The positioning member 1 can be arranged in a "T" shape or an "I" shape; the positioning member 1 can be made of silicon steel, and the positioning member 1 can be formed by stacking a plurality of silicon steel sheets or integrally formed in a mold by silicon steel material. One end of the first connecting portion 11 can be connected to the middle of the second connecting portion 12, and the other end of the first connecting portion 11 is connected to the middle of the third connecting portion 13. So that the first connecting portion 11 forms a first wire groove and a second wire groove with half of the second connecting portion 12 and half of the third connecting portion 13 respectively; the first wire groove and the second wire groove are arranged symmetrically with the first connecting portion 11 as the axis.

[0035] The winding member 2 is composed of multiple strands of winding wire in parallel, and when the winding member 2 is wound along the first connecting portion 11, it passes through and is fixed in the first wire groove and the second wire groove in sequence. The winding member 2 is formed by multiple strands of winding wire that are tightly twisted and wound together; or the winding member 2 is formed by multiple strands of winding wire that are wound in parallel. The winding member 2 is composed of 6 strands of winding wire in parallel. The winding member 2 can be arranged by winding multiple strands of winding wire in parallel. In an optional scheme, the winding member 2 twists and fixes the multiple strands of winding wire in parallel through torsion, so that the wire diameter changes from a single strand to 6 strands; the wire diameter size is greatly increased. Two connecting wire heads can be set at both ends of the winding member 2 and connected to the positive and negative poles of the power supply respectively through the two connecting wire heads for conduction.

[0036] The utility model combines multiple strands of winding wires to form a winding member 2, and when the winding member 2 is wound along the first connection portion 11, it passes through and is fixed in the first wire groove and the second wire groove in sequence. By winding multiple strands of winding wires at the same time, the wire diameter of the winding member 2 is greatly increased, thereby greatly increasing the current density and torque of the winding member 2; at the same time, since the wire diameter of the single strand of winding wire is relatively small, and the rigidity of the winding wire does not change after the multiple strands of winding wires are combined, the winding member 2 can be simply wound by a winding machine, which is convenient to produce and efficient.

[0037] Embodiment 2:

[0038] In some optional ways, see 3-4, a motor winding structure of this embodiment includes: a positioning member 1, which is provided with a first connecting portion 11, a second connecting portion 12, and a third connecting portion 13, wherein the two ends of the first connecting portion 11 are respectively connected to the second connecting portion 12 and the third connecting portion 13, and the first connecting portion 11, the second connecting portion 12, and the third connecting portion 13 are enclosed to form a first wire groove and a second wire groove; and a winding member 2, wherein the winding member 2 is composed of a plurality of winding wires in parallel, and when the winding member 2 is wound along the first connecting portion 11, it passes through and is fixed in the first wire groove and the second wire groove in sequence. The first clamping portion 14 and the second clamping portion 15 are respectively provided on both sides of the second connecting portion, and the first clamping portion 14 of one positioning member 1 is mutually meshed with the second clamping portion 15 of the adjacent positioning member 1. In this embodiment, the number of positioning members 1 can be multiple, and multiple positioning members 1 can be mutually clamped through the first clamping portion 14 and the second clamping portion 15. In this embodiment, the first clamping portion 14 can be a clamping groove, and the second clamping portion 15 can be a clamping protrusion, wherein the first clamping portion 14 and the second clamping portion 15 are arranged to engage with each other so that adjacent positioning members 1 can be connected and fixed through the first clamping portion 14 and the second clamping portion 15.

[0039] In some optional embodiments, the length of the second connection part is longer than the third connection part. By setting the second connection part longer than the third connection part, the positioning member 1 forms a larger opening in the first wire groove and the second wire groove, which is convenient for winding. At the same time, by using the second connection part 12 and the third connection part 13 of different lengths, when the positioning member 1 is spliced ​​into the positioning core ring 3, the third connection part 13 can be abutted or arranged adjacent to each other, avoiding the difficulty of forming a ring shape due to the different diameters of the inner and outer rings.

[0040] In some optional ways, a plurality of the positioning members 1 are connected end to end by the first clamping portion 14 and the second clamping portion 15 to form a positioning core ring 3, and in the positioning core ring 3, two adjacent third connecting portions 13 are arranged without contact. The positioning core ring 3 of the utility model is spliced ​​by a plurality of positioning members 1. When winding, the winding wire is first wound along the first connecting portion 11 of the positioning member 1; and then the plurality of positioning members 1 wound with the winding members 2 are spliced. The convenience of winding is greatly improved, and the slot fullness of the first wire slot and the second wire slot of the positioning member 1 is provided, so as to further improve the inductance efficiency and ensure the normal operation of the motor.

[0041] In some optional ways, the adjacent positioning members 1 are fastened and fixed by welding or gluing; in this embodiment, after the positioning member 1 is fixed, the positioning core ring 3 can be locked and fixed again by welding or gluing to improve the stability of the motor. The positioning member 1 is also provided with a connection kit, the connection sleeve is connected to the outer surface of the first connecting member, and the winding member 2 is wound and fixed on the connection sleeve. In this embodiment, the connection kit can be made of plastic or rubber material, which is used to strengthen the positioning of the winding member 2, so that the structure of the winding member 2 is more stable.

[0042] In some optional embodiments, the angle A between the first connection surface of the second connection portion 12 and the first connection portion 11 is a right angle, and the angle B between the second connection surface of the third connection portion 13 and the first connection portion 11 is an obtuse angle. The utility model sets the angle between the connection surface of the second connection portion 12 and the first connection portion 11 to a right angle, and the winding wire can be stably limited by the second connection portion 12. By setting the connection surface angle between the third connection portion 13 and the first connection portion 11 to an obtuse angle, the opening size of the first wire groove and the second wire groove is increased, which is more convenient for winding.

[0043] In some optional embodiments, the outer side surface of the second connection portion 12 is an arc-shaped surface, and a first groove 16 is provided in the middle of the outer side surface of the second connection portion 12. In this embodiment, the outer side surface of the second connection portion 12 is an arc-shaped surface, so that the second connection portion 12 can be a structure with a high middle and low ends, thereby increasing the strength of the second connection portion 12 and improving the stability of the second connection portion 12. In addition, the first groove 16 is provided in the middle of the outer side surface of the second connection portion 12 so that the first clamping portion 14 and the second clamping portion 15 located in the second connection portion 12 can generate elastic force by squeezing the second connection portion 12 body when clamping, thereby improving the convenience and efficiency of the installation of the positioning member 1 when installing.

[0044] In some optional embodiments, the winding member 2 is formed by twisting a plurality of winding wires together, see Figure 1 Or the winding member 2 is formed by winding multiple winding wires in parallel, see Figure 2. In the present embodiment, the winding member 2 can be formed by twisting and winding multiple strands of winding wires together, or it can be formed by winding in parallel. The wire diameter of the winding wire is increased by aligning multiple strands of winding wire. The winding member 2 is composed of 6 strands of winding wire in parallel. The utility model aligns multiple strands of winding wires to form the winding member 2, and when the winding member 2 is wound along the first connecting portion 11, it passes through and is fixed in the first wire groove and the second wire groove in sequence. By winding multiple strands of winding wire at the same time, the wire diameter of the winding member 2 is greatly increased, thereby greatly increasing the current density and torque of the winding member 2; at the same time, since the wire diameter of the single-strand winding wire is relatively small, and after the multiple strands of winding wire are aligned, the rigidity of the winding wire does not change, the winding member 2 can be simply wound by a winding machine, which is convenient to produce and efficient.
