For the multiphase motor, in the winding process, the ends of the windings can penetrate out of the skeleton yokes 112, the connecting wires 115 can play a role in connection, and the connecting wires 115 are used for connecting the ends of the windings penetrating out of the two skeleton yokes 112.
After the motor frame 100 is machined, at least two sub-frames 110 are sequentially distributed along the same straight line direction, and when the sub-frames 110 need to be connected with the stator punching block 210, at least two sub-frames 110 need to be distributed along the circumferential direction of the stator assembly 200, that is, two adjacent sub-frames 110 need to be rotated by a certain angle, so that the positions of the sub-frames 110 and the stator punching block 210 correspond.

Specifically, the distance between the outer periphery of the support portion 114 and the axis of the stator assembly 200 is H1, the distance between the outer periphery of the backbone yoke 112 and the axis of the stator assembly 200 is H2, and H1 is greater than H2, and compared to the outer periphery of the backbone yoke 112, the outer periphery Zhou Gengyuan of the support portion 114 is away from the axis of the stator assembly 200, so that when the connecting wire 115 passes through the support portion 114, the support portion 114 can jack up the connecting wire 115 in a direction away from the axis of the stator assembly 200. The length of the supporting portion 114 jack up the connecting wire 115 offsets the loose length of the connecting wire 115, so that the connecting wire 115 cannot loose, the connecting wire 115 can be stably wound on the skeleton yoke 112, the connecting wire 115 is not easy to separate from the skeleton yoke 112, and the reliability of the motor is guaranteed.
Note that the first positioning groove 113 protrudes from the outer peripheral surface of the backbone yoke 112, and the outer periphery of the backbone yoke 112 indicated in the present invention is not the outer periphery of the first positioning groove 113.
The winding and the connecting wire 115 on the teeth of the skeleton may be an integral wire or a split wire.
As shown in fig. 2 and 3, in one possible embodiment, the sub-skeleton 110 is taken along the radial direction of the stator assembly 200, the center line of the skeleton tooth portion 111 is set to be L1, the intersection point of the side, facing the axis of the stator assembly 200, of the skeleton yoke portion 112 and the center line L is set to be a, the intersection point of the center line L1 and the axis of the stator assembly 200 is set to be a dot, and the distance between the dot and the intersection point a is set to be a radius, so as to obtain a circle C; let the straight line passing through the intersection point a be a straight line L2, the straight line L2 is deflected in a direction approaching the support portion 114 with respect to the center line L1, and the angle θ between the straight line L2 and the center line satisfies: θ is 80-90 degrees; wherein the support 114 is located between the circle C and the straight line L2.
In this embodiment, in order to ensure that the supporting portion 114 can effectively jack up the connection wire 115, it is necessary to limit the setting range of the supporting portion 114.
Specifically, the sub-bobbin 110 is cut along the radial direction of the stator assembly 200, and a cross section of the sub-bobbin 110 is obtained, and the description of the bobbin yoke 112 in this embodiment is directed to a cross section of the bobbin yoke 112. The backbone yoke 112 has a center line, which may be a symmetry line of the backbone yoke 112, the center line of the backbone yoke 112 is L1, and one side of the backbone yoke 112 connected to the backbone tooth 111 has an intersection point, i.e., an intersection point a, with the center line L1. A circle C is obtained by rounding the intersection point of the center line L1 and the axis of the stator assembly 200 with the distance from the dot to the intersection point a as a radius, and a boundary of the above range is determined.
The straight line L2 passes through the intersection point a, the straight line L2 forms an angle θ with the center line L1, wherein the straight line L2 is deflected in a direction approaching the support portion 114 as compared to the center line L1, and the angle θ of the straight line L2 with the center line L1 is between 80 ° and 90 °, thereby defining another boundary of the above range.
The supporting portion 114 is located between the two boundaries, that is, the supporting portion 114 is located between the circle C and the straight line L2, if the supporting portion 114 is too biased toward the circle C, the distance between the supporting portion 114 and the axis of the stator assembly 200 is smaller, which results in that the distance between the outer periphery of the supporting portion 114 and the axis of the stator assembly 200 is smaller than the distance between the outer periphery of the frame yoke 112 and the axis of the stator assembly 200, and at this time, the supporting portion 114 cannot play a role in jacking the connecting wire 115, but also causes the connecting wire 115 to be further loosened. If the support 114 is too far from the straight line L2, the support 114 may be too far from the axis of the stator assembly 200, and it may happen that the support 114 protrudes from the outer circumference of the stator assembly 200, and at this time, the support 114 may interfere with the installation of the stator assembly 200 and the housing.
The support 114 is defined between the circle C and the straight line L2, and the support 114 can not only effectively jack up the connection line 115, but also avoid the support 114 protruding the outer periphery of the stator assembly 200, and avoid interference with the assembly of the stator assembly 200 and the housing.
In one possible embodiment, the support 114 is provided at the circumferential edge of the tooth yoke.
In one possible embodiment, let the tangent line of the intersection point a be B, the supporting portion 114 is located between the tangent line B and the straight line L2.
In this embodiment, the setting position of the support 114 is further defined. Specifically, the skeleton yoke 112 has an arc structure, and makes a tangent to the intersection point a to obtain a tangent line B, and the support 114 is located between the tangent line B and the straight line L2. The support 114 is located within this range, and interference of the support 114 with the assembly of the stator assembly 200 and the housing can be further avoided.
As shown in connection with fig. 2 and 3, in one possible embodiment, the stator assembly 200 includes a plurality of stator punching blocks 210, the plurality of stator punching blocks 210 are sequentially spliced along the circumferential direction of the stator assembly 200, the number of motor frames is at least two, and one sub-frame 110 is connected to one stator punching block 210; the sub-frame 110 and the stator assembly 200 are taken radially of the stator assembly 200, and the support 114 extends beyond a radially extending edge of the stator segment 210.
In this embodiment, the number of motor frames 100 is at least two, each motor frame 100 includes at least two sub-frames 110, and adjacent two sub-frames 110 of the at least two sub-frames 110 are connected, i.e., each motor frame 100 includes at least two sub-frames 110 connected in sequence. One sub-frame 110 is connected with one stator punching block 210, that is, the sub-frame 110 and the stator punching block 210 are in one-to-one correspondence. Since each motor frame 100 includes at least two sub-frames 110, when assembling the at least two sub-frames 110 with the stator punching blocks 210, the two sub-frames 110 will be instructed to align with the at least two stator punching blocks 210, and the assembling of the at least two sub-frames 110 is completed at one time. I.e., one motor frame 100 is installed, the assembly of at least two sub-frames 110 and at least two stator bars 210 is completed. Compared with the mode of repeatedly installing the framework and the stator punching blocks in the related art, the motor framework 100 is provided with at least two sequentially connected insulator frameworks 110, so that the assembly procedures in the assembly process of the stator assembly are reduced, the assembly difficulty is reduced, and the production efficiency of the stator assembly is improved.
The number of the motor frameworks 100 is at least two, and at least two motor frameworks 100 can be sequentially installed, and the motor frameworks 100 are at least two, so that the alignment of the sub-frameworks 110 and the stator punching blocks 210 can be facilitated, and the convenience in the assembly process is further improved.
Because each motor skeleton 100 includes at least two sub-skeletons 110, at least two sub-skeletons 110 can be produced at one time when the motor skeleton 100 is produced, the processing procedures are reduced, and the production efficiency of the motor is further improved.
The number of sub-bobbins 110 may be the same or different among the motor bobbins 100, and for example, when the number of stator bars 210 is 6, two motor bobbins 100 may be connected with 6 stator bars 210. The two motor bobbins 100 may include 3 sub-bobbins 110, respectively. It is also possible that one motor skeleton 100 includes 2 sub-skeletons 110 and another motor skeleton 100 includes 4 sub-skeletons 110.
The support 114 protrudes beyond an edge of the stator block 210 extending in the radial direction, so the support 114 is provided at one end of the backbone yoke 112. In the present invention, the support portion 114 is provided at the end of the yoke portion 112, which corresponds to lengthening the yoke portion 112, and the support portion 114 is provided at the end of the yoke portion 112, which improves the convenience of processing the support portion 114, as compared with the yoke portion of the related art. In addition, the manner of lengthening the frame yoke 112 has less structural modification to the frame yoke 112 than the frame yoke 112 in the related art, and can reduce the difficulty in machining the motor frame 100.
In one possible embodiment, the sub-skeleton 110 further comprises: the second positioning groove is formed in the supporting portion 114, and the connecting wire 115 passes through the second positioning groove.
In this embodiment, the supporting portion 114 is formed with a second positioning groove, and the connecting wire 115 can pass through the second positioning groove. The second positioning groove plays a limiting role on the connecting wire 115, and the connecting wire 115 is not easy to slide relative to the supporting portion 114, so that the supporting portion 114 can stably jack up the connecting wire 115, and the coil is tightly wound on the framework yoke portion 112.
As shown in connection with fig. 2 and 4, in one possible embodiment, the width of the first positioning groove 113 is W, and the maximum wire diameter of the connecting wire 115 is D, which satisfies the following requirements: w is greater than or equal to 1.4XD.
In this embodiment, the dimensional relationship of the width of the first positioning groove 113 and the wire diameter of the connecting wire 115 is defined. If the width of the first positioning groove 113 is smaller than the maximum wire diameter of the connecting wire 115, the connecting wire 115 is extruded and deformed by the first positioning groove 113, which is easy to damage the connecting wire 115. If the width of the first positioning groove 113 is substantially the same as the maximum wire diameter of the connecting wire 115, the connecting wire 115 needs to be aligned with the first positioning groove 113 to assemble the connecting wire 115 into the first positioning groove 113, and this assembly mode requires a high positioning requirement, resulting in a high assembly difficulty. Therefore, the width W of the first positioning groove 113 is more than or equal to 1.4 xD, the connecting wire 115 is easy to be assembled into the first positioning groove 113, and the convenience of the winding process can be improved.
As shown in connection with fig. 2 and 4, in one possible embodiment, skeletal yoke 112 includes: a connection portion 1121 and a wiring portion 1122, the connection portion 1121 being connected to the skeleton tooth portion 111; the wire portion 1122 is connected to the connecting portion 1121, the connecting portion 1121 is located between the wire portion 1122 and the skeleton tooth portion 111, and the first positioning groove 113 is provided in the wire portion 1122.
In this embodiment, the connection portion 1121 and the routing portion 1122 extend along the axial direction of the stator assembly 200, the routing portion 1122 is provided with the first positioning groove 113, and the connection portion 1121 spaces the routing portion 1122 and the skeleton tooth portion 111 such that the first positioning groove 113 and the skeleton tooth portion 111 maintain a certain spacing. In the winding process, the wires in the first positioning groove 113 and the wires on the skeleton tooth part 111 are not easy to mix, so that the convenience of the winding process is improved.
As shown in connection with fig. 2 and 4, in one possible embodiment, the thickness of the connection portion 1121 is L3, and the thickness of the routing portion 1122 is L4, which satisfies the following requirements: l4 is more than or equal to 0.8XL3.
In this embodiment, the relative relationship between the thickness of the connection portion 1121 and the thickness of the routing portion 1122 is defined, and since the first positioning groove 113 is provided on the routing portion 1122, the thickness of the routing portion 1122 can be appropriately reduced, and the insulation hanger is prevented from being thicker at the routing portion 1122 and reducing the mounting process. In addition, since the connection portion 1121 serves to connect the wiring portion 1122 and the frame tooth portion 111, it is necessary to secure the thickness of the connection portion 1121 and to secure the structural stability of the motor frame 100.
