Description

TECHNICAL FIELD

[0001] The utility model relates to motor manufacturing technical field especially relates to a motor winding framework. BACKGROUND

[0002] In the motor production process, the winding framework is an important component to bear the winding coil. The traditional motor winding framework has many deficiencies. Some winding framework structures are simple, and the coils cannot be effectively limited and positioned during the winding process, which causes the coils to be easily loose and displaced, affecting the electrical performance and stability of the motor. Moreover, the compatibility of the traditional winding framework with other components of the motor is poor, and problems such as loose fit and inaccurate positioning may occur during the installation process, increasing the difficulty and cost of motor assembly. In addition, for some special motor designs, such as motors that need to integrate diodes and other electronic components, the traditional winding framework cannot provide suitable installation structures and spaces, limiting the expansion and optimization of motor functions. Therefore, it is of great significance to develop a new type of motor winding framework. SUMMARY

[0003] The utility model aims at providing a winding and positioning for motor winding, a motor winding framework that plays a key role in protecting motor performance and improving motor production efficiency and quality, to solve the above technical problems.

[0004] To achieve the above technical scheme, the technical scheme of the utility model is as follows: a motor winding framework is mainly composed of a body. The body is annular and has a thickness of 3mm. A circular array of V-shaped grooves is provided on the circumference of the body. These V-shaped grooves are the main parts for winding coils. A first protruding part is provided on one side of the circular array of the body, and a second protruding part is provided radially inward on the inner side of the body. The provision of the first and second protruding parts endows the winding framework with more functions and characteristics, enabling it to better perform during the motor winding and assembly process.

[0005] Further, the body as the main part of the winding framework provides a stable support foundation for coil winding. The V-shaped grooves in the circular array are designed ingeniously, with two V-shaped grooves provided between adjacent first protruding parts, and the groove bottom of the V-shaped groove is provided with a circular arc surface. This structure is conducive to the close fit of the coil to the groove wall during winding, and the uniform distribution of the coil in the groove, avoiding the accumulation and crossing of the coil in the groove. The circular arc surface of the groove bottom can reduce the wear of the coil during winding and operation, reduce the heat generated by friction, and improve the working efficiency and reliability of the motor. For example, in high-speed motors, the stability and heat dissipation of the coil on the winding framework are particularly important, and the V-shaped groove structure of the winding framework can effectively meet this demand.

[0006] Further, the first protruding part circumferential array is arranged on one side of the body and integrally formed with the body. Mirror image arc-shaped limiting parts are arranged at the openings of adjacent V-shaped grooves, which can further limit the edges of the coil during winding and prevent the coil from falling out of the groove. The first protruding part is arranged to be contracted outward along the axis for the first time, and the end thereof is integrally formed with a butt joint part arranged to be contracted outward along the axis for the second time, and the inclination of the first contraction is much smaller than that of the second contraction. The special shape and layout design of the fifteen first protruding parts have multiple effects. During winding, the first protruding part can separate and position the coil, so that coils of different turns can be wound in order in the corresponding V-shaped groove area, improving the neatness and accuracy of winding. During motor assembly, the shape of the first protruding part and the butt joint part can be closely matched with other parts of the motor (such as the motor end cover), to position and fix the winding skeleton, ensure the position of the winding skeleton in the motor is accurate and stable, and reduce the problem of motor performance degradation caused by displacement of the winding skeleton.

[0007] Further, the second protruding part includes a connecting arm extending radially towards the center of the body, and a positioning column extending outward is arranged on one side of the connecting arm, and the positioning column is arranged reversely to the first protruding part. Four connecting arms are circumferentially arranged on the body and integrally formed, and two diode through holes are arranged on the mirror image connecting arms. Two ear-shaped connecting arms are symmetrically arranged on the body and integrally formed. The connecting arm structure of the second protruding part provides additional strength and stability to the winding skeleton, so that it can withstand greater external force without deformation. The positioning column facilitates the positioning and cooperation of the winding skeleton with other parts during motor assembly, improving the accuracy and efficiency of assembly. The design of the diode through hole provides a convenient condition for integrating electronic components such as diodes on the winding skeleton. For some motors that require special circuit design (such as brushless motors), the diode can be directly installed on the winding skeleton, simplifying the circuit connection structure of the motor, reducing the length of the circuit and the number of connection points, reducing the risk of circuit failure, and saving the space inside the motor, which is conducive to the miniaturization design of the motor.

[0008] Compared with the prior art, the utility model has the advantages of:

[0009] 1) The V-shaped groove of the body circumferential array, the groove bottom arc surface is provided, which provides an ideal basic form for winding. In the winding process, the enameled wire can naturally adhere to the arc surface and uniformly distribute in the V-shaped groove, effectively avoiding the accumulation of turns or uneven local stress caused by unreasonable groove bottom shape. The arc-shaped limiting part mirror set at the opening of the adjacent V-shaped groove further enhances the constraint of the coil. When the winding machine drives the enameled wire to wind, the arc-shaped limiting part can prevent the coil from falling out of the slot, ensuring the neatness and stability of the coil during winding. When the high-speed motor is running, the stable winding structure can reduce electromagnetic interference and energy loss caused by coil shaking, improve the running efficiency and reliability of the motor.

[0010] 2) The fifteen first protruding parts are circumferentially arranged on one side of the body and integrally formed with the body. In the winding process, the first protruding part plays an accurate positioning and separation role for the coil. Two V-shaped grooves are provided between adjacent first protruding parts, so that different coil turns can be wound in the corresponding V-shaped groove area in an orderly manner, clearly dividing the winding area and improving the precision and regularity of winding. Moreover, the first protruding part is provided with a first contraction along the axis, and the butt joint part at the end is provided with a second contraction along the axis, and the inclination of the first contraction is much smaller than that of the second contraction. This special shape design plays a key role in the motor assembly process, can realize close cooperation with other motor parts (such as end cover, etc.), accurately position the winding skeleton in the motor, prevent the winding skeleton from shifting or rotating during motor operation, thereby ensuring the relative position stability between the winding and other motor parts, and ensuring the stable and reliable electrical performance of the motor.

[0011] 3) The connecting arm of the second protruding part is integrally formed and extends along the radial direction to the center of the body, providing additional structural strength for the winding skeleton. The four connecting arms are circumferentially arranged on the body, and the uniformly distributed connecting arms can effectively disperse external forces and enhance the overall rigidity of the winding skeleton, so that it is not easy to deform when subjected to external forces such as vibration and centrifugal force during motor operation. The positioning column vertically arranged on one side of the connecting arm is reversely arranged with the first protruding part. During motor assembly, the positioning column can accurately cooperate with the corresponding positioning structure on the other motor parts to realize quick and accurate positioning and installation, greatly improving the efficiency and precision of motor assembly and reducing the risk of performance degradation or failure of the motor due to assembly errors.

[0012] 4)The utility model discloses two mirror images setting connecting arm on be equipped with diode through -hole, this design provides the convenience for the expansion of motor function. For some motor (such as brushless motor etc.) that need special circuit design, can directly install diode on the winding framework. Through diode through -hole, diode can stably be installed on the connecting arm, not only simplify the circuit connection structure of motor, reduce the length of line and connecting point, reduce the probability of circuit failure, and save the space in the motor, be favorable to the miniaturization and light weight design of motor, make motor can keep compact structure layout while satisfying multiple function demand, improve the applicability and competitiveness of motor under different application scenarios.
