 401 of the insulating paper 4. The two complement each other. By setting the guide assembly, the guide groove 301 cooperates with the arc segment 401 at the center of the insulating paper 4 to guide the insulating paper 4.
[0026] Reference Figure 2 、 Figure 3 and Figure 4 As shown, the top end of the core slot 3 is open, a guide groove 301 is provided at the center of one end of the bottom inner wall of the core slot 3, oblique grooves 302 are symmetrically provided at both ends of the core slot 3, and limiting grooves 303 are symmetrically provided on both sides of the top inner wall of the core slot 3. The cross-section of the core slot 3 is a trapezoidal shape with a narrow top and a wide bottom. The insulating paper 4 passes through one end of the core slot 3. By symmetrically providing oblique grooves 302 at both ends of the core slot 3, the openings at both ends of the core slot 3 are enlarged, which facilitates the quick insertion of the insulating paper 4 into the core slot 3. When pinching the insulating paper 4 by hand to insert it into the core slot 3, the arc section 401 of the insulating paper 4 is aligned with the guide groove 301 of the core slot 3 and inserted inward, so as to facilitate the accurate insertion of the insulating paper 4 into the core slot 3.
[0027] Reference Figure 2 、 Figure 3 and Figure 4As shown, the central section of the insulating paper 4 is provided with an arc section 401, which is adapted to the guide groove 301. Folding sections 402 are symmetrically connected on both sides of the arc section 401. The cross section of the folding section 402 is a multi-segment M-shape. Flanging edges 403 are provided at both ends of the folding section 402. The cross section of the flanging edge 403 is V-shaped, and the flanging edge 403 is adapted to the size of the limiting groove 303. The arc section 401 of the insulating paper 4 is aligned with the guide groove 301 and inserted inward, ensuring that the relative position of the insulating paper 4 and the core notch 3 is stable. By providing the folding sections 402 on both sides of the insulating paper 4, the tension distribution of the insulating paper 4 is changed by folding, thereby increasing the stability and bearing capacity of the insulating paper 4. The limiting groove 303 cooperates with the flanging edges 403 at both ends of the insulating paper 4 to limit the relative position of the insulating paper 4 and the core notch 3, so that the insulating paper 4 does not move, thereby ensuring that the motor performance is not affected.
[0028] Working principle:
[0029] When the insulating paper 4 is inserted into the core slot 3, first hold one side of the insulating paper 4 and bring the two ends of the insulating paper 4 close together to facilitate smooth insertion into the core slot 3, so that the arc section 401 of the insulating paper 4 is inserted inward along the guide groove 301. When most of the insulating paper 4 is inserted, the tension of the insulating paper 4 itself is used to approach the inner wall of the core slot 3. Since folding sections 402 are provided on both sides of the insulating paper 4, the insulating paper 4 can be maintained in the state of the inner wall of the core slot 3. Release your fingers, and the flanges 403 at both ends of the insulating paper 4 cooperate with the limiting grooves 303 of the core slot 3, further stabilizing the state of the insulating paper 4 until the insulating paper 4 is completely inserted into the core slot 3. The insulating paper 4 is limited by the structural cooperation at multiple locations so that the insulating paper 4 does not move, thereby ensuring that the motor performance is not affected.
