Description

Conductive connector, stator assembly and motor Technical Field

[0001] The embodiments of the present application relate to the field of electromechanics, and in particular to a conductive connection seat, a stator assembly, and a motor. Background Art

[0002] The motor stator's conductive connectors electrically connect the motor's multiple windings, arranged in a circular array. External current is transmitted through the stator's conductive connectors to each winding. The current flowing through each winding generates magnetic force, driving the motor's rotor relative to the stator. To meet performance and miniaturization requirements, existing motors have small spacing between stator windings. This can easily lead to contact between damaged paint surfaces on adjacent windings, resulting in a short circuit and low safety. Technical issues

[0003] The present application provides a conductive connection seat, a stator assembly and a motor, which can improve the safety performance of the motor. Technical Solutions

[0004] To solve the above technical problems, the present application provides, in a first aspect, a conductive connection socket for a motor stator. The motor stator includes a plurality of windings, each winding including a first end and a second end. The conductive connection socket includes:

[0005] a first main input terminal;

[0006] a first electrical connection portion electrically connected to the first main input terminal, the first electrical connection portion being configured to connect to a first end of a portion of a winding of a motor stator;

[0007] The conductive connection base is configured to connect the windings connected to the first electrical connection portion in parallel.

[0008] A second aspect of the present application further provides a conductive connection base for a motor stator, which is used to connect to the winding of the motor. The conductive connection base includes a plurality of conductive connection units, and the conductive connection units include:

[0009] Main input terminals and electrical connections,

[0010] The electrical connection portion includes a first branch and a second branch,

[0011] The first branch is arranged around the first height of the motor axis.

[0012] The second branch is disposed around a second height of the motor axis.

[0013] A third aspect of the present application further provides a stator assembly for a motor, comprising:

[0014] stator core;

[0015] a plurality of windings wound on the stator core, each winding including a first end and a second end; and

[0017] A fourth aspect of the present application further provides a motor, comprising:

[0018] The stator assembly described above; and

[0019] A rotor assembly is rotatable relative to a stator assembly. Beneficial effects

[0020] The conductive connector provided in the embodiments of the present application can reduce the current flowing through the windings of the motor stator (in the prior art, the windings connected by the first electrical connection portion are connected in series, and to ensure the same winding voltage, the current is relatively large). Therefore, the diameter of the wire wound into the winding can be smaller, making the volume of a single winding smaller and the spacing between adjacent windings larger. This solution, on the one hand, reduces the probability of adjacent windings contacting and short-circuiting, thereby improving the safety performance of the motor. On the other hand, it also increases the possibility of removing the insulating paper arranged between adjacent windings, thereby reducing the material cost and processing cost of the motor.

[0037] In order to facilitate understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0039] The motor stator's conductive connector electrically connects the stator's ring-shaped windings. External current is transmitted through the connector to the windings, generating magnetic forces that drive the motor's rotor relative to the stator. The connector includes three main input terminals, which transmit currents of three different phases to the corresponding windings.

[0040] The applicant also found that in the existing motor stator, in order to meet the user's high performance and miniaturization requirements, the spacing between each winding is small. In order to reduce the probability of short circuit between two adjacent windings, insulating paper needs to be set between each winding, which is costly.

[0041] In view of this, referring to Figures 1-12, an embodiment of the present application provides a conductive connection seat 100 for a motor 10. When the motor 10 uses the conductive connection seat 100 in this embodiment to connect each winding 200, the volume of the winding can be optimized to improve the safety performance of the motor 10.

[0042] The conductive connector 100 is used to electrically connect to the windings 200 of the motor stator. The number of windings 200 in the motor 10 can be determined based on specific needs. For ease of description, the following embodiments illustrate a motor 10 having twelve windings 200 arranged around a first axis 400. Specifically, each winding 200 has two ends for connecting to the conductive connector 100, hereinafter referred to as a first end 210 and a second end 220. The twelve windings 200 have a total of twelve first ends 210 and twelve second ends 220. The placement of the first end 210 and second end 220 of each winding 200 depends on specific needs. In this embodiment, the first end 210 of each winding 200 is located on an outer circle relatively far from the first axis 400, and the second end 220 of each winding 200 is located on an inner circle relatively close to the first axis 400.

[0043] In this embodiment, the conductive connection seat 100 includes three conductive connection units, each of which includes a main input terminal and an electrical connection part. For the sake of distinction, the following description will be given by taking the first conductive connection unit including the first main input terminal 110 and the first electrical connection part 140, the second conductive connection unit including the second main input terminal 120 and the second electrical connection part 150, and the third conductive connection unit including the third main input terminal 130 and the third electrical connection part 160 as an example. The first main input terminal 110, the second main input terminal 120 and the third main input terminal 130 are used to obtain three-phase current. It can be understood that in other embodiments, the number of main input terminals and electrical connection parts can be set according to the situation. For example, in a two-phase motor, only two main input terminals and two electrical connection parts need to be provided. This article will take a three-phase motor as an example to explain the features of the present invention in detail.

[0044] The first main input terminal 110 is electrically connected to a first electrical connection portion 140, which is configured to electrically connect to the first ends 210 of the windings 200 of the motor 10. Specifically, in this embodiment, the first electrical connection portion 140 is configured to connect to the first ends 210 of four different windings 200 at the same potential, thereby enabling the first electrical connection portion 140 to transfer electrical energy to the four windings 200. Specifically, in this embodiment, the first electrical connection portion 140 is directly connected to the four windings 200.

[0045] In other embodiments, the first electrical connection portion 140 may also be directly connected to five, six or more windings 200 , which will not be elaborated here.

[0046] 1 and 5 , in this embodiment, the conductive connector 100 is configured to connect the windings 200 connected to it at the same potential in parallel. Specifically, the first end 210 of each winding 200 is electrically connected to the first electrical connection portion 140 , and the second end 220 of each winding 200 is electrically connected to a single point (specifically, the fourth electrical connection portion 170 , described below).

[0047] In this embodiment, compared to a structure in which the winding 200 directly connected to the first electrical connection portion 140 is first connected in series with another winding 200 (a winding 200 not directly connected to the first electrical connection portion 140) and then connected in parallel, to ensure that each winding 200 receives the same voltage, the current flowing through the winding 200 in this application can be reduced (in the prior art, the windings 200 connected to the first electrical connection portion 140 are connected in series, resulting in a relatively higher current). Therefore, the diameter of the wire wound into the winding 200 can be smaller, making the volume of a single winding 200 smaller and the spacing between adjacent windings 200 larger. This solution, on the one hand, reduces the probability of adjacent windings 200 contacting and thus short-circuiting, thereby improving the safety performance of the motor 10. On the other hand, it also increases the possibility of removing the insulating paper arranged between adjacent windings 200, thereby reducing the material cost and processing cost of the motor 10.

[0048] The second main input terminal 120 is electrically connected to the second electrical connection portion 150. The second electrical connection portion 150 is used to directly connect to the first ends 210 of at least four windings 200. In this embodiment, the second electrical connection portion 150 is directly connected to the first ends 210 of the four windings 200. The second main input terminal 120 transfers the current it receives to the second electrical connection portion 150, and the second electrical connection portion 150 transfers the current to the four windings 200 connected thereto.

[0049] The third main input terminal 130 is electrically connected to the third electrical connection portion 160. The third electrical connection portion 160 is configured to directly connect to at least the first ends 210 of the four windings 200. In this embodiment, the third electrical connection portion 160 is directly connected to the first ends 210 of the four windings 200. The third main input terminal 130 transfers the current it receives to the third electrical connection portion 160, which in turn transfers the current to the four connected windings 200.

[0050] In this embodiment, the conductive connector 100 further includes a fourth electrical connection portion 170, which is electrically connected to the second ends 220 of all windings 200. Specifically, the second end 220 of each winding 200 is electrically connected to the fourth electrical connection portion 170, and the first ends 210 of all windings 200 are electrically connected to one of the first main input terminal 110, the second main input terminal 120, or the third main input terminal 130. Consequently, all windings 200 of the motor stator are connected in a star configuration.

[0051] In this embodiment, the conductive connection socket 100 can connect the windings 200 connected to each main input terminal in parallel, and the windings 200 of the stator of the motor 10 can be connected in a star shape, thereby further reducing the current flowing between the windings 200, so that each winding 200 can use a wire with a smaller diameter, reducing the probability of contact short circuit between adjacent windings 200, thereby improving the safety performance of the motor 10.

[0052] In this embodiment, the first, second, and third main input terminals 110, 120, and 130 are all arranged along a first direction X (specifically, the axial direction of the motor 10). The first, second, and third main input terminals 110, 120, and 130 are arranged in a circular array centered around the first axis 400 (specifically, the rotational axis of the motor 10), with the array angle being 360 degrees. In other words, along the first circumferential direction M, the first, second, and third main input terminals 110, 120, and 130 are each spaced 120 degrees apart with respect to the first axis 400. This structural arrangement can reduce the maximum circumferential dimensions of the first electrical connection part 140, the second electrical connection part 150 and the third electrical connection part 160, so that the first electrical connection part 140, the second electrical connection part 150 and the third electrical connection part 160 can have less processing waste during processing, thereby reducing the processing costs of the first electrical connection part 140, the second electrical connection part 150 and the third electrical connection part 160.

[0053] It is understandable that in other embodiments, the first main input terminal 110 , the second main input terminal 120 , and the third main input terminal 130 may also be designed to have other arrangement angles according to actual needs, which will not be elaborated here.

[0054] Specifically, in this embodiment, referring to Figures 3-6 , the first electrical connection portion 140 includes a first branch 141 and a second branch 142 , each electrically connected to one end of the first main input terminal 110 . The first branch 141 is used to directly connect the first ends 210 of two windings 200 , while the second branch 142 is used to directly connect the first ends 210 of two additional windings 200 . In this solution, using two separate components, the first branch 141 and the second branch 142 , to connect the four windings 200 , respectively, reduces the overall size of the components of the first electrical connection portion 140 . Compared to a structure that uses a single component to simultaneously connect all four windings 200 , the first electrical connection portion 140 is less difficult to manufacture, produces less waste, and is less expensive. In other embodiments, the first branch 141 can connect the first ends 210 of three or more windings 200 , and the second branch 142 can also connect the first ends 210 of three or more windings 200 .

[0055] In this embodiment, the first main input terminal 110 extends along a first direction X (i.e., the motor axial direction), the first branch 141 extends along a first circumferential direction M about a first axis 400, and the second branch 142 extends along a second circumferential direction N about the first axis 400. The first circumferential direction M is opposite to the second circumferential direction N. The first axis 400 is parallel to the first direction X and is spaced apart from the first main input terminal 110. The first axis 400 may specifically be the rotational axis of the motor 10. Because the first branch 141 and the second branch 142 extend in different circumferential directions, they can more easily connect to the windings 200 at corresponding locations. This improves the overall structure of the first electrical connection portion 140 and reduces assembly complexity.

[0056] In this embodiment, referring to Figures 2, 5, and 6, the first branch 141 is disposed at a first height in the axial direction of the motor 10, and the second branch 142 is disposed at a second height in the axial direction of the motor 10. The first branch 141 and the second branch 142 are disposed at different positions in the axial direction of the motor 10 and are not located in the same plane.

[0057] 5-7 , in this embodiment, the first main input terminal 110 includes a first portion 111, a second portion 112, and a third portion 113. The first portion 111 extends along a first direction X, the second portion 112 extends along a first circumferential direction M, and the third portion 113 extends along a second circumferential direction N. The first portion 111, the second portion 112, and the third portion 113 can be integrally bent and formed.

[0058] One end of the second portion 112 is connected to the first portion 111, and the other end is connected to the end of the first branch 141 closest to the first portion 111. The second portion 112 and the first branch 141 can be connected by welding. Because the first main input terminal 110 includes the second portion 112 extending along the first circumferential direction M, the circumferential length of the first branch 141 can be reduced, thereby making the volume of the first branch 141 smaller, reducing the difficulty of processing the first branch 141, and reducing processing waste during the processing of the first branch 141.

[0059] One end of the third portion 113 is connected to the first portion 111, and the other end is connected to the end of the second branch 142 closest to the first portion 111. The connection between the third portion 113 and the second branch 142 can be welded. Because the first main input terminal 110 includes the third portion 113 extending along the second circumferential direction N, the circumferential length of the second branch 142 can be reduced, thereby making the volume of the second branch 141 smaller. This reduces the difficulty in machining the second branch 142 and reduces processing waste during the machining of the second branch 142.

[0060] The second electrical connection portion 150 includes a third branch 151 and a fourth branch 152. The third branch 151 extends along a first circumferential direction M about the first axis 400, and the fourth branch 152 extends along a second circumferential direction N about the first axis 400. The second main input terminal 120 includes a fourth portion 121, a fifth portion 122, and a sixth portion 123. The fourth portion 121 extends along the first direction X. One end of the fifth portion 122 connects to an end of the fourth portion 121 along the first direction X, and the other end of the fifth portion 122 connects to an end of the third branch 151 proximal to the fourth portion 121. The sixth portion 123 connects to an end of the fourth portion 121 along the first direction X, and the other end of the sixth portion 123 connects to an end of the fourth branch 152 proximal to the fourth portion 121. The fifth portion 122 and the sixth portion 123 connect to a common end of the fourth portion 121. The fourth portion 121, the fifth portion 122, and the sixth portion 123 are integrally bent. In the above-mentioned structural arrangement of the first main input terminal 110, the circumferential length of the third branch 151 and the fourth branch 152 can be reduced, so that the overall volume of the third branch 151 and the fourth branch 152 can be smaller, thereby reducing processing waste during the processing of the third branch 151 and the fourth branch 152.

[0061] The third electrical connection portion 160 includes a fifth branch 161 and a sixth branch 162. The fifth branch 161 extends along a first circumferential direction M about the first axis 400, and the sixth branch 162 extends along a second circumferential direction N about the first axis 400. The third main input terminal 130 includes a seventh portion 131, an eighth portion 132, and a ninth portion 133. The seventh portion 131 extends along the first direction X. One end of the eighth portion 132 connects to an end of the seventh portion 131 along the first direction X, and the other end of the eighth portion 132 connects to an end of the fifth branch 161 proximal to the seventh portion 131. The ninth portion 133 connects to an end of the seventh portion 131 along the first direction X, and the other end of the ninth portion 133 connects to an end of the sixth branch 162 proximal to the seventh portion 131. The eighth portion 132 and the ninth portion 133 connect to a common end of the seventh portion 131. The seventh, eighth, and ninth portions 131, 132, and 133 are integrally bent. In the above structural arrangement of the third main input terminal 130 , the overall volume of the fifth branch 161 and the sixth branch 162 can be smaller, thereby reducing processing waste during the processing of the fifth branch 161 and the sixth branch 162 .

[0062] In this embodiment, the first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161, and the sixth branch 162 are each used to connect the first ends 210 of two windings 200. The first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161, and the sixth branch 162 collectively connect the first ends 210 of the twelve windings 200 of the motor 10. The fourth electrical connection portion 170 connects the second ends 220 of the twelve windings 200, forming a star connection of the twelve windings 200.

[0063] In this embodiment, at least one branch of the first electrical connection portion 140 and at least one branch of the second electrical connection portion 150 are stacked along the first direction X. Specifically, referring to Figures 2, 5, 9, and 10, the first branch 141 and the fourth branch 152 are at least partially stacked along the first direction X. This structural arrangement can reduce the overall space occupied by the first branch 141 and the fourth branch 152. Furthermore, at least one branch of the first electrical connection portion 140 and at least one branch of the third electrical connection portion 160 are stacked along the first direction X. Specifically, the first branch 141 and the sixth branch 162 are at least partially stacked along the first direction X. This structural arrangement can reduce the overall space occupied by the first branch 141 and the sixth branch 162.

[0064] Furthermore, in this embodiment, the third branch 151 and the sixth branch 162 are at least partially stacked along the first direction X, which can reduce the overall space occupied by the third branch 151 and the sixth branch 162. The third branch 151 and the second branch 142 are at least partially stacked along the first direction X, which can reduce the overall space occupied by the third branch 151 and the second branch 142. The fifth branch 161 and the second branch 142 are at least partially stacked along the first direction X, which can reduce the overall space occupied by the fifth branch 161 and the second branch 142. The fifth branch 161 and the fourth branch 152 are at least partially stacked along the first direction X, which can reduce the overall space occupied by the fifth branch 161 and the fourth branch 152.

[0065] In this embodiment, the first branch 141, the sixth branch 162, and the sixth portion 123 are sequentially stacked along the first direction X. This reduces the overall space occupied by the first branch 141, the sixth branch 162, and the sixth portion 123. Furthermore, the first branch 141, the sixth branch 162, and the fifth portion 122 are sequentially stacked along the first direction X, thereby reducing the overall space occupied by the first branch 141, the sixth branch 162, and the fifth portion 122. The fifth branch 161, the fourth branch 152, and the second portion 112 are sequentially stacked along the first direction X, thereby reducing the overall space occupied by the fifth branch 161, the fourth branch 152, and the second portion 112. The fifth branch 161, the fourth branch 152, and the first portion 111 are sequentially stacked along the first direction X, thereby reducing the overall space occupied by the fifth branch 161, the fourth branch 152, and the first portion 111. The third branch 151, the first branch 141, and the eighth portion 132 are sequentially stacked along the first direction X, thereby reducing the overall space occupied by the third branch 151, the first branch 141, and the eighth portion 132. The third branch 151, the first branch 141, and the ninth portion 133 are sequentially stacked along the first direction X, thereby reducing the overall space occupied by the third branch 151, the first branch 141, and the ninth portion 133.

[0066] Specifically, referring to Figures 2, 5, 9, and 10, in this embodiment, the first branch 141 includes a first connection terminal 1411 for electrically connecting to the first end 210 of the winding 200, the fourth branch 152 includes a second connection terminal 1521 for electrically connecting to the first end 210 of the winding 200, and the sixth branch 162 includes a third connection terminal 1621 for electrically connecting to the first end 210 of the winding 200. The second main input terminal 120 includes a fourth portion 121, a fifth portion 122, and a sixth portion 123 extending along a first direction X. The fourth portion 121 extends along the first direction X, the fifth branch 161 extends around a first circumferential direction M and connects to the third branch 151, and the sixth portion 123 extends around a second circumferential direction N and connects to the fourth branch 152. Along the first circumferential direction M, the first connection terminal 1411, the second connection terminal 1521, and the third connection terminal 1621 are all located between the first portion 111 and the fourth portion 121. The above structural arrangement enables the connection terminals electrically connected to different adjacent windings 200 to be arranged adjacent to each other, thereby facilitating electrical connection between the connection terminals and the windings 200 .

[0067] In this embodiment, the first connection terminal 1411, the second connection terminal 1521, and the third connection terminal 1621 are sequentially arranged adjacent to each other along the first circumferential direction M. This structural arrangement ensures that the arrangement order and arrangement direction of the first connection terminal 1411, the second connection terminal 1521, and the third connection terminal 1621 are consistent with the arrangement order and arrangement direction of the three windings 200 to which they are connected, further facilitating the connection between each connection terminal and each winding 200. Preferably, in this embodiment, the first connection terminal 1411, the second connection terminal 1521, and the third connection terminal 1621 are arranged in a circular array with the first axis 400 as the central axis, and the array angle is sixty degrees.

[0068] In this embodiment, the first branch 141, the third branch 151, and the fifth branch 161 are distributed along the first circumferential direction M, and the first branch 141, the third branch 151, and the fifth branch 161 are aligned along the first direction X. This solution can reduce the overall space occupied by the first branch 141, the third branch 151, and the fifth branch 161 along the first direction X. The second branch 142, the fourth branch 152, and the sixth branch 162 are distributed along the first circumferential direction M, and the second branch 142, the fourth branch 152, and the sixth branch 162 are aligned along the first direction X. This solution can reduce the overall space occupied by the second branch 142, the fourth branch 152, and the sixth branch 162 along the first direction X.

[0069] In this embodiment, the first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161, and the sixth branch 162 are all integrally formed from a sheet 184, and the thickness directions of the first branch 141, the second branch 142, the third branch 151, the fourth branch 152, the fifth branch 161, and the sixth branch 162 are all parallel to the first direction X. In this solution, the thickness of the remaining components of the conductive connection base 100 after removing the first main input terminal 110, the second main input terminal 120, and the third main input terminal 130 can be further reduced along the first direction X, thereby reducing the overall space occupied by the conductive connection base 100.

[0070] Since the specific connection method of the first branch 141, the third branch 151, and the fifth branch 161 can be the same, the structure and size of the first branch 141, the third branch 151, and the fifth branch 161 in this embodiment can all be the same. When manufacturing the first branch 141, the third branch 151, and the fifth branch 161, the same component can be manufactured first. Then, when the component is installed at the position of the first branch 141, the component becomes the first branch 141; when the component is installed at the position of the third branch 151, the component becomes the third branch 151; and when the component is installed at the arrangement position of the fifth branch 161, the component becomes the fifth branch 161.

[0071] Since the specific connection method of the second branch 142, the fourth branch 152, and the sixth branch 162 can be the same, the structure and size of the second branch 142, the fourth branch 152, and the sixth branch 162 in this embodiment can all be the same. When manufacturing the second branch 142, the fourth branch 152, and the sixth branch 162, a single component can be manufactured. Then, when the component is installed at the position of the second branch 142, the component becomes the second branch 142; when the component is installed at the position of the fourth branch 152, the component becomes the fourth branch 152; and when the component is installed at the arrangement position of the sixth branch 162, the component becomes the sixth branch 162.

[0072] Because the specific connection methods of the first, second, and third main input terminals 110, 120, and 130 can be the same, in this embodiment, the first, second, and third main input terminals 110, 120, and 130 all have the same structure and size. When manufacturing the first, second, and third main input terminals 110, 120, and 130, a single component can be manufactured. When this component is installed in the position of the first main input terminal 110, it becomes the first main input terminal 110; when this component is installed in the position of the second main input terminal 120, it becomes the second main input terminal 120; and when this component is installed in the position of the third main input terminal 130, it becomes the third main input terminal 130.

[0073] The specific placement of the fourth electrical connection portion 170 depends on specific needs. In this embodiment, referring to Figures 4-5 , the fourth electrical connection portion 170 is disposed inwardly of the first main input terminal 110, the second main input terminal 120, and the third main input terminal 130, near the first axis 400. Compared to a structural arrangement in which the fourth electrical connection portion 170 and at least one of the first electrical connection portion 140, the second electrical connection portion 150, and the third electrical connection portion 160 are stacked along the first direction X, this structural arrangement can further reduce the thickness of the remaining components of the conductive connection base 100, excluding the first main input terminal 110, the second main input terminal 120, and the third main input terminal 130, along the first direction X.

[0074] In this embodiment, the fourth electrical connection portion 170 includes four electrically connected connection pieces, arranged circumferentially around the first axis 400. The four connection pieces are a first connection piece 171, a second connection piece 172, a third connection piece 173, and a fourth connection piece 174. The first connection piece 171 includes a fourth connection terminal 1711, a fifth connection terminal 1712, and a sixth connection terminal 1713. The first connection terminal 1411 and the fourth connection terminal 1711 are arranged opposite each other, and the first connection terminal 1411 and the fourth connection terminal 1711 are used to electrically connect to the same winding 200. The second connection terminal 1521 and the fifth connection terminal 1712 are arranged opposite each other, and the second connection terminal 1521 and the fifth connection terminal 1712 are used to electrically connect to the same winding 200. The third connection terminal 1621 and the sixth connection terminal 1713 are arranged opposite each other, and the third connection terminal 1621 and the sixth connection terminal 1713 are used to electrically connect to the same winding 200. The first connecting piece 171 , the second connecting piece 172 , the third connecting piece 173 and the fourth connecting piece 174 are commonly connected to the second ends 220 of the twelve windings 200 , so that the second ends 220 of all windings 200 powered by the three-phase circuit of the motor stator are electrically connected to each other.

[0075] In other embodiments, the fourth electrical connection portion 170 may also include only two connecting pieces or only one connecting piece, which will not be described in detail here. Compared with the connection method of two connecting pieces or one connecting piece, providing four connecting pieces can simplify the process of the fourth electrical connection portion 170 and save raw materials.

The stator assembly 11 includes any of the above-described conductive connectors 100, a stator core 600, an insulating frame 230 secured to the stator core 600, and a plurality of windings 200 wound on the insulating frame 230. Each winding 200 is secured to the insulating frame 230, with adjacent windings 200 spaced apart and arranged relative to each other. That is, adjacent windings 200 are spaced apart directly from each other without insulating paper interposed therebetween, thereby reducing the material cost of the motor 10.

Each winding 200 is secured to an insulating frame 230, and each winding 200 includes a first end 210 and a second end 220 electrically connected to the busbar assembly 101.

[0078] The insulating frame 230 has a second clamping portion 231. After the first clamping portion 198 of the supporting component 190 is clamped with the second clamping portion 231 of the insulating frame 230, the first end 210 of each winding 200 is opposite to the various connection terminals of the first electrical connection portion 140, the second electrical connection portion 150 and the third electrical connection portion 160 in the first direction X, and the second end 220 of each winding 200 is opposite to the various connection terminals of the fourth electrical connection portion 170 in the second direction.

[0079] The insulating frame 230, conductive connection base 100, and winding 200 of the motor 10 are all disposed within a housing 300. The housing 300 includes an end cap 310 having an opening 311. The first main input terminal 110 and the first support portion 191 extend out of the housing 300 through the opening 311. Specifically, the end cap 310 includes three openings 311. The first main input terminal 110 and the first support portion 191 extend out of the housing 300 through the first opening 311. The second main input terminal 120 and the second support portion 192 extend out of the housing 300 through the second opening 311. The third main input terminal 130 and the third support portion 193 extend out of the housing 300 through the third opening 311.
