Description

Technical Field

[0001] This utility model belongs to the technical field of motor winding structure, and particularly relates to a motor coil winding structure. Background Technology

[0002] The existing motor stator winding structure includes an annular stator yoke, which has a plurality of stator grooves. Each winding coil is wound in the stator groove in a continuous interval of forward, reverse, forward, and reverse directions, that is, wound in an odd number of grooves or a corner number of grooves to achieve internal fixation of the stator.

[0003] The existing motor stator winding structure lacks auxiliary limiting structure during winding, requiring manual handling of the fine enameled wire, which is difficult for small motor coils. As a result, uneven winding of the coils occurs, affecting the performance of the motor. Utility Model Content

[0004] The purpose of this utility model is to provide a motor coil winding structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A motor coil winding structure includes a stator inner ring. The side wall of the stator inner ring is provided with a plurality of slots arranged in a circumferential array. Each slot is provided with an insert plate, and each insert plate is provided with a winding plate on the side away from the stator inner ring. A truncated cone that can move along its length direction is sleeved on the winding plate. A winding groove is formed between the truncated cone and the insert plate, and a driving structure for driving the truncated cone to move is provided on the winding plate.

[0006] Preferably, the slot has an open top and closed bottom structure, and the size of the insert plate matches the size of the slot.

[0007] Preferably, the inner walls on both sides of the slot are provided with vertically distributed trapezoidal grooves, and the inner walls on both sides of the insert plate are provided with trapezoidal sides corresponding to the trapezoidal grooves. The size of the trapezoidal sides matches the size of the trapezoidal grooves, and the trapezoidal sides are slidably connected to the trapezoidal grooves.

[0008] Preferably, the dimensions of the insert plate and the truncated cone are both larger than the dimensions of the winding plate.

[0009] Preferably, the middle part of the surface of the cone is provided with a sliding opening whose size matches that of the winding plate, and the winding plate passes through the sliding opening and is slidably connected to it.

[0010] Preferably, the driving structure includes a lead screw, a rectangular opening is provided in the middle of the surface of the winding plate, the lead screw is rotatably connected to the rectangular opening through a bearing, a threaded block is provided in the middle of the sliding opening and threadedly connected to the lead screw, an internal hexagonal cap is provided at the end of the lead screw away from the insert plate, and a groove is provided in the middle of the end of the winding plate away from the insert plate, the internal hexagonal cap is located in the groove.

[0011] Preferably, the upper and lower ends of the winding plate are provided with wire-locking ports at the connection points with the insertion plate.

[0012] The motor coil winding structure of this utility model has the following advantages:

[0013] 1. This utility model, through the setting of the sliding mouth, allows the truncated cone to move along the length direction of the winding plate, so that the truncated cone moves closer to the insertion plate. During winding, the enameled wire is wound around the winding groove. After a certain number of turns, the truncated cone moves closer to the insertion plate, so that the truncated cone and the coil come into contact. At this time, the truncated cone applies an inward force to the coil, making the gaps between the coils smaller, and further making the coil winding more uniform, thereby reducing the difficulty of coil winding. At the same time, it makes the coil winding tighter. Due to the smaller gaps between the wires, the tightly wound coil has a smaller capacitance, which helps to improve the frequency response and stability of the circuit, thereby reducing capacitance, increasing inductance, and enhancing magnetic field strength.

[0014] 2. This utility model uses a tool to rotate the internal hexagonal cap, causing the lead screw to rotate. Under the action of the threaded block, the cone moves closer to the insertion plate, thereby squeezing the coil tightly. This effectively prevents the coil from becoming loose and the gaps from widening. Furthermore, the connection and drive via the lead screw and threaded block ensures that the cone remains stationary without external force, providing a long-term squeezing effect on the coil and thus improving product quality.

[0015] 3. By using trapezoidal sides and trapezoidal slots, when the insert plate is inserted into the slot, the trapezoidal sides will correspondingly engage with the trapezoidal slots, thereby limiting and fixing the insert plate. This effectively prevents the insert plate from detaching from the slot and ensures the stability of the structure.

[0016] 4. The wire clamping opening allows the end of the enameled wire to be secured in the clamping opening at the beginning of winding, thus facilitating winding and improving winding efficiency. Attached Figure Description

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a motor coil winding structure according to this utility model.

[0029] like Figure 1-4 As shown, the present invention discloses a motor coil winding structure, including a stator inner ring 1. The side wall of the stator inner ring 1 is provided with a plurality of slots 6 arranged in a circumferential array. Each slot 6 is provided with an insert plate 2. The slot 6 has a top-open and bottom-closed structure, and the size of the insert plate 2 matches the size of the slot 6. By setting the slot 6 to have a top-open and bottom-closed structure, the insert plate 2 can be positioned. When the insert plate 2 is inserted into the slot 6, the top and bottom of the insert plate 2 are flush with the top and bottom of the stator inner ring 1. Both sides of the slot 6 have vertically distributed trapezoidal grooves 7 on their inner walls. Both sides of the insert plate 2 have trapezoidal sides 8 that correspond to the trapezoidal grooves 7. The size of the trapezoidal sides 8 matches the size of the trapezoidal grooves 7, and the trapezoidal sides 8 and the trapezoidal grooves 7 are slidably connected. By setting the trapezoidal sides 8 and the trapezoidal grooves 7, when the insert plate 2 is inserted into the slot 6, the trapezoidal sides 8 will be correspondingly engaged in the trapezoidal grooves 7, thereby limiting and fixing the insert plate 2. This can effectively prevent the insert plate 2 from detaching from the slot 6 and ensure the stability of the structure.

[0030] Each insert plate 2 has a winding plate 3 on the side away from the inner stator ring 1. The upper and lower ends of the winding plate 3 are equipped with wire-clamping slots 9 at their connection points with the insert plate 2. These slots allow the end of the enameled wire to be secured during initial winding, facilitating the winding process and improving winding efficiency. A truncated cone 4, movable along its length, is fitted onto the winding plate 3. A winding groove 5 is formed between the truncated cone 4 and the insert plate 2. Both the insert plate 2 and the truncated cone 4 are larger than the winding plate 3, thus creating the winding groove 5 between them. The cone 4 has a sliding opening 10 at the center of its surface, which matches the size of the winding plate 3. The winding plate 3 passes through the sliding opening 10 and is slidably connected to it. The sliding opening 10 allows the cone 4 to move along the length of the winding plate 3, so that the cone 4 moves closer to the insertion plate 2. During winding, the enameled wire is wound onto the winding groove 5. After a certain number of turns, the cone 4 moves closer to the insertion plate 2, so that the cone 4 contacts the coil. At this time, the cone 4 applies an inward force to the coil, making the gaps between the coils smaller and making the coil winding more uniform, thereby reducing the difficulty of coil winding and making the coil winding tighter. Tightly wound coils have smaller gaps between the wires and smaller capacitance, which helps to improve the frequency response and stability of the circuit, thereby reducing capacitance, increasing inductance and enhancing magnetic field strength.

[0031] The winding plate 3 is equipped with a drive structure for moving the cone 4. The drive structure includes a lead screw 12. A rectangular opening 11 is provided in the middle of the surface of the winding plate 3. The lead screw 12 is rotatably connected to the rectangular opening 11 through a bearing. A threaded block 14 is provided in the middle of the sliding opening 10, which is threadedly connected to the lead screw 12. An internal hexagonal cap 13 is provided at the end of the lead screw 12 away from the insertion plate 2. A groove is provided in the middle of the end of the winding plate 3 away from the insertion plate 2, and the internal hexagonal cap 13 is located in the groove. By rotating the internal hexagonal cap 13 with a tool, the lead screw 12 rotates. Under the action of the threaded block 14, the cone 4 moves closer to the insertion plate 2, thereby squeezing the coil tightly. This can effectively prevent the coil from becoming loose and the gaps from widening. Moreover, the drive is connected by the lead screw 12 and the threaded block 14. Without the action of external force, the cone 4 is in a fixed and stationary state, which can exert a long-term squeezing effect on the coil, thereby improving product quality.
