It can be connected to the stator core 3 through the non-lead end buckle point 105; the slot insulation buckle groove 11 and the integrated slot insulation 6 are buckled and fixed to each other, so that the lead end frame 1 and the non-lead end frame 2 are fixedly connected, and form a stator tooth with the stator core 3. After the winding is completed, the stator tooth forms a complete motor with the remaining stator teeth. The teeth are connected by the wiring method of the present invention to complete the manufacture of the motor stator.

The lead end frame and the non-lead end frame are spliced ​​in a single stator tooth of the modular motor to complete the winding, so that the insulating frame is suitable for the modular motor, and the frame buckle points corresponding to the lead end frame and the non-lead end frame are buckled and fixed with the original slots of the stator core, without the need to open additional holes or slots on the stator core, thereby avoiding the influence on the ferromagnetic properties of the motor.

[0047] In an optional embodiment of the present invention, a stator core buckle slot 21 is provided on the stator core 3, the lead terminal buckle point 5 is connected to one end of the stator core buckle slot 21, and the non-lead terminal buckle point 105 is connected to the other end of the stator core buckle slot 21.

[0048] The lead end frame 1 is fixed to the stator core 3 via the lead end buckle point 5 and the stator core buckle slot 21 , and the lead end frame 1 is fixed to the stator core 3 via the non-lead end buckle point 105 and the stator core buckle slot 21 .

[0049] In an optional embodiment of the present invention, the first winding portion 7 and the second winding portion 12 have the same winding structure, and the winding structure includes: a winding guide frame 13 and a winding guide tooth 14,

[0050] The winding guide frame 13, the winding guide teeth 14 and the lead end skeleton teeth 4 form a winding groove 22, or the winding guide frame 13, the winding guide teeth 14 and the non-lead end skeleton teeth 9 form a winding groove 22, and the winding groove 22 is used for winding.

[0051] In the embodiment of the present invention, the first winding portion 7 and the second winding portion 12 have the same winding structure, that is, the winding portions on the lead end skeleton 1 and the non-lead end skeleton 2 are the same. The winding structure includes a guide winding frame 13 and a guide winding tooth 14. The guide winding frame 13 and the guide winding tooth 14 are arranged at one end close to the lead end skeleton tooth 4, and the guide winding frame 13, the guide winding tooth 14 and the lead end skeleton tooth 4 form a winding groove 22. Correspondingly, the guide winding frame 13, the guide winding tooth 14 and the non-lead end skeleton tooth 9 enclose to form a winding groove 22. Winding is performed through the winding groove 22.

[0052] Furthermore, the integrated slot insulation 6 connects the winding guide frame 13 , the winding guide teeth 14 , and the lead end skeleton teeth 4 , and the integrated slot insulation 6 extends axially toward one side of the stator core 3 .

[0053] Furthermore, the wire passing portion 8 includes: a wire passing groove 15, a wire passing frame 16, a wire threading hole 17, a fixed wire socket 18, and a movable wire socket 19.

[0054] The wire groove 15 , the wire frame 16 , the wire threading hole 17 , the fixed wire socket 18 and the movable wire socket 19 are arranged on the winding guide frame 13 .

[0055] The lead end skeleton 1 is provided with a winding guide tooth 14, a winding guide frame 13, a wire slot 15, a wire rack 16, a fixed wire socket 18, a movable wire socket 19, a threading hole 17, and an integrated slot insulator 6. The winding guide tooth 14 and the winding guide frame 13 are vertically arranged on the lead end skeleton 1, and together with the lead end skeleton 1, they form a winding slot 22, and the two structures play a role in limiting the winding position of the enameled wire. The buckle point of the lead end skeleton 1 is located on the side of the skeleton teeth close to the iron core, and cooperates with the buckle slot 21 of the stator core to fix the skeleton. The wire slot 15, the wire rack 16, the threading hole 17, the fixed wire socket 18, and the movable wire socket 19 are arranged on the winding guide frame 13 to play a role in fixing the wire. The integrated slot insulator 6 connects the winding guide tooth 14, the skeleton teeth, and the main structure of the winding guide frame 13 in the radial direction, and extends axially to the side of the iron core, so that the enameled wire and the stator core 3 are effectively insulated.

[0056] In one example of the present invention, the tooth height of the guide winding tooth 14 is not less than 8 mm, and the difference between the tooth height of the guide winding tooth 14 and the height of the guide winding frame 13 is 11 mm; the thickness of the guide winding frame 13 is not less than 3 mm and not more than 3.5 mm, the tooth thickness of the guide winding is not less than 3.5 mm and not more than 4 mm, the ratio of the height of the guide winding frame 13 to the thickness of the lead end skeleton tooth 4 is not less than 2.5 and not more than 2.8, and the ratio of the tooth height of the guide winding tooth 14 to the thickness of the lead end skeleton tooth 4 is not less than 1.13 and not more than 1.15.

[0057] You can refer to Figure 2Taking the lead end skeleton 1 as an example, the winding groove 22 set on the lead end skeleton 1 is composed of skeleton teeth, a guide winding frame 13, and a guide winding tooth 14; the thickness of the skeleton tooth is h3, and the length is d5; the height of the guide winding frame 13 is h4, and the width is d2; the tooth height of the guide winding tooth 14 is h5, and the tooth width is d4; the groove width corresponding to the winding groove 22 formed by the winding frame, the guide winding tooth 14 and the lead end skeleton tooth 4 is d3.

[0058] To ensure that the winding frame 13 and the winding teeth 14 are not broken and effectively guided during the winding process, the height of the winding teeth 14 is h5 ≥ 8 mm, and the difference between the tooth height of the winding teeth 14 and the height of the winding frame 13 is h4-h5 = 11 mm; the thickness of the winding frame 13 is 3 mm ≤ d2 ≤ 3.5 mm, the thickness of the winding teeth 14 is 3.5 mm ≤ d4 ≤ 4 mm, and the skeleton tooth thickness h3 is proportional to h4 and h5 2.5 ≤ h4 / h3 ≤ 2.8, 1.13 ≤ h5 / h3 ≤ 1.15; to ensure that the stator core 3 used in conjunction with the skeleton achieves the best winding effect, the skeleton tooth length satisfies d5 = 28 mm, the winding slot 22 width is d3 = 16.5 mm, and the end surface distance d1 between the winding frame 13 and the lead end buckle point 5 is 5 mm.

[0059] The size and position relationship of the winding guide frame 13, winding guide teeth 14, winding groove 22, non-lead terminal frame 2, and non-lead terminal buckle point 105 provided on the non-lead terminal frame 2 are the same as those of the lead terminal frame 1, and all satisfy the above relationship.

[0060] In one example of the present invention, the contact length between the lead terminal buckle point 5 and the stator core 3 is not less than 0.6 mm and not more than 0.7 mm, and the width of the lead terminal buckle point 5 is not less than 3.58 mm and not more than 3.60 mm; the contact length between the non-lead terminal buckle point 105 and the stator core 3 is not less than 0.6 mm and not more than 0.7 mm, and the width of the non-lead terminal buckle point 105 is not less than 3.58 mm and not more than 3.60 mm.

[0061] You can refer to Figure 2 , taking the lead end skeleton 1 as an example, the contact length between the lead end buckle point 5 and the stator core 3 is h2. In order to ensure that the buckle point of the skeleton is buckled and fastened with the stator core 3, the contact length h2 between the lead end buckle point 5 and the stator core 3 is not less than 0.6mm and not more than 0.7mm, and the width of the lead end buckle point 5 is not less than 3.58mm and not more than 3.60mm. The corresponding non-lead end skeleton 2 has the same size, that is, the contact length between the non-lead end buckle point 105 and the stator core 3 is not less than 0.6mm and not more than 0.7mm, and the width of the non-lead end buckle point 105 is not less than 3.58mm and not more than 3.60mm. And you can refer to Figure 3, the lower end surface of the buckle point contacts the buckle slot 21 of the stator core, and the distance between the lower end surface of the buckle point (the side that contacts the core) and the framework winding frame 13 is a1. In order to make the framework buckle point fit the buckle slot 21 of the stator core, a fillet R1 is set. The width f1 of the framework buckle point and the size of the fillet R1 are in the same matching relationship as the stator core 3, 3.58mm≤d6≤3.60mm, and the radius of the fillet R1 is 1.15; the buckle point size of the lead end framework 1 is the same as the buckle point size of the non-lead end framework 2, and their size and position relationship all meet the above relationship.

[0062] Furthermore, the integrated slot insulation 6 is symmetrically arranged along the center line of the lead end skeleton 1, and the integrated slot insulation 6 and the lead end skeleton teeth 4 are injection molded simultaneously, perpendicular to the lead end skeleton teeth 4; the upper end surface of the integrated slot insulation 6 is connected to the lead end skeleton teeth 4, and the lower end surface of the integrated slot insulation 6 is connected to the slot insulation buckle groove 11.

[0063] You can refer to Figure 4 and Figure 5 The integrated slot insulation 6 is symmetrically arranged along the center line of the insulation skeleton. The integrated slot insulation 6 is simultaneously injection molded with the skeleton body and is perpendicular to the skeleton body. The upper end face of the slot insulation is connected to the lead end insulation skeleton body. The distance between the slot insulation contacting the enameled wire and the center line of the skeleton is i2, i2 = 8mm, so that the integrated slot insulation 6 fits the skeleton. In the transition section between the guide winding frame 13 and the skeleton teeth, and between the skeleton teeth and the guide winding teeth 14, fillets R2 and R3 are set, and the two fillet radii R2 = 3.5mm, R3 = 2mm; when assembled, the lower end face is buckled in the non-lead end skeleton 2 slot insulation buckle groove 11, the integrated slot insulation 6 has a thickness of i1 and a length of H. The length H can be changed according to the stator core 3 stacking height in the motor scheme. The length H = stator core 3 stacking height + 2mm, and the insulation thickness i1 satisfies 0.3mm≤i1≤0.35mm. In order to ensure that the integrated slot insulation 6 fits the core slot shape after assembly and improves the insulation capacity to suppress creepage, a slot insulation folding edge 20 is set at the position of the motor slot, and a fillet R4 is set at the joint of the two adjacent frames, and the radius of R4 = 3.5mm; the angle between the slot insulation folding edge 20 and the center line of the frame is α, α = 60°; during assembly, the lead end slot insulation is buckled into the non-lead end frame 2 slot insulation buckle groove 11 by 2mm, that is, the non-lead end frame 2 slot insulation buckle groove 11, the groove depth = 2mm; the groove width is d7, d7 and the slot insulation thickness i1 need to be highly matched to meet d7 = i1 + 0.08mm. At the same time, in order to facilitate the use of the needle winding machine, the needle passes through the slot insulation, and a chamfer with a length and width of 2mm is set on the slot insulation folding edge 20.

[0064] In an example of the present invention, the width of the guide frame 13 is not less than 48.4 mm ≤ and not greater than 48.43 mm ≤.

[0065] You can refer to Figure 6Taking the lead end skeleton 1 as an example, the width of the guide winding frame 13 is D (i.e., the widest part of the skeleton body), 48.4mm≤D≤48.43mm; to facilitate the overall assembly of the stator, a skeleton splicing seam is reserved on the guide winding frame 13, and its angle range is α1. The skeleton splicing seams on both sides are symmetrical about the center line of the skeleton, and there is a relationship of α1=2α2=40°; the distance from the guide winding frame 13 to the skeleton tooth bottom is a2, which satisfies 20mm≤a2≤20.03mm; to ensure the fit between the skeleton and the stator core 3 tooth pole shoe, the angle between the guide winding tooth 14 fitting the core pole shoe and the skeleton tooth is α3, and the angle between the guide winding tooth 14 and the skeleton tooth bottom is α4; α3=124.5°α4=171.2°, in order to make the guide winding tooth 14 guide the enameled wire well, the shape of the side of the winding tooth contacting the enameled wire is an arc with a radius of R8, and the radius of R8=48mm. Its center position is consistent with the center position of the stator core 3 matched with the skeleton. The above structure corresponding to the non-lead end frame 2 is the same as that of the lead end frame 1 and will not be described in detail here.

[0066] In an optional embodiment of the present invention, Figure 7 As shown, the threading hole 17, the wire groove 15, the wire rack 16, the fixed wire socket 18, and the movable wire socket 19 are all symmetrically arranged with respect to the center line of the frame. Figure 6 and Figure 7 As shown, the distance between the fixed line socket 18 and the movable line socket 19 and the center line is c3, the external length of the socket is d9, the width is a3 and the height is h6, and the internal reserved terminal interface size is: length d8, width a4, height h6, and there is a relationship: h6 = 4mm, d9-d8 = a3-a4 = 2mm.

[0067] like Figure 7 As shown, the distance between the wire groove 15 and the center line of the frame is c2, the groove width of the wire groove 15 is c1, the groove depth is h8, and the distance between the notch of the wire groove 15 and the socket is a5. The distance between the threading hole 17 and the center line of the frame is c4, the hole height is h7, and the hole width is c5; the distance between the bottom of the threading hole 17 and the socket is a6. Among them, the distances c2 and c4 are designed according to the maximum outer diameter of the average motor coil used in the implementation of the present invention, c2=c4=15mm; the width of the wire groove 15 and the width of the threading hole 17 c1=c5=4mm; the depth of the wire groove 15 h8, the height of the threading hole 17 h7 and the distance between the two components and the socket are related: a5-h8=0.8mm, a6-h7=2mm.

[0068] In an optional embodiment of the present invention, there are multiple wire passing frames 16 , which are distributed in a stepped manner along the winding guide frame 13 .

[0069] Reference Figure 8a and Figure 8bIn order to effectively separate and fix the wires, the wire racks 16 are distributed in a stepped manner along the guide winding frame 13, and there are 3 of them; the wire racks 16 have the same size, 2mm in length, 1.5mm in width, and 2mm in height; the top of the highest level wire rack 16 is 8mm away from the socket, and the second level wire rack 16 is centered on the center line of the skeleton, the distance between the wire racks 16 on both sides and the center line is 11mm, and the height difference between the wire racks 16 is 1.5mm.

[0070] The split skeleton in the embodiment of the present invention can be spliced ​​to a single stator tooth of the block motor to complete the winding. The skeleton buckle point is buckled and fixed with the original slot of the stator core 3. There is no need to open additional holes and slots on the stator core 3, which avoids the influence on the ferromagnetic properties of the motor. The slot insulation is injection molded together with the skeleton, and has good insulation performance; when the skeleton is buckled to the core, the slot insulation is also installed in place, eliminating the process of slot paper, which is more conducive to automated production; the special structure of the integrated slot insulation 6 is compatible with commonly used winding machine structures such as: needle type, flying fork type and special winding machine structures such as: core rotation type, straight row type, with high compatibility and strong adaptability. A wiring socket is set on the outer edge of the skeleton. After the winding of a single stator tooth is completed, the initial winding head and the final winding tail pass through the reserved 17 threading holes, and are fixed with special piercing terminals and plugged into the sockets, which play the role of fixing the wire heads and tails, etc., which is convenient for storage and external equipment to inspect the insulation of the wire package; after the stator is assembled, a special lead with a plug is used to complete the motor wiring and connect the three-phase winding. This design simplifies the motor wiring process and processing operations. In the application scenario of centralized flat wire winding, flat wire is not like conventional round wire, which is convenient for passing the wire, twisting, and wiring; when the block-type insulating skeleton described in the present invention uses flat wire, the winding wire heads and tails are fixed in the socket with terminals, and the passing and wiring are completed with finished wire harnesses, without considering that the flat wire is prone to insulation damage and hidden cracks when twisted. Through the use of special piercing terminals, sockets, and special finished lead wires, the motor tends to be modularized, and can be directly plugged in when wiring, which improves the efficiency of the motor wiring process to a certain extent and is more conducive to the realization of automated production. Through the design of the wire duct 15, the star point connection and the lead (external power supply) connection are separated in the "Y" type connection (parallel connection), such as Fig. 9 As shown, the two parts of the wiring are routed from the inner and outer edges of the frame respectively, the wiring is neat and beautiful, and easy to operate; at the same time, when using a needle winding machine, the wire groove 15 can be used to withdraw the needle after winding is completed. Through the wire rack 16, the motor U phase, V phase, and W phase wires are separated from each other to improve the insulation performance. When the insulation of a phase wire is damaged, sparks caused by the wire distance being too close can be avoided, resulting in motor failure and burning. Fig.10As shown, in the "triangle" (series) connection method, the wire rack 16 is used to separate the same-phase winding wires, and the external power lead is separated by the wire groove 15 and routed from the inner edge of the skeleton; the overall purpose of fixing the enameled wire and layering the wires of each phase is achieved by utilizing the wire holes 17, wire rack 16, wire groove 15 and socket structures on the skeleton. At the same time, a special terminal structure is adopted in conjunction with the skeleton socket, and the finished wire harness can be directly plugged in to connect each phase, eliminating the need for manual paint stripping and wire twisting and tinning. Compared with conventional motor wiring technology, it is convenient and beautiful, and the connection method is flexible and changeable, which is conducive to the mass production of block-type motors.
