[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0049] The following is for reference. Figures 1-6 The insulating frame 10 according to a first aspect embodiment of the present invention is described.

[0050] like Figures 1-3 As shown, according to the first aspect of the present invention, an insulating frame 10 has a receiving cavity 11 formed inside, the receiving cavity 11 is used to receive the winding coil 20, and a plurality of connecting holes 12 are formed on the insulating frame 10 that communicate with the receiving cavity 11. The connecting holes 12 connect the outside of the insulating frame 10 and the receiving cavity 11.

[0051] As will be understood by those skilled in the art, when the first component 100 is assembled onto the motor, it needs to be potted inside the motor. The potting material is an insulating and thermally conductive material. During the potting process, the potting material gradually fills the space between the insulating frame 10 and the iron core 30, and the potting material can enter the receiving cavity 11 through the connecting hole 12. After the potting is completed, the potting material forms a thermally conductive part 50 in the receiving cavity 11 and between the insulating frame 10 and the iron core 30. The thermally conductive part 50 in the insulating frame 10 and the connecting hole 12 can provide a barrier between the winding coil 20 and the iron core 30, so that the winding coil 20 and the iron core 30 are insulated.

[0052] During the operation of the motor, the heat generated by the winding coil 20 can be transferred to the heat-conducting part 50 in the receiving cavity 11 and the connecting hole 12, and then transferred outward through the heat-conducting part 50. It can be understood that the heat-conducting part 50 formed by potting has a large contact area with the winding coil 20, and the heat-conducting part 50 has a high thermal conductivity, thus improving the heat dissipation efficiency of the winding coil 20.

[0053] According to the insulating framework 10 of the first aspect of the present application, by arranging the plurality of communication holes 12, in the process of pouring the motor, the pouring material can enter the accommodating cavity 11 and contact the winding coil 20 through the communication hole 12, the heat conduction part 50 is formed in the accommodating cavity 11 and between the insulating framework 10 and the iron core 30, in the process of the motor working, the heat generated by the winding coil 20 can be transmitted to the outside through the heat conduction part 50, so that the heat dissipation efficiency of the winding coil 20 can be improved, and the reliability in the process of the motor working can be improved.

[0054] In some embodiments of the present application, as shown in Figure 3 , Figure 4 and Figure 6 , the insulating framework 10 is annular, the insulating framework 10 is provided with a mounting portion 13 along the axis of the insulating framework 10, and the mounting portion 13 is provided with a through hole in the axial direction. Among them, the accommodating cavity 11 and the winding coil 20 are both annular extending through the through hole, in the process of assembling, the insulating framework 10 is sleeved on the iron core 30, in the process of the motor working, the first assembly 100 and the second assembly are circumferentially magnetically matched. In the process of product design, the size of the through hole can be adjusted to meet the needs of more product design.

[0055] In some embodiments of the present application, as shown in Figure 3 , Figure 4 and Figure 6 , the insulating framework 10 is formed with a plurality of communication holes 12 on at least one end surface in the axial direction. That is, the insulating framework 10 can be formed with a plurality of communication holes 12 on one end surface in the axial direction, and the insulating framework 10 can also be formed with a plurality of communication holes 12 on two end surfaces in the axial direction. It can be understood that the end surface size of the insulating framework 10 in the axial direction is large, and the communication hole 12 is arranged on the end surface of the insulating framework 10 in the axial direction, which can increase the contact area of the pouring material and the winding coil 20, and ensure the heat dissipation efficiency of the winding coil 20.

[0056] In some embodiments of the present application, as shown in Figure 4 and Figure 6 , the communication hole 12 located on the end surface of the insulating framework 10 in the axial direction includes a plurality of first communication holes 121, and the plurality of first communication holes 121 are arranged at intervals in the circumferential direction and / or radial direction of the insulating framework 10. That is, the plurality of first communication holes 121 can be arranged at intervals in the circumferential direction of the insulating framework 10, or the first communication holes 121 can be arranged at intervals in the radial direction of the insulating framework 10, or the first communication holes 121 can be arranged at intervals in the circumferential direction and the radial direction of the insulating framework 10. In the process of product design, the arrangement mode of the plurality of first communication holes 121 can be adjusted to meet the needs of more product design.

[0057] In some embodiments of the present application, as shown inFigure 3 and Figure 4 As shown in Figs. 1 and 2, the first communication holes 121 extend along the radial direction of the insulation framework 10, and a plurality of the first communication holes 121 are arranged along the circumferential direction of the insulation framework 10. In this way, the first communication holes 121 are uniformly distributed on the insulation framework 10, and the uniformity of heat dissipation of the winding coil 20 can be improved.

[0058] In some embodiments of the present application, as shown in Figs. 1 and 2, Figure 3 and Figure 4 As shown in Figs. 1 and 2, the width of the first communication hole 121 gradually increases in the radial outward direction of the insulation framework 10. It can be understood that the diameter of the annular winding coil 20 also gradually increases in the radial outward direction of the insulation framework 10, and the requirement for heat dissipation of the winding coil 20 also increases. By increasing the width of the first communication hole 121 in the radial outward direction of the insulation framework 10, the winding coil 20 with a larger diameter can be in contact with the heat-conducting part 50 with a larger area, thereby meeting the heat dissipation needs of the coils in different areas and further improving the uniformity of heat dissipation of the winding coil 20.

[0059] In some embodiments of the present application, as shown in Figs. 1 and 2, Figure 3 and Figure 4 As shown in Figs. 1 and 2, the first communication hole 121 is a fan-shaped hole. In this way, the size of the support structure between two first communication holes 121 is more uniformly distributed in the radial direction of the insulation framework 10, which can make the strength distribution of the insulation framework 10 more uniform, and it is easier to meet the design needs of the strength of each part of the insulation framework 10 in the product design process, thereby reducing the design difficulty, and the fan-shaped hole can improve the coverage of the first communication hole 121, thereby further improving the heat dissipation efficiency of the winding coil 20.

[0060] In some embodiments of the present application, the central angle of the two straight lines of the first communication hole 121 in the circumferential direction of the insulation framework 10 is 3°-15°. For example, the central angle of the two straight lines of the first communication hole 121 in the circumferential direction of the insulation framework 10 can be 3°, 4°, 5°, 6°, 8°, 12° or 15°, thereby meeting the use needs of the heat dissipation efficiency of the winding coil 20 and the support strength of the insulation framework 10, and in the product design process, the central angle of the two straight lines of the first communication hole 121 in the circumferential direction of the insulation framework 10 can be adjusted to meet more product design needs.

[0061] In some embodiments of the present application, the first communication hole 121 is a rectangular hole. In the product design process, the shape of the first communication hole 121 can be selected according to the design needs to meet the product design needs.

[0062] In some embodiments of the utility model, the number of the through holes 12 on the same end surface of the insulation framework 10 in the axial direction is 8-72. For example, the number of the through holes 12 on the same end surface of the insulation framework 10 in the axial direction can be 8, 12, 24, 36, 48, 56, 64 or 72, so that the heat dissipation efficiency of the winding coil 20 and the support strength of the insulation framework 10 can meet the use needs, and in the process of product design, the number of the through holes 12 on the same end surface of the insulation framework 10 in the axial direction can be adjusted, thereby meeting more product design needs.

[0063] In some embodiments of the utility model, as shown in Figure 3 , the plurality of through holes 12 include second through holes 122, and the second through holes 122 are arranged on the side wall of the circumferential edge of the insulation framework 10 and are perpendicular to the end surface. In this way, in the process of pouring, the pouring material can enter the accommodating cavity 11 from the second through holes 122 on the side wall of the circumferential edge of the insulation framework 10, so that after pouring is completed, the contact area of the winding coil 20 and the heat conduction part 50 can be improved, the heat conduction part 50 can dissipate heat to the winding coil 20 in the radial direction of the winding coil 20, thereby further improving the heat dissipation efficiency of the winding coil 20.

[0064] In some embodiments of the utility model, as shown in Figure 3 , the number of the second through holes 122 is multiple, for example, the second through holes 122 can be two, three, ten, thirty or seventy-two, and the plurality of second through holes 122 are arranged at intervals along the circumference of the insulation framework 10. In this way, the heat conduction part 50 in the plurality of second through holes 122 can dissipate heat to the winding coil 20 from multiple different positions of the winding coil 20, thereby further improving the heat dissipation efficiency and uniformity of the winding coil 20.

[0065] In some embodiments of the utility model, the second through holes 122 extend into a ring shape around the axis of the insulation framework 10. That is, the second through holes 122 are formed as open holes on the side wall of the circumferential edge of the insulation framework 10, so that in the process of pouring, the pouring material enters the accommodating cavity 11 from the second through holes 122, and the pouring material can wrap the winding coil 20 in the circumferential direction of the winding coil 20, thereby further improving the heat dissipation efficiency and uniformity of the winding coil 20.

[0066] In some embodiments of the utility model, as shown in Figure 2 , Figure 3 and Figure 5As shown in the drawings, the insulating framework 10 comprises a first framework 14 and a second framework 15 which are butted in the axial direction of the insulating framework 10 and cooperatively define the accommodating cavity 11. In the process of assembly, the winding coil 20 is first placed in the first framework 14, and then the first framework 14 and the second framework 15 are butted in the axial direction of the insulating framework 10, thereby realizing the assembly of the winding coil 20 in the insulating framework 10 and reducing the operation difficulty in the assembly process.

[0067] In some embodiments of the present application, the first framework 14 and the second framework 15 are connected through clamping. The clamping operation is convenient, can further reduce the assembly difficulty, and has high strength, so that the connection strength of the first framework 14 and the second framework 15 can meet the design requirements, and the product design difficulty can be reduced.

[0068] In some embodiments of the present application, as shown in Figure 3 and Figure 5 , the outer side of the first framework 14 is provided with a plurality of first clamping hooks 141, for example, the first clamping hooks 141 can be two, three, ten, thirty or seventy-two, and the plurality of first clamping hooks 141 are arranged at intervals along the circumference of the first framework 14, and the first framework 14 is clamped with the second framework 15 through the plurality of first clamping hooks 141. Thus, after the assembly of the first framework 14 and the second framework 15 is completed, a second communication hole 122 can be formed between the two adjacent first clamping hooks 141, and in the process of product design, the number, size or distribution area of the first clamping hooks 141 can be adjusted to meet more product design requirements.

[0069] In some embodiments of the present application, as shown in Figure 3 and Figure 5 , the outer side of the first framework 14 is provided with a plurality of first clamping hooks 141, for example, the first clamping hooks 141 can be two, three, ten, thirty or seventy-two, and the plurality of first clamping hooks 141 are arranged at intervals along the circumference of the first framework 14, and the first framework 14 is clamped with the second framework 15 through the plurality of first clamping hooks 141. Thus, after the assembly of the first framework 14 and the second framework 15 is completed, a second communication hole 122 can be formed between the two adjacent first clamping hooks 141, and in the process of product design, the number, size or distribution area of the first clamping hooks 141 can be adjusted to meet more product design requirements.

[0070] Thus, the clamping of the first skeleton 14 and the second skeleton 15 can be realized, and after the first skeleton 14 and the second skeleton 15 are assembled, the second communication hole 122 can be formed between the two groups of the first clamping hooks 141 and the second clamping hooks 151, and the length of the first clamping hooks 141 and the second clamping hooks 151 is not too long. It can be understood that when the clamping hook is long, the torque of the clamping hook is large, and the clamping hook is easy to break. Thus, the probability of damage of the first clamping hooks 141 and the second clamping hooks 151 during assembly is low, the yield can be improved, and the first clamping hooks 141 and the second clamping hooks 151 can limit the winding coil 20 during assembly, and the winding coil 20 is not easy to separate during assembly, so that the assembly difficulty can be further reduced.

[0071] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 The first skeleton 14 includes a first skeleton body 143 and a first flange 142, the first skeleton body 143 extends in the circumferential direction of the insulation skeleton 10 to be annular, and the first flange 142 is connected to the radially inner side edge of the first skeleton body 143 and extends in the axial direction of the insulation skeleton 10 to the second skeleton 15.

[0072] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 The second skeleton 15 includes a second skeleton body 153 and a second flange 152, the second skeleton body 153 extends in the circumferential direction of the insulation skeleton 10 to be annular, and the second flange 152 is connected to the radially inner side edge of the second skeleton body 153 and extends in the axial direction of the insulation skeleton 10 to the first skeleton 14.

[0073] During the assembly of the first skeleton 14 and the second skeleton 15, the first flange 142 is inserted into the inner side of the second flange 152 on the inner side, and the first clamping hook 141 and the second clamping hook 151 are clamped on the outer side, so that the assembly process is relatively simple.

[0074] The second flange 152, the first skeleton body 143, the second skeleton body 153, the first clamping hook 141 and the second clamping hook 151 can define a ring-shaped accommodating cavity 11, and the inner side of the first flange 142 is formed as a through hole of the mounting portion 13. In the process of product design, the size of the first skeleton body 143, the second skeleton body 153, the first flange 142 and the second flange 152 can be adjusted, and the number, size and distribution range of the first clamping hook 141 and the second clamping hook 151 can be adjusted, so as to meet more product design needs.

[0075] Reference will now be made to Figures 1-6 The motor according to the second aspect of the present application is described.

[0076] The motor according to the second aspect of the present application is described. Figure 1 and Figure 2 The motor according to the second aspect of the present application is described.

[0077] Specifically, the first assembly 100 includes the insulation skeleton 10, the winding coil 20 and the iron core 30 according to the first aspect of the present application. The winding coil 20 is arranged in the accommodating cavity 11, the iron core 30 is formed with the mounting cavity 31, the insulation skeleton 10 is arranged in the mounting cavity 31, and the second assembly moves relative to the first assembly 100 along the axial direction of the motor.

[0078] That is, the motor is a linear motor, one of the first assembly 100 and the second assembly is a stator assembly, and the other is a rotor assembly. In the working process of the motor, the winding coil 20 generates a magnetic field, and under the action of the magnetic field of the winding coil 20, the second assembly moves relative to the first assembly 100 along the axial direction of the motor, so that the external driving of the motor can be realized.

[0079] In the process of potting the first assembly 100 in the motor, the potting material can enter the accommodating cavity 11 from the communication hole 12 on the insulation skeleton 10. After the potting is completed, the potting material forms the heat conduction portion 50 in the accommodating cavity 11 and the mounting cavity 31 of the insulation skeleton 10. In the working process of the motor, the heat conduction portion 50 in the accommodating cavity 11 and the communication hole 12 can dissipate heat for the winding coil 20, so that the heat dissipation efficiency for the winding coil 20 can be improved, and the heat dissipation efficiency of the first assembly 100 can be improved.

[0082] In the first assembly 100, the motor wires are arranged in the wire passing grooves 161 of the plurality of insulation frames 10 respectively.

[0083] In the process of operation of the linear motor, vibration is inevitably generated, and the motor wires knock the insulation frame 10. It can be understood that the contact area between the wire passing baffle 16 and the motor wires is large, and the inner wall of the wire passing groove 161 is relatively smooth. Therefore, by arranging the motor wires in the wire passing groove 161, the probability that the insulation frame 10 damages the protective layer outside the motor wires and causes the insulation between the motor wires and the iron core 30 to fail can be reduced, thereby further improving the reliability of the motor in the process of operation.
