Description

Technical Field

[0001] This application relates to the field of motor technology, and in particular to an insulating frame module, a stator core module, a stator, a motor, and a compressor. Background Technology

[0002] The insulating frame mainly serves to insulate and support the motor windings and core. There are many types of motor insulating frames, mainly three types: traditional, integral, and separate. The traditional insulating frame is the most common type, which requires the use of insulating slot paper to isolate the windings and stator core, and consists of two insulating frames, upper and lower. The integral type is based on the traditional frame, extending the slot insulation interlocking structure to replace the use of insulating slot paper, reducing the number of manufacturing steps. The separate frame is based on the integral frame, which is divided according to the number of stator core slots to improve the slot fill factor and facilitate stator winding.

[0003] The calculation of the effective slot area of ​​a motor requires subtracting the area occupied by the slot insulation structure. Therefore, the thickness of the slot insulation is closely related to the slot area. For a split insulation frame, the upper and lower frames need to work together to fix the stator core in the middle. To ensure the assembly stability of the stator winding and the core and to meet process requirements, the slot insulation structure needs to have a certain thickness, which results in a smaller slot area for the split frame. Summary of the Invention

[0004] The purpose of this application is to provide an insulating frame module, a stator core module, a stator, a motor, and a compressor. The insulating frame module works in conjunction with the stator core module, which increases the slot area of ​​the separate frame compared to the traditional separate frame.

[0005] To this end, in a first aspect, embodiments of this application provide an insulating frame module that cooperates with a stator core module of a motor. The stator core module is provided with a recessed portion. The insulating frame module includes a first insulating frame and a second insulating frame located on both axial sides of the stator core module.

[0011] In one possible implementation, the first insulating frame further includes a first outer wall connected to the first slot insulating structure. The first outer wall is provided with inlet and outlet slots and also has a plurality of protrusions spaced apart. The plurality of protrusions are used to fix the winding inlet and winding outlet.

[0012] In one possible implementation, the second insulating frame further includes a second outer wall connected to the second slot insulating structure, the second outer wall being provided with snaps for the aggregation and fixation of multiphase windings.

[0013] In one possible implementation, the stator core module has recesses on both sides, and the second groove has two joints protruding toward the two recesses respectively, with the first groove covering the joints.

[0016] Fourthly, embodiments of this application provide an electric motor, including a rotor and the stator described above, wherein the stator is disposed on the outer or inner circumferential side of the rotor, and the thickness of the rotor core module of the rotor is greater than the thickness of the stator core module of the stator.

[0017] Fifthly, embodiments of this application provide a compressor, including the motor described above.

[0018] According to the embodiments of this application, an insulating frame module, a stator core module, a stator, a motor, and a compressor are provided.

This eliminates the need for additional insulating groove paper, reduces manufacturing steps, and increases the groove area of ​​the insulating frame module compared to traditional separate frames. Meanwhile, the stator core is provided with a recessed portion, which provides sufficient margin for the joint, making the overall thickness of the first slot insulation structure and the second slot insulation structure thinner, and making the joint transition smooth. It also reduces the material used in the stator core module and lowers the manufacturing cost of the motor. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figure 1 As shown, Figure 1This diagram shows an exploded view of an insulating frame module and a stator core module provided in an embodiment of this application. The embodiment of this application provides an insulating frame module 1 that cooperates with a stator core module 2 of a motor. The stator core module 2 is provided with a recessed portion 21. The insulating frame module 1 includes a first insulating frame 11 and a second insulating frame 12 located on both radially sides of the stator core module 2. The first insulating frame 11 includes a first slot insulating structure 111 having a first slot 1111, and the second insulating frame 12 includes a second slot insulating structure 121 having a second slot 1211. Either the first slot 1111 or the second slot 1211 is provided with a connecting portion 13 protruding towards the recessed portion 21 of the stator core module 2. The other of the first slot 1111 and the second slot 1211 covers the connecting portion 13.

[0033] It should be understood that the insulating frame module 1 includes a first insulating frame 11 and a second insulating frame 12, which are located at opposite ends of the stator core module 2 along the axial direction. The first insulating frame 11 includes a first slot insulating structure 111, and the second insulating frame 12 includes a second slot insulating structure 121. The first slot insulating structure 111 has a first slot 1111 adapted to the stator core module 2, and the second slot insulating structure 121 has a second slot 1211 adapted to the stator core module 2. During installation, the first slot 1111 of the first slot insulating structure 111 is fitted onto one end of the stator core module 2 along the axial direction, and the second slot 1211 of the second slot insulating structure 121 is fitted onto the other end of the stator core module 2 along the axial direction, with the first slot 1111 and the second slot 1211 in contact, thereby improving the insulation effect on the stator core module 2.

[0034] Furthermore, the stator core module 2 is provided with a recessed portion 21. Either the first slot 1111 or the second slot 1211 is provided with a connecting portion 13 protruding from the recessed portion 21 towards the stator core module 2. The other slot 1111 or the second slot 1211 covers the connecting portion 13. The connecting portion 13 engages with the recessed portion 21, and the other slot 1111 or the second slot 1211 covers the connecting portion 13, allowing the first insulating frame 11 and the second insulating frame 12 to seal and enclose the stator core module 2. This eliminates the need for additional insulating slot paper, reducing manufacturing steps and increasing the slot area of ​​the insulating frame module 1 compared to traditional separate frames. Simultaneously, the recessed portion 21 in the stator core module 2 provides sufficient allowance for the connecting portion 13, facilitating a smooth transition. This results in a thinner overall thickness of the first slot insulating structure 111 and the second slot insulating structure 121, reducing the material used in the stator core module 2 and lowering the motor manufacturing cost.

[0035] In some alternative embodiments, two stator core modules 2 are provided along the recess 21, with the two located on opposite sides of the stator core module 2 and the openings of the two recesses 21 facing away from each other.

[0036] In one example, the first groove 1111 protrudes towards the recess 21 with two joints 13. The two joints 13 are located at one end of the first groove 111 facing the stator core module 2 and on the inner wall of the first groove 1111. The thickness of the joints 13 is the same as the depth of the recess 21, making the joints 13 engage with the recess 21 more tightly. During installation, multiple stator laminations are first stacked, forming two recesses 21. Then, the first groove 1111 is fitted onto one axial end of the stator core module 2, so that the two joints 13 engage with the two recesses 21 respectively. Then, the second groove 1211 is fitted onto the other axial end of the stator core module 2, so that the second groove 1211 covers the joints 13, thereby playing a fixing role and ensuring that the stator core module 2 is completely wrapped by the first groove insulation structure 111 and the second groove insulation structure 121.

[0037] In one example, the second slot 1211 has two protruding joints 13 at one end facing the stator core module 2. The thickness of the joints 13 is the same as the depth of the recess 21. The two joints 13 are located on the inner wall of the second slot 1211 and protrude from the second slot 1211. During installation, multiple stator laminations are first stacked to form two recesses 21. Then, the second slot 1211 is fitted onto one axial end of the stator core module 2, so that the two joints 13 are respectively engaged with the two recesses 21. Then, the second slot 1211 is fitted onto the other axial end of the stator core module 2, so that the first slot 1111 covers the joints 13, thereby playing a fixing role and ensuring that the stator core module 2 is completely wrapped together by the first slot insulation structure 111 and the second slot insulation structure 121.

[0038] In one example, the first groove 1111 has a joint 13 protruding from one end toward the stator core module 2. The joint 13 is located on one inner wall of the first groove 1111. The second groove 1211 has another joint 13 protruding from one end toward the stator core module 2. The other joint 13 is located on one inner wall of the second groove 1211. The thickness of the two joints 13 is the same as the depth of the two recesses 21. During installation, multiple stator laminations are first stacked, forming two recessed portions 21. Then, the first groove 1111 or the second groove 1211 is fitted onto one end of the stator core module 2, and the other second groove 1211 or the first groove 1111 is fitted onto the other end of the stator core module 2, so that both joints 13 are engaged with the stator core module 2. The joint 13 at the first groove 1111 is covered by the second groove 1211, and the joint 13 at the second groove 1211 is covered by the first groove 1111, thereby playing a fixing role and ensuring that the stator core module 2 is completely wrapped together by the first groove insulation structure 111 and the second groove insulation structure 121.

Figure 1 , Figure 3 This image shows a front view of a second insulating frame provided in an embodiment of this application. Figure 1 In some optional embodiments, the joint 13 is a rectangular block disposed in the first groove 1111 and / or the second groove 1211. The joint 13 is a rectangular block and the width of the joint 13 is smaller than the width of the first groove 1111 and the width of the joint 13 is also smaller than the width of the second groove 1211. The stator core module 2 includes a yoke 22 and a tooth 23 connected to each other. When the joint 13 is disposed in the form of a rectangular block, the recess 21 of the stator core module 2 is also rectangular and located at the tooth 23.

Figure 2 , Figure 5 This image shows a front view of a second insulating frame provided in an embodiment of this application. Figure 2 In some alternative embodiments, the joint 13 extends along the outer contour of the first groove 1111 and / or the second groove 1211, and the joint 13 is located on the inner wall of the first groove 1111 and / or the second groove 1211. In this case, the recess 21 of the stator core module 2 extends not only to the tooth 23 but also toward the yoke 22.

[0041] Reference Figures 2-7 , Figure 6This figure shows a top view of a stator core module provided in an embodiment of this application. Figure 7 This diagram illustrates the structure of a stator core module according to an embodiment of this application. In some optional embodiments, the first slot 1111 or the second slot 1211 has an axial length of H1, and the joint 13 has an axial length of H2, satisfying the following condition: 0.3≤H2 / H1≤0.6.

[0042] The stator core module 2 has an axial length of 2H1. Based on the length of the stator core module 2, the lengths of the first slot 1111 and the second slot 1211 can be determined. The axial lengths of the first slot 1111 and the second slot 1211 are equal, i.e., H1 respectively. The axial length 2H1 of the stator core module 2 is related to the recess 21 of the stator core module 2. The recess 21 of the stator core module 2 is related to the joint 13. Therefore, either the first slot 1111 or the second slot 1211 is related to the joint 13 and satisfies 0.3≤H2 / H1≤0.6. When 0.3 ≤ H2 / H1 ≤ 0.6, the magnetic flux density of the stator core module 2 is more reasonable, thus ensuring motor efficiency and simultaneously improving the stability and insulation of the assembly between the stator core module 2 and the joint 13, reducing processing difficulty. When H2 / H1 is greater than 0.6, the motor iron loss increases; when H2 / H1 is less than 0.3, the magnetic field strength inside the motor is uneven. Preferably, 0.36 ≤ H2 / H1 ≤ 0.56 further makes the magnetic flux density of the stator core module 2 more reasonable, improving motor efficiency, further enhancing the stability and insulation of the assembly between the stator core module 2 and the joint 13, and reducing processing difficulty.

[0043] In some optional embodiments, the axial length of the stator core module 2 is 2*H1, the axial length of the joint 13 is H2, and the thickness of the joint 13 is W, satisfying the following condition: 29≤(2*H1-H2) / W≤41. When 29≤(2*H1-H2) / W≤41, the processing difficulty of the first slot insulation structure 111, the second slot insulation structure 121, and the stator core module 2 is reduced, improving work efficiency; when (2*H1-H2) / W is less than 29, the thickness W of the joint 13 is larger, and the thickness of the recess 21 of the stator core module 2 increases accordingly, which will increase the iron loss of the motor and reduce the motor efficiency; when (2*H1-H2) / W is greater than 41, the thickness of the joint 13 is smaller, which will increase the processing difficulty and reduce the assembly stability of the stator core module 2 and the joint 13. Preferably, 29.68≤(2*H1-H2) / W≤40.26, further reducing the processing difficulty of the first slot insulation structure 111 and the second slot insulation structure 121 with the stator core module 2, and further improving work efficiency.

[0044] In some optional embodiments, the stator core module 2 includes an interconnected yoke 22 and a tooth 23. The width of the tooth 23 is T, and the thickness of the joint 13 is W, satisfying the following condition: 0.08 ≤ W / T ≤ 0.11. When the width T of the tooth 23 in the stator core module 2 remains constant, a W / T greater than 0.11 will affect the magnetic flux density distribution of the stator core module 2, increasing iron loss and reducing motor operating efficiency. A W / T less than 0.08 will increase the processing difficulty of the first insulating frame 11 and / or the second insulating frame 12, and reduce the stability of the entire motor assembly.

[0045] Reference Figure 8 and Figure 9 , Figure 8 This diagram illustrates the structure of a first insulating frame according to an embodiment of this application. Figure 9 This diagram shows a front view of a first insulating frame provided in an embodiment of this application. In some optional embodiments, the first insulating frame 11 further includes a first outer wall 112 connected to a first slot insulating structure 111. The first outer wall 112 is provided with inlet / outlet slots 1121 and a plurality of spaced-apart bosses 1122 for fixing winding inlets and outlets. The plurality of bosses 1122 are divided into two groups, with the two groups of bosses 1122 located on both sides of the inlet / outlet slots 1121, and the plurality of bosses 1122 in each group arranged at intervals along the height direction of the first outer wall 112.

[0046] The first insulating frame 11 also includes a first outer wall 112 and a first inner wall 113. The first outer wall 112 and the first inner wall 113 are both located at the end of the first slot insulating structure 111 opposite to the stator core module 2, and are integrally formed with the first slot insulating structure 111. The first outer wall 112 is provided with an inlet / outlet slot 1121, which guides the winding of each phase. Furthermore, in order to reduce the winding path and winding amount of the inlet / outlet wires, the inlet / outlet slot 1121 is located at the radial center line of the first outer wall 112. The first outer wall 112 has multiple protrusions 1122 on the side opposite to the first inner wall 113. The multiple protrusions 1122 are divided into two groups, and the two groups of protrusions 1122 are located on both sides of the inlet / outlet groove 1121 respectively. The multiple protrusions 1122 in each group are arranged at intervals along the height direction of the first outer wall 112. In one example, there are six protrusions 1122 and they are divided into two groups. Each group of protrusions 1122 has three protrusions, and the two groups of protrusions 1122 are located on both sides of the inlet / outlet groove 1121 and arranged at intervals.

[0047] Three-phase winding bosses 1122 are provided on both sides of the inlet / outlet slot 1121 to accommodate the arrangement of the inlet and outlet wires of any phase winding, thereby improving the applicability of the mold. The bosses 1122 on both sides fix the position of the inlet and outlet wires of each phase winding. By using the wires at different heights to separate the three-phase wires, each phase winding is fixed, making the winding wire arrangement more neat and preventing the wires of different phase windings from crossing together.

[0048] Furthermore, the height difference x between the bosses is greater than the winding wire diameter y. For a three-phase motor, the winding output wires are arranged from bottom to top. When the winding sequence starts from phase C and ends at phase A, the boss of phase A is at the top. When the winding sequence starts from phase A and ends at phase C, the boss of phase C is at the top.

[0049] Taking the winding of phase A as an example, during winding, the phase A winding enters the slot 1121 from one side in the direction of winding. The uppermost boss 1122 fixes the entry position and starts winding in the tooth section. After winding is completed, the winding exits from the other side of the slot 1121 in the same direction. The exit position is then fixed by the other boss 1122 on the uppermost side. Since the first insulating frame 11 and the second insulating frame 12 are both universal, the winding direction can be clockwise or counterclockwise, and it is not limited to the winding material. It can be copper wire or aluminum wire.

[0050] With a fixed number of motor phases, motors with more slots have more winding outputs. The arrangement of slots 1121 and bosses 1122 reduces the complexity of the design of winding bosses 1122 for each phase winding and reduces the processing and manufacturing difficulty of the insulation frame module 1.

[0051] Reference Figures 2-5 In some optional embodiments, the second insulating frame 12 further includes a second outer wall 122 connected to the second slot insulating structure 121, the second outer wall 122 being provided with snap fasteners 1221 for the aggregation and fixation of multiphase windings.

[0052] The second insulating frame 12 also includes a second outer wall 122 and a second inner wall 123. The second outer wall 122 and the second inner wall 123 are both located at one end of the second slot insulating structure 121 away from the stator core module 2, and are integrally formed with the second slot insulating structure 121.

[0053] When the first insulating frame 11 is provided with inlet / outlet slots 1121 and bosses 1122, the second outer wall 122 is provided with buckles 1221, which can be used to gather and fix the three-phase windings. After the three-phase windings are wound, each phase winding is first fixed and distinguished by insulating sleeves of different colors, then the three-phase windings are wound together by insulating wire, and finally the insulating wire is tied to the buckles 1221 to fix the three-phase winding leads. Furthermore, the buckles 1221 are positioned on the radial center line of the second insulating frame 12, which is equivalent to the wire binding positioning post in the traditional insulating frame, fixing the leads to the outer ring wall of the frame to prevent the rotor from scraping the stator leads when rotating at high speed.

[0054] The first insulating frame 11 may also be provided with a buckle, and the second insulating frame 12 may be provided with a boss and an inlet / outlet groove.

[0055] Reference Figure 6 and Figure 7 A stator core module 2 cooperates with the insulating frame module 1 of any of the above claims. The stator core module 2 is provided with a recess 21 adapted to the joint portion 13. The cooperation between the stator core module 2 and the insulating frame module 1 avoids damage to the first slot insulation structure 111 and the second slot insulation structure 121 during winding by the winding machine, thereby improving the winding speed during the motor manufacturing process.

[0056] In some alternative embodiments, when the joint 13 is a plate-like structure, the width of the joint 13 is smaller than the width of the first slot insulation structure 111, and / or the width of the joint 13 is also smaller than the width of the second slot insulation structure 121. The stator core module 2 includes an interconnected yoke 22 and a tooth 23. When the joint 13 is arranged in a cuboid shape, the recess 21 of the stator core module 2 is located at the tooth 23.

[0057] In some alternative embodiments, when the joint 13 extends along the outer contour of the first groove 1111 and / or the second groove 1211, the recess 21 of the stator core module 2 is located at the tooth 23 and the yoke 22.

[0058] A stator includes a plurality of stator core modules 2 continuously distributed along the circumferential direction and a plurality of insulating frame modules 1 that cooperate with the plurality of stator core modules 2 one by one, wherein the insulating frame module 1 is any of the insulating frame modules 1 mentioned above; and the stator core modules 2 are any of the stator core modules 2 mentioned above.

[0059] An electric motor includes a rotor and a stator as described above. The stator is disposed on the outer or inner circumference of the rotor, wherein the thickness of the rotor core module is greater than the thickness of the stator core module 2. The number of motor slots and rotor poles for which the insulating frame module 1 is applicable are not limited. When the number of stator slots changes, only the radial span of each insulating frame module 1 needs to be adjusted according to the number of motor slots, and its basic structure remains unchanged. The number of rotor poles does not affect the structure of the insulating frame module. However, since the magnetic flux density distribution characteristics of the stator teeth occur when the rotor poles use ferrite materials with low remanence, to ensure that the magnetic flux density of the narrowed stator teeth does not exceed the magnetic flux density value corresponding to the knee point of the core material, the insulating frame module 1 is only applicable to motors where the total stack height of the rotor core is higher than the total stack height of the stator core.
