Description

Rotating Electric Machine and Method of Manufacturing Rotating Electric Machine Cross - Reference to Related Applications

[0001] This application is based on Japanese Application No. 2024 - 184329 filed on October 18, 2024, claims the benefit of its priority, and all the contents of the patent application are incorporated herein by reference.

[0002] The technology of the present disclosure relates to a rotating electric machine and a method of manufacturing a rotating electric machine.

[0003] Conventionally, there is a rotating electric machine including a stator having an annular stator core and a rotor accommodated inside the stator core in the radial direction. Among this type of rotating electric machine, there is one in which the stator is composed of a plurality of stator constituent units (see, for example, Japanese Patent No. 5502115). Each stator constituent unit includes a plurality of core constituent members constituting the stator core, a winding having a plurality of winding portions wound around the plurality of core constituent members, and an insulator insulating the stator core and the winding. The insulator has a plurality of insulating portions attached to the plurality of core constituent members and insulating the core constituent members and the winding portions, and a connecting portion formed along the circumferential direction of the stator and connecting the plurality of insulating portions. Each connecting portion is disposed on one side in the axial direction of the stator.

[0004] As a result of the inventors' detailed examination, the following problem has been found. That is, when the inner diameter of each connecting portion is smaller than the outer diameter of the rotor, in the rotor accommodation step of accommodating the rotor inside the stator core in the radial direction of the stator core, since it is necessary to accommodate the rotor inside the stator core from the side opposite to the connecting portion in the axial direction of the stator (that is, the other side in the axial direction of the stator), there are restrictions on the direction of assembling the rotor to the stator.

[0005] On the other hand, if the inner diameter of each connecting part is larger than the outer diameter of the rotor, the rotor can be assembled to the stator from both axial sides of the stator without any constraints on the direction of assembly of the rotor to the stator. However, since each connecting part is positioned to overlap with the stator core in the axial direction of the stator, when assembling the first stator component unit to the second stator component unit from one axial side of the stator, the core components of the first stator component unit interfere with the connecting parts of the second stator component unit, making it impossible to ensure the assembly of the stator.

[0006] The technology disclosed herein provides a rotating electric machine and a method for manufacturing a rotating electric machine that allows the rotor to be assembled to the stator from both axial sides of the stator while ensuring the ease of assembly of the stator.

[0007] A first aspect of the technology of the present disclosure is a rotating electric machine comprising a stator having an annular stator core and a rotor housed radially inward of the stator core, wherein the stator is composed of a plurality of stator component units, including a first stator component unit and a second stator component unit, each of which comprises a plurality of core component members constituting the stator core, a winding having a plurality of winding portions wound around the plurality of core component members, a plurality of insulating portions mounted on the plurality of core component members to insulate the core component members from the winding portions, and a connecting portion formed along the circumferential direction of the stator to connect the plurality of insulating portions. The rotating electric machine comprises an insulator and a connecting portion, each of which is positioned to overlap with the stator core in the axial direction of the stator, the first stator unit is a stator unit assembled to the second stator unit from one side in the axial direction of the stator, and the connecting portion of the first stator unit has a movable portion that moves the core component of the first stator unit from a position retracted radially outward of the stator than the connecting portion of the second stator unit toward a position aligned on the same circumference as the core component of the second stator unit toward the radially inward side of the stator.

[0008] A second aspect of the technology of the present disclosure is a method for manufacturing a rotating electric machine according to the first aspect, comprising: a stator assembly step of assembling the stator by assembling the first stator component unit to the second stator component unit from one axial side of the stator; and a rotor housing step of housing the rotor radially inward of the stator core, wherein the stator assembly step includes using the movable part to move the core component of the first stator component unit radially inward of the stator from a position retracted radially outward of the stator than the connecting part of the second stator component unit toward a position aligned on the same circumference as the core component of the second stator component unit.

[0009] The technology of this disclosure provides a rotating electric machine and a method for manufacturing a rotating electric machine that allows the rotor to be assembled to the stator from both axial sides of the stator while ensuring the ease of assembly of the stator.

[0011] An embodiment of the technology described herein will be described below.

[0012] As shown in Figure 1, the stator 10 according to this embodiment is a so-called split-core type stator. The basic configuration of a split-core type stator is described in Patent Document 1. The stator 10 is an improvement on the stator described in Patent Document 1. The stator 10 is applied to an inner rotor type brushless motor M. That is, the stator 10 is equipped with a stator core 20, which will be described later, and a rotor 11 is rotatably housed radially inside the stator core 20, and the stator 10 and rotor 11 constitute the brushless motor M. The brushless motor M is an example of a "rotating electric machine" according to the technology of this disclosure.

[0013] The brushless motor M according to this embodiment is a brushless motor in which, when n is a natural number of 2 or more, the number of magnetic poles of the rotor 11 is 2 × n and the number of slots of the stator 10 is 3 × n. In the example shown in Figure 1, n = 4, and the brushless motor M is an 8-pole, 12-slot brushless motor with 8 magnetic poles on the rotor 11 and 12 slots on the stator 10. The case of an 8-pole, 12-slot brushless motor will be described below as an example.

[0014] The stator 10 is composed of multiple stator component units 12 for the U-phase, V-phase, and W-phase. The stator 10 has one stator component unit 12 for each phase. That is, the total number of multiple stator component units 12 is three.

[0015] In the following explanation, when distinguishing between multiple stator configuration units 12, the U-phase stator configuration unit 12 will be referred to as "stator configuration unit 12U," the V-phase stator configuration unit 12 as "stator configuration unit 12V," and the W-phase stator configuration unit 12 as "stator configuration unit 12W."

[0016] Each stator component unit 12 comprises a plurality of core components 14, a winding 16, and an insulator 18. The number of plurality of core components 14 in each stator component unit 12 is four. When the plurality of stator component units 12 are combined, the plurality of core components 14 form an annular stator core 20 (see Figure 2). Each core component 14 has a toothed portion that protrudes radially inward from the stator 10. The space between adjacent toothed portions in the circumferential direction of the stator 10 is formed as a slot.

[0017] The winding 16 has a plurality of winding sections 30 wound around the teeth of each core component 14, a plurality of jumper wires 32 (see Figure 2) connecting the plurality of winding sections 30 to each other, and a pair of terminal sections (not shown) that are both ends of the winding 16. The terminal sections are the starting terminal section or the ending terminal section of the winding 16. The terminal sections are connected, for example, to a circuit board (not shown) provided by the brushless motor M.

[0018] The insulator 18 is made of resin. The insulator 18 has a plurality of insulating parts 36 and a connecting part 38. Each insulating part 36 is attached to the core component 14 and insulates the core component 14 from the winding part 30. The connecting part 38 is formed in an annular shape along the circumferential direction of the stator 10 and connects the plurality of insulating parts 36. In each stator component unit 12, the jumper wires 32 (see Figure 2) are routed along the connecting part 38. In each stator component unit 12, the plurality of core components 14 are arranged with a gap between adjacent core components 14 that allows for the arrangement of two core components 14 of the other phase.

[0019] Stator component unit 12W is assembled to stator component unit 12V from one axial side of stator 10, and stator component unit 12U is assembled to stator component units 12V and 12W from one axial side of stator 10. Stator component unit 12U is an example of the "first stator component unit" according to the technology of this disclosure, stator component unit 12W is an example of the "second stator component unit" according to the technology of this disclosure, and stator component unit 12V is an example of the "third stator component unit" according to the technology of this disclosure.

[0020] As shown in Figure 2, the connecting portion 38 of the stator component unit 12U (hereinafter referred to as "connecting portion 38U") and the connecting portion 38 of the stator component unit 12W (hereinafter referred to as "connecting portion 38W") are positioned to overlap in the radial direction of the stator 10. Specifically, the connecting portion 38U is positioned in the axial direction of the stator 10 at a position corresponding to the connecting portion 38W (i.e., the same position in the axial direction of the stator 10), and the connecting portion 38U is positioned radially outward of the stator 10 relative to the connecting portion 38W. In other words, the connecting portion 38U is positioned in a position that is concentric with the connecting portion 38W when viewed from above, and appears to be concentric when viewed from the radial direction. Furthermore, the connecting portions 38U, 38W, and the connecting portion 38 of the stator component unit 12V (hereinafter referred to as "connecting portion 38V") are positioned separately on both sides of the stator 10 in the axial direction. Specifically, the connecting parts 38U and 38W are located on one axial side of the stator 10, and the connecting part 38V is located on the other axial side of the stator 10.

[0021] The inner diameters of the connecting portions 38U, 38V, and 38W are larger than the outer diameter D of the rotor 11. Furthermore, the connecting portions 38U, 38V, and 38W are positioned to overlap with the stator core 20 in the axial direction of the stator 10. In other words, the connecting portions 38U, 38V, and 38W are positioned to appear to overlap with the stator core 20 when viewed from the axial direction of the stator 10. Specifically, the inner diameters of the connecting portions 38U, 38V, and 38W are larger than the inner diameter of the stator core 20 and smaller than the outer diameter of the stator core 20.

[0022] In this embodiment, since the inner diameters of the connecting portions 38U, 38V, and 38W are larger than the outer diameter D of the rotor 11, there are no restrictions on the direction in which the rotor 11 is assembled to the stator 10, and the rotor 11 can be assembled to the stator 10 from both axial sides of the stator 10. However, if the connecting portions 38U, 38V, and 38W are positioned to overlap with the stator core 20 in the axial direction of the stator 10, there is a risk that the core component 14 of the stator component unit 12U (hereinafter referred to as "core component 14U") will interfere with the connecting portion 38W of the stator component unit 12W when assembling the stator component unit 12U to the stator component unit 12W from one axial side of the stator 10. If the core component 14U interferes with the connecting portion 38W, there is a risk that the assembly of the stator 10 cannot be ensured. Therefore, in this embodiment, the following structure is adopted in order to ensure the assembly of the stator 10.

[0023] As shown in Figure 3, in the stator configuration unit 12U, the connecting portion 38U has a movable portion 40 that moves the core component 14U. The movable portion 40 is configured to move the core component 14U from a position that is set back radially outward from the connecting portion 38W of the stator configuration unit 12W to a position that is aligned radially inward from the stator 10 with the core components 14V and 14W of the stator configuration units 12V and 12W.

[0024] In Figures 1 and 3, the movable part 40 positions the core component 14U in a position set back from the connecting part 38W, while in Figure 2, the movable part 40 positions the core component 14U to be aligned on the same circumference as the core components 14V and 14W. When the core component 14U is positioned in a position set back from the connecting part 38W, the core component 14U is located radially outward from the connecting part 38W of the stator 10, thus avoiding interference between the core component 14U and the connecting part 38W, and the stator component unit 12U can be assembled to the stator component units 12V and 12W from one axial side of the stator 10. On the other hand, when the core component 14U is positioned to be aligned on the same circumference as the core components 14V and 14W, the core component 14U is positioned between the core components 14V and 14W, and the core components 14U, 14V, and 14W form an annular stator core 20.

[0025] As shown in Figures 4 to 6, the connecting portion 38U has a connecting body portion 42 formed along the circumferential direction of the insulator 18U. The movable portion 40 is provided on the radially outer side of the connecting body portion 42 and has a pair of support portions 44 that elastically support the insulating portion 36U that insulates the core component 14U relative to the connecting body portion 42. The pair of support portions 44 are provided on both sides of the insulator 18U in the circumferential direction relative to the insulating portion 36U. Each support portion 44 is formed in an arm shape extending from the connecting body portion 42 and has flexibility (i.e., elasticity) in the radial direction of the insulator 18U. The pair of support portions 44 extend along the tangential direction of the insulator 18U. It is desirable that the radius of curvature of the curved portion 44A (see Figure 6) connecting each support portion 44 and the connecting body portion 42 be sufficient to prevent cracking of the curved portion 44A. The pair of support portions 44 are positioned offset in the axial direction of the insulator 18U relative to the connecting body portion 42 (see Figure 5).

[0026] The connecting portion 38U has a fixing portion 46 (see Figure 7) that fixes the position of the core component 14U when the core component 14U moves to a position where it is aligned on the same circumference as the core components 14V and 14W. The fixing portion 46 is a so-called snap-fit ​​structure and has a locking portion 48 formed on the connecting body portion 42 and a locked portion 50 formed on the support portion 44. Corresponding to the fact that the pair of support portions 44 are provided at a position offset in the axial direction of the insulator 18 relative to the connecting body portion 42 (see Figure 5), the locked portion 50 is provided at a position offset in the axial direction of the insulator 18U relative to the locking portion 48.

[0027] As the core component 14U moves radially inward from the radially outer side of the insulator 18U toward a position where it aligns with the core components 14V and 14W on the same circumference, the locking portion 50 moves over the locking portion 48 from the radially outer side of the insulator 18U. When the core component 14U reaches the position where it aligns with the core components 14V and 14W on the same circumference, the locking portion 50 is locked to the locking portion 48 from the radially inner side of the insulator 18U. This fixes the core component 14U in a position where it aligns with the core components 14V and 14W on the same circumference. When the fixing by the fixing portion 46 is released, the pair of support portions 44 are in a free state (i.e., in their original shape without elastic deformation), and the core component 14U is positioned behind the connecting portion 38W.

[0028] As shown in Figure 8, the manufacturing method of the rotating electric machine according to this embodiment comprises a stator component assembly step, a stator assembly step, and a rotor housing step. The stator component assembly step is a step of assembling each of the multiple stator component units 12 individually. The stator assembly step is a step of assembling stator component unit 12W to stator component unit 12V from one axial side of the stator 10, and assembling stator component unit 12U to stator component units 12V and 12W from one axial side of the stator 10.

[0029] In the stator assembly process, the fixing by the fixing part 46 is released, so that the core component 14U is positioned radially outward from the connecting part 38W of the stator 10, thereby preventing interference between the core component 14U and the connecting part 38W. Therefore, the stator component unit 12U can be assembled to the stator component units 12V and 12W from one axial side of the stator 10. Subsequently, after assembling the stator component unit 12U to the stator component units 12V and 12W, the movable part 40 is used to move the core component 14U radially inward from the position retracted from the connecting part 38W to a position where it is aligned on the same circumference as the core components 14V and W. As a result, the core component 14U is positioned between the core components 14V and 14W, and the core components 14U, 14V and 14W form an annular stator core 20. Then, the support portion 44 is fixed to the connecting body portion 42 using the fixing portion 46, and the core component 14U is fixed in a position where it is aligned on the same circumference as the core components 14V and 14W. The rotor housing step is the step of housing the rotor 11 radially inward of the stator core 20.

[0030] Next, the effects of this embodiment will be described.

[0031] As described in detail above, in this embodiment, the connecting portions 38U, 38V, and 38W are positioned to overlap with the stator core 20 in the axial direction of the stator 10, and the inner diameters of each connecting portion 38U, 38V, and 38W are larger than the outer diameter D of the rotor 11. Therefore, the rotor 11 can be assembled to the stator 10 from both sides in the axial direction of the stator 10 without any constraints on the assembly direction of the rotor 11 to the stator 10.

[0032] Furthermore, in the stator configuration unit 12U, the connecting portion 38U has a movable portion 40, and the movable portion 40 is configured to move the core component 14U from a position that is set back radially outward from the connecting portion 38W of the stator configuration unit 12W to a position that is aligned on the same circumference as the core components 14V and 14W of the stator configuration units 12V and 12W, towards the radially inward side of the stator 10.Therefore, when the core component 14U is positioned set back from the connecting portion 38W using the movable portion 40, the core component 14U is located radially outward from the connecting portion 38W of the stator 10, so interference between the core component 14U and the connecting portion 38W can be avoided.As a result, the stator configuration unit 12U can be assembled to the stator configuration units 12V and 12W from one side in the axial direction of the stator 10, so that the ease of assembly of the stator 10 can be ensured.

[0033] Furthermore, after assembling the stator component unit 12U to the stator component units 12V and 12W, the movable part 40 can be used to move the core component 14U radially inward of the stator 10 so that it is aligned with the core components 14V and 14W on the same circumference. As a result, the core component 14U is positioned between the core components 14V and 14W, so that the core components 14U, 14V and 14W can form an annular stator core 20.

[0034] Furthermore, the movable part 40 has a pair of support parts 44 that support the insulating part 36U relative to the connecting body part 42. Each support part 44 is formed in the shape of an arm extending from the connecting body part 42 and is flexible in the radial direction of the stator 10. Therefore, with a simple configuration, the core component 14U can be moved from a position set back from the connecting part 38W to a position where it is aligned on the same circumference as the core components 14V and 14W.

[0035] Furthermore, the connecting portion 38U has a fixing portion 46 that fixes the position of the core component 14U when the core component 14U moves to a position where it is aligned on the same circumference as the core components 14V and 14W. Therefore, by fixing the position of the core component 14U using the fixing portion 46, the core component 14U can be fixed to a position where it is aligned on the same circumference as the core components 14V and 14W.

[0036] Furthermore, the connecting portion 38U of the stator component unit 12U and the connecting portion 38W of the stator component unit 12W are positioned to overlap in the radial direction of the stator 10. Therefore, compared to, for example, the case where the connecting portion 38U and the connecting portion 38W are positioned to overlap in the axial direction of the stator 10, the axial length of the stator 10 can be shortened.

[0037] Furthermore, since the connecting portions 38U and 38W can be separated in the range where they overlap with the stator core 20 in the axial direction of the stator 10 (i.e., the range from the inner diameter to the outer diameter of the stator core 20), a distance can be secured between the jumper wire 32 (hereinafter referred to as "jumper wire 32U") routed along the connecting portion 38U and the jumper wire 32 (hereinafter referred to as "jumper wire 32W") routed along the connecting portion 38W (see Figure 2). This ensures the voltage withstand capability of the jumper wires 32U and 32W.

[0038] Furthermore, the connecting sections 38U and 38W and the connecting section 38V are arranged separately on both sides of the stator 10 in the axial direction. Therefore, a sufficient distance can be secured between the jumper wires 32U and 32W and the jumper wire 32 (hereinafter referred to as "jumper wire 32V") which is wired along the connecting section 38V (see Figure 2). This ensures the voltage withstand capability of the jumper wire 32V.

[0039] Next, a modified example of this embodiment will be described.

[0040] In the above embodiment, the movable part 40 has a pair of support parts 44, but the shape of the pair of support parts 44 is not limited to the above embodiment. For example, as shown in FIG. 9, the pair of support parts 44 may have a shape that increases the amount of movement in the radial direction of the insulator 18U compared to the above embodiment. Also, for example, as shown in FIG. 10, the pair of support parts 44 may have a shape that reduces the amount of movement in the radial direction of the insulator 18U compared to the above embodiment and increases the length along the circumferential direction of the insulator 18U.

[0041] Also, as shown in FIG. 11, the pair of support parts 44 may have a shape in which a bent portion is added to the above embodiment. Also, as shown in FIG. 12, the pair of support parts 44 may have a shape that further reduces the amount of movement in the radial direction of the insulator 18U compared to the above embodiment.

[0042] In the above embodiment, the stator 10 is applied to a brushless motor with n = 4 (that is, a 8-pole 12-slot brushless motor), but it may be applied to a brushless motor with n = 2 (that is, a 4-pole 6-slot brushless motor), or a brushless motor with n = 3 (that is, a 6-pole 9-slot brushless motor), or a brushless motor with n = 5 (that is, a 10-pole 15-slot brushless motor), or a brushless motor with n = 6 (that is, a 12-pole 18-slot brushless motor), or a brushless motor with n = 7 (that is, a 14-pole 21-slot brushless motor). Also, the stator 10 may be applied to a brushless motor with n ≧ 8.

[0043] Also, in the above embodiment, the U phase, V phase, and W phase assigned to the plurality of stator configuration units 12 may be other than the above.

[0044] As described above, one embodiment of the technology of the present disclosure has been described, but the present invention is not limited to the above, and it is needless to say that various modifications can be made without departing from the gist thereof.
