Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically a brushless motor with no waste wire ends. Background Technology

[0002] In the manufacturing process of brushless motors, stator winding is one of the key steps. Traditional winding processes, especially for brushless stators with pin insertion, spot welding terminals, or pierced terminals, have many drawbacks. First, at the beginning and end of the winding process, it is necessary to leave and process the enameled wire ends, which usually produces long waste wire ends, wasting enameled wire material and increasing the cost of subsequent trimming and processing. Second, operations such as connecting the common terminal, winding the pins, and hanging wires on the terminals heavily rely on manual labor or semi-automated equipment, resulting in low production efficiency and poor consistency. In addition, the length control of the wire ends at the beginning is not precise, and the quality of twisting at the common terminal is unstable. These directly affect the performance reliability and manufacturing yield of the motor. To solve this problem, the inventors have proposed a brushless motor with no waste wire ends.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-3 As shown, this utility model discloses a brushless motor with no waste wire ends, including a support assembly, a stator module, and a winding module. The stator module is located on the inner side wall of the support assembly, and the winding module is located on the inner side wall of the stator module to facilitate coil winding. The winding module includes PIN posts 301 and terminal winding posts 310. Multiple PIN posts 301 are located on the upper surface of the support assembly and are spaced apart. The terminal winding posts 310 are located at one end of the support assembly. The motor also includes an inner winding wall 33 and an outer winding wall 34. The inner winding wall 33 is located on the inner side wall of the stator module, and multiple outer winding walls 34 are radially arranged and evenly distributed along the circumferential direction at one end of the stator module. The motor also includes a vertical plate 31 and a baffle 32. Multiple vertical plates 31 are located on one side of the stator module and are spaced apart. The baffles 32 are located between the outer winding walls 34 and the vertical plates 31. It also includes a receiving groove 35, which is opened at one end of the vertical plate 31 to facilitate the winding of the coil.

[0018] Specifically, the PIN post 301 array and the terminal winding post 310 directly undertake the functions of wire fixing and terminal connection in the winding end stage. Through the precise motion control of the winding module, the hanging and winding operations of the enameled wire on the terminal are ensured without additional manual intervention, realizing automated and precise connection.

[0019] Through the coordinated guidance of the inner / outer winding walls 34, the dynamic limiting of the vertical plate 31 and the baffle 32, and the temporary storage function of the receiving groove 35, the entire winding process eliminates the need to reserve the waste wire ends required in traditional processes. The entire process of wire fixing from the start to the end connection is completed within the preset path. The wire end length is precisely controlled by the component spacing, and the final wire end directly forms a reliable connection with the terminal winding post 310 or PIN post 301, completely eliminating the generation of waste wire ends. Through the wire management structure without waste wire ends (not shown) and the precise wire guiding design, there is no need to reserve long wire ends at the beginning and end stages of winding. The wire end is directly stored in the receiving groove 35, avoiding material waste and labor costs caused by cutting waste wire.

[0020] The stator module includes a stator core 21, which is located on the inner wall of the support assembly. One end of the stator core 21 has several radially spaced panels 23 evenly distributed along the circumference. Inner winding walls 33 are located on the inner wall of the stator core 21, and several radially spaced outer winding walls 34 are located at one end of the panels 23. A vertical plate 31 is located on one side of the panels 23. The inner wall of the panels 23 has multiple grounding holes 22 spaced apart. When the stator winding insulation is damaged (e.g., a single-phase ground fault), the grounding holes 22 provide a low-impedance path, allowing the fault current to flow into the ground through the grounding wire, triggering a circuit breaker or protective relay to trip quickly, preventing electric shock to personnel and equipment burnout.

[0021] Specifically, the stator module is centered on the stator core 21, with an inner winding wall 33 on its inner side wall and a yoke 101 on its outer side to enhance structural stability. A radially distributed array of panels 23 at one end of the stator core 21, together with the outer winding wall 34 array, forms a multi-dimensional winding space. During winding, the winding module uses the alternating guidance of the inner and outer winding walls 33 and 34 to achieve continuous winding of the enameled wire inside and outside the stator core 21 and at the end of the panels 23. The lateral receiving groove 35 on the vertical plate 31 serves as a temporary wire storage structure during winding, and, together with the baffle 32, provides lateral constraint on the wire, ensuring accurate and unbiased winding trajectory.

[0022] The support assembly includes a cylindrical body 11 and connecting arms 12. The connecting arms 12 are respectively disposed between the inner winding wall 33 and the cylindrical body 11. The PIN post 301 is located on the upper surface of the connecting arm 12, and the terminal winding post 310 is located at one end of the connecting arm 12. It also includes a yoke 101, which is disposed on the outer side wall of the stator core 21, and the stator core 21 is located on the inner side wall of the yoke 101.

[0023] Specifically, the cylindrical body 11 of the supporting component serves as the basic frame. The array of PIN posts 301 (multiple spaced) is fixed to the upper surface of the body via connecting arms 12, while the terminal winding posts 310 are located at the ends of the connecting arms 12. At the start of winding, the end of the enameled wire is directly fixed to a specific PIN post 301 or terminal winding post 310. Through the coordinated limiting of the vertical plate 31 (multiple spaced) and the baffle 32, the initial length of the wire end is precisely controlled within the process requirements, avoiding material waste caused by reserving excessively long wire ends in traditional processes.

[0024] By optimizing the winding module design, there is no need to leave long wire ends at the beginning and end of the winding process. Specifically, the precise winding and fixing of the coil is achieved through the coordinated operation of the PIN post 301, the terminal winding post 310, and the inner / outer winding wall 34. This avoids the problem of long waste wire ends caused by wire end processing in traditional processes, significantly reduces the waste of enameled wire material, and also reduces the labor and equipment costs of subsequent waste wire trimming.
