[0002] Electric motors are widely used in modern household appliances. For example, as a crucial component of compressors, they play a vital role in refrigerators, air conditioners, freezers, heat pump water heaters, and other cooling or heating appliances, influencing their power and heating efficiency. Currently, in motor design and manufacturing, insulating supports are a common component, mostly made of PBT or PPS material with smooth surfaces. During winding, the enameled wire slips at its winding points, causing significant discrepancies between the set winding parameters and the actual arrangement. This results in uneven distribution of the enameled wire within the winding slot. Furthermore, the high winding speed and tension can easily damage the enamel film at corners, leading to a decrease in the motor's winding quality. Therefore, there is an urgent need for an insulating support to address these problems. Utility Model Content

[0004] 1. An insulating support is provided, wherein an anti-slip platform is provided on the winding frame, and the anti-slip platform is provided with an anti-slip groove for fixing the position of the enameled wire, which can make the enameled wire stably arranged and reduce the risk of paint damage.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0039] like Figures 1 to 5 As shown, this utility model provides an insulating support, including a frame 1, a winding frame 2, and a winding guard wall 3. The frame 1 has a ring structure, and multiple winding frames 2 are evenly arranged along the circumference of the frame 1. A clearance notch is provided between adjacent winding frames 2 to allow the enameled wire to pass through. The winding frame 2 is provided with an anti-slip platform 21, the top surface of which is angled to the horizontal direction. The top surface of the anti-slip platform 21 is provided with a wavy anti-slip groove 22, which is used to fix the position of the enameled wire, enabling stable wire distribution, improving the winding condition of the enameled wire, and reducing the risk of enameled wire damage. Meanwhile, the winding guard wall 3 is located in the inner ring of the frame 1 and is connected to the winding frame 2. The winding guard wall 3 prevents the enameled wire from detaching from the winding frame 2. The winding guard wall can release space inside the frame, which is more conducive to the distribution of enameled wire and high slot fill rate models, effectively controlling the wire laying space.
[0040] For example, the width of the anti-slip groove 22 is less than or equal to half the width D of the anti-slip table 21, and / or the length of the anti-slip groove 22 is less than or equal to half the length L of the anti-slip table 21. This ensures the stability of the enameled wire arrangement while maintaining the strength of the anti-slip table 21 and the winding frame 2, preventing breakage of the winding frame 2 during winding and thus avoiding defective products. Specifically, the anti-slip groove 22 is positioned on the winding frame 2 at the starting position, either clockwise or counterclockwise, according to the winding direction. This ensures that the enameled wire first contacts the anti-slip groove 22 when winding through the winding frame 2, allowing for stable arrangement of the enameled wire and reducing the risk of paint damage.
[0041] Furthermore, the angle α between the top surface of the anti-slip table 21 and the horizontal direction satisfies 0°<α≤45°, which reduces the pressure and friction of the enameled wire on the corner of the winding part of the winding frame 2, thereby improving the winding state of the enameled wire. At the same time, it reduces the circumference of the enameled wire, reduces the amount of enameled wire used, and thus reduces production costs.
[0042] For example, the anti-slip groove 22 has a toothed cross-section. Specifically, the tooth tip h of the anti-slip groove 22 satisfies 0.5mm≤h≤2mm, and the tooth width d of the anti-slip groove 22 satisfies 0.5mm≤d≤5mm. This ensures that the anti-slip groove 22 can stably fix the position of the enameled wire while reducing the risk of paint damage. In addition, controlling the depth and width of the anti-slip groove 22 helps to control the strength of the winding frame 2 and avoid damage to the winding frame 2 during the winding process.
[0043] like Figure 3 As shown, the height of the top of the anti-slip table 21 is H1, the height of the lowest point of the top surface is H2, δ=H1-H2, and the difference δ between the highest and lowest points of the top surface of the anti-slip table 21 satisfies 0mm<δ≤15mm. By controlling the slope and height of the anti-slip table 21, the winding angle and circumference of the enameled wire can be effectively controlled, thereby reducing the winding circumference of the enameled wire while ensuring that the risk of paint damage is reduced.
[0044] For example, the winding guard wall 3 is provided with an observation opening 31, which is used to observe the wiring status of the enameled wire. In this embodiment, the observation opening 31 is an inverted triangle shape, and the top width D1 of the observation opening 31 is equivalent to the width D of the anti-slip table 21. During the winding process of the enameled wire, as the number of winding turns of the enameled wire increases, the probability of poor wiring increases. The observation opening 31 can effectively observe and check the wiring status of the enameled wire.
[0045] On the other hand, this utility model also provides an electric motor, which includes an insulating bracket. The motor is used to drive a compressor. The motor includes a stator, and the insulating bracket is disposed at both ends of the stator. The insulating bracket is used to fix the enameled wire winding. The insulating bracket with stable and uniform enameled wire winding can effectively improve the winding quality of the stator, thereby improving the insulation performance and stability of the motor to meet the higher usage requirements of the compressor.
[0046] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
