[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 are only used to explain this utility model, and should not be construed as limiting this utility model.
[0049] The following is for reference. Figures 1-7The present invention describes a stator insulating frame 100 according to an embodiment of the present invention. The stator insulating frame 100 is mounted on the stator core 200 of a linear motor, and the winding coil 300 of the linear motor is disposed on the stator insulating frame 100. The stator insulating frame 100 is adapted to be stacked and assembled with the stator core 200. When the stator insulating frame 100 and the stator core 200 are assembled, the stator insulating frame 100 and the stator core 200 are stacked. The circumferential edge of the stator core 200 has a notch structure 201. It should be noted that the linear motor includes a stator assembly, which includes a stator core 200, a stator insulating frame 100, and a winding coil 300. The stator insulating frame 100 and the stator core 200 are stacked and assembled, and the winding coil 300 is disposed on the stator insulating frame 100. Specifically, each stator core 200 is provided with at least one stator insulation frame 100. This application uses the example of each stator core 200 having two stator insulation frames 100 for illustration. Along the axial direction of the stator core 200, the two stator insulation frames 100 are respectively provided on both sides of the stator core 200, and each stator insulation frame 100 is provided with a winding coil 300.
[0050] like Figures 1-7 As shown, the stator insulation frame 100 according to an embodiment of the present invention may include: a frame body 10 and an edge structure 18. The frame body 10 has a central hole 17 and has an inner edge and an outer edge. The edge structure 18 is disposed at least at one of the inner edge and the outer edge, and the edge structure 18 protrudes from the frame body 10 along the axial direction of the central hole 17, so that a mounting groove 14 for the winding coil 300 is formed on the stator insulation frame 100.
[0051] The frame body 10 can be a plate-like structure. A central hole 17 penetrates the frame body 10 along the axial direction of the stator insulation frame 100. Along the radial direction of the frame body 10, the inner wall of the central hole 17 forms the inner edge of the frame body 10, and the outer wall of the frame body 10 forms the outer edge. An edge structure 18 is provided at least one of the inner and outer edges; that is, an edge structure 18 is provided at either the inner or outer edge, or both the inner and outer edges. This application uses the example of providing edge structures 18 at both the inner and outer edges for illustration. The edge structure 18 installed at the inner edge can be arranged around the central hole 17 circumferentially. The edge structure 18 protrudes from at least one side of the frame body 10 along the axial direction of the central hole 17. When the stator insulation frame 100 is... Figure 1 When placed in the center direction, the axial direction of the center hole 17 is Figure 1In the Z direction. When the edge structure 18 protrudes from one side of the frame body 10 along the axial direction of the center hole 17, a mounting groove 14 can be formed on one side of the stator insulation frame 100. When the edge structure 18 protrudes from both sides of the frame body 10 along the axial direction of the center hole 17, mounting grooves 14 can be formed on both sides of the stator insulation frame 100, and the winding coil 300 is installed in the mounting groove 14.
[0052] In this application, by cooperating with the skeleton body 10 and the edge structure 18, a mounting groove 14 can be formed on at least one side of the stator insulation skeleton 100 along the axial direction of the stator insulation skeleton 100. This simplifies the structure of the stator insulation skeleton 100, facilitates the manufacturing of the stator insulation skeleton 100, and helps improve the production efficiency of the stator insulation skeleton 100. Furthermore, it facilitates the installation of the winding coil 300 on the stator insulation skeleton 100, improves the assembly efficiency of the stator insulation skeleton 100 and the winding coil 300, thereby helping to improve the production efficiency of the linear motor.
[0053] Therefore, by assembling the frame body 10 and the edge structure 18 together, the structure of the stator insulation frame 100 can be simplified, making it easier to install the winding coil 300 on the stator insulation frame 100, improving the assembly efficiency of the stator insulation frame 100 and the winding coil 300, thereby helping to improve the production efficiency of the linear motor.
[0054] In some specific embodiments of this utility model, such as Figure 3 As shown, the edge structure 18 may include a first edge 181, which is disposed at the central hole 17. The first edge 181 protrudes from the frame body 10 along the axial direction of the central hole 17, and a mounting groove 14 is formed between the first edge 181 and the frame body 10. The first edge 181 is located at the inner edge of the frame body 10; in other words, the first edge 181 is located on the inner wall of the central hole 17. At least one side of the first edge 181 protrudes from the frame body 10 along the axial direction of the central hole 17, thereby forming a mounting groove 14 on at least one side of the frame body 10. The mounting groove 14 is located outside the first edge 181 along the radial direction of the stator insulation frame 100 and outside the frame body 10 along the axial direction of the stator insulation frame 100. The fact that the first edge 181 protrudes from the frame body 10 along the axial direction of the central hole 17 facilitates the formation of the mounting groove 14 in the stator insulation frame 100.
[0055] In some specific embodiments of this utility model, such as Figure 3As shown, along the axial direction of the central hole 17, the first edge 181 protrudes from the first surface 12 of the skeleton body 10. Specifically, along the axial direction of the central hole 17, one side of the skeleton body 10 has the first surface 12, and the first edge 181 protrudes from the first surface 12 of the skeleton body 10, thereby forming a mounting groove 14 between the first edge 181 and the first surface 12 of the skeleton body 10.
[0056] In some specific embodiments of this utility model, along the axial direction of the central hole 17, the first edge 181 protrudes from the second surface 13 of the skeleton body 10, and the second surface 13 is disposed opposite to the first surface 12.
[0057] Along the axial direction of the central hole 17, one side of the skeleton body 10 has a first surface 12, and the other side of the skeleton body 10 has a second surface 13. The second surface 13 and the first surface 12 are arranged opposite each other along the axial direction of the central hole 17. Along the axial direction of the central hole 17, one end of the first edge 181 protrudes from the first surface 12 of the skeleton body 10, and the other end of the first edge 181 protrudes from the second surface 13 of the skeleton body 10. Thus, mounting grooves 14 can be formed between the first edge 181 and the first surface 12, and between the first edge 181 and the second surface 13. Consequently, mounting grooves 14 are formed on both sides of the stator insulation skeleton 100, so that the stator insulation skeleton 100 can simultaneously mount multi-layer winding coils 300.
[0058] In some specific embodiments of this utility model, such as Figure 3 As shown, the edge structure 18 may further include: a second edge 182, which is disposed on the outer edge of the skeleton body 10. The second edge 182 protrudes from the skeleton body 10 along the axial direction of the central hole 17. The first edge 181 and the second edge 182 form the sidewall of the mounting groove 14, and the skeleton body 10 forms the bottom wall of the mounting groove 14.
[0059] The second edge 182 is located at the outer edge of the skeleton body 10. Along the axial direction of the central hole 17, at least one end of the second edge 182 protrudes from the skeleton body 10. The first edge 181 and the second edge 182 protrude from the skeleton body 10 on the same side facing the skeleton body 10. The skeleton body 10, the first edge 181 and the second edge 182 together define the mounting groove 14, so that the first edge 181 and the second edge 182 form the sidewalls of the mounting groove 14, and the skeleton body 10 forms the bottom wall of the mounting groove 14.
[0060] In some specific embodiments of this utility model, such as Figure 3As shown, along the axial direction of the central hole 17, the second edge 182 protrudes from the first surface 12 of the skeleton body 10. Specifically, along the axial direction of the central hole 17, one side of the skeleton body 10 has the first surface 12, and the second edge 182 protrudes from the first surface 12 of the skeleton body 10, thereby forming a mounting groove 14 between the second edge 182 and the first surface 12 of the skeleton body 10.
[0061] In some specific embodiments of this utility model, along the axial direction of the central hole 17, the second edge 182 protrudes from the second surface 13 of the skeleton body 10.
[0062] Along the axial direction of the central hole 17, one side of the skeleton body 10 has a first surface 12, and the other side of the skeleton body 10 has a second surface 13. The second surface 13 and the first surface 12 are arranged opposite each other along the axial direction of the central hole 17. Along the axial direction of the central hole 17, one end of the second edge 182 protrudes from the first surface 12 of the skeleton body 10, and the other end of the second edge 182 protrudes from the second surface 13 of the skeleton body 10. Thus, a mounting groove 14 can be formed between the first edge 181, the second edge 182 and the first surface 12, or a mounting groove 14 can be formed between the first edge 181, the second edge 182 and the second surface 13. As a result, mounting grooves 14 are formed on both sides of the stator insulation skeleton 100, so that the stator insulation skeleton 100 can simultaneously mount multi-layer winding coils 300.
[0063] In some specific embodiments of this utility model, such as Figure 3 As shown, the stator insulation frame 100 has a wiring notch 11 on its circumferential edge. The wiring notch 11 penetrates the stator insulation frame 100 along the axial direction of the central hole 17 and is connected to the mounting groove 14.
[0064] The wiring notch 11 is located at the circumferential edge of the stator insulation frame 100, and the circumferential edge of the stator core 200 has a notch structure 201. After the stator insulation frame 100 is assembled onto the stator core 200, the wiring notch 11 corresponds to the notch structure 201 of the stator core 200 along the axial direction of the stator insulation frame 100. Along the axial direction of the stator insulation frame 100, the orthographic projection of the wiring notch 11 and the orthographic projection of the notch structure 201 overlap. As an example, along the axial direction of the stator insulation frame 100, the orthographic projection of the wiring notch 11 is located within the orthographic projection range of the notch structure 201. Alternatively, along the axial direction of the stator insulation frame 100, the orthographic projection of the wiring notch 11 and the orthographic projection of the notch structure 201 completely overlap.
[0065] Specifically, along the axial direction of the stator insulation frame 100, a stator insulation frame 100 can be respectively provided on both sides of the stator core 200, and each stator insulation frame 100 is provided with a winding coil 300. The circumferential edge of the stator insulation frame 100 has a wiring notch 11, and the circumferential edge of the stator core 200 has a notch structure 201. Along the axial direction of the stator insulation frame 100, the wiring notch 11 and the notch structure 201 are correspondingly provided. When the two winding coils 300 located on both sides of the stator core 200 are connected in series, the lead ends of the two winding coils 300 extend into the wiring notch 11 of one stator insulation frame 100, or the lead ends of the two winding coils 300 extend between the two wiring notches 11 of the two stator insulation frames 100. The lead ends of the winding coils 300 are located radially outside the stator core 200, and then the lead ends of the two winding coils 300 are connected, for example, by welding. By connecting two winding coils 300 in series at the wiring notch 11, the winding coils 300 are connected in series around the circumference of the stator insulation frame 100. This increases the wiring operation space, facilitates wiring between the winding coils 300, and makes welding connections between the winding coils 300 easier, thus improving the production efficiency of the linear motor. Furthermore, because the wiring notch 11 connects to the mounting slot 14, after the winding coils 300 are installed in the mounting slot 14, the lead ends of the winding coils 300 can easily extend into the wiring notch 11.
[0066] In some specific embodiments of this utility model, such as Figure 3 As shown, along the radial direction of the stator insulation frame 100, the frame body 10 is provided with a wiring groove 15 extending radially along the central hole 17, and the wiring groove 15 is connected to the wiring notch 11.
[0067] Among them, such as Figure 3 and Figure 4 As shown, a wiring groove 15 can be formed on the bottom wall of the mounting groove 14. The wiring groove 15 is connected to the wiring notch 11. The wiring groove 15 can be a strip structure, and one end of the wiring groove 15 is connected to the wiring notch 11. The winding coil 300 is assembled in the mounting groove 14, and the lead end of the winding coil 300 is assembled in the wiring groove 15. The lead end of the winding coil 300 extends into the wiring notch 11 along the wiring groove 15. The wiring groove 15 has a guiding and positioning function for the lead end of the winding coil 300, thereby facilitating the wiring of the lead end of the winding coil 300.
[0068] In some specific embodiments of this utility model, such as Figure 3 and Figure 4As shown, the wiring groove 15 is arranged radially along the stator insulation frame 100. The winding coil 300 is assembled in the mounting groove 14, and the lead end of the winding coil 300 is assembled in the wiring groove 15. By arranging the wiring groove 15 radially along the stator insulation frame 100, it is convenient for the lead end of the winding coil 300 to extend into the wiring notch 11 along the wiring groove 15, thereby making it easier to route the lead end of the winding coil 300.
[0069] In some specific embodiments of this utility model, a protruding structure 16 is provided on the side of the skeleton body 10 away from the wiring groove 15, and the protruding structure 16 is adapted to cooperate with the stator core 200.
[0070] Among them, such as Figure 5 As shown, along the axial direction of the stator insulation frame 100, a protruding structure 16 is provided on the side of the frame body 10 facing away from the wiring groove 15. In other words, a protruding structure 16 is provided on the side of the frame body 10 facing the stator core 200, and the boss structure 16 is suitable for assembly into the mounting groove of the stator core 200. Further, along the axial direction of the stator insulation frame 100, an mounting groove is formed on the end face of the stator core 200 facing the stator insulation frame 100. After the stator insulation frame 100 is installed on the stator core 200, a boss structure 16 is formed on the side of the frame body 10 facing the stator core 200. After the stator insulation frame 100 is installed on the stator core 200, the boss structure 16 is assembled into the assembly slot of the stator core 200. The boss structure 16 can be embedded in the assembly slot of the stator core 200. Through the limiting cooperation between the boss structure 16 and the inner wall of the assembly slot, the stator core 200 and the stator insulation frame 100 are more robust and reliable. Furthermore, the boss structure 16 embedded in the assembly slot of the stator core 200 helps to improve space utilization and reduce the volume occupied by parts, thus reducing the volume of the stator insulation frame 100.
[0071] In some specific embodiments of this utility model, such as Figure 3 and Figure 5 As shown, along the axial direction of the central hole 17, a portion of the skeleton body 10 protrudes to one side to form a wiring groove 15 and a raised structure 16. The boss structure 16 and the wiring groove 15 can be located at the same place, thereby reducing the processing difficulty.
[0072] Along the axial direction of the stator insulation frame 100, the boss structure 16 and the wiring groove 15 are correspondingly arranged. A part of the frame body 10 protrudes to one side, thus forming a boss structure 16 on one side of the frame body 10 and a wiring groove 15 on the other side, achieving the desired arrangement of the boss structure 16 and the wiring groove 15. The boss structure 16 is embedded in the assembly slot of the stator core 200, which greatly improves the space utilization rate and further reduces the volume occupied by parts, thereby reducing the volume of the stator insulation frame 100.
[0073] In some specific embodiments of this utility model, the stator insulating frame 100 may further include: an insulating structure 20, the insulating structure 20 being disposed on the outer edge of the frame body 10, the insulating structure 20 and the frame body 10 being integrally formed, and a wiring notch 11 being disposed on the insulating structure 20.
[0074] The insulating structure 20 and the frame body 10 can be made of the same material; for example, both the insulating structure 20 and the frame body 10 can be made of plastic. The insulating structure 20 can be glued to the frame body 10 or snapped onto the frame body 10. The insulating structure 20 defines a wiring notch 11 and can be assembled into the notch structure 201. After the stator insulating frame 100 is installed on the stator core 200, the insulating structure 20 is assembled into the notch structure 201. The insulating structures 20 of the stator insulating frames 100 located on both sides of the stator core 200 are all assembled into the notch structure 201, and the insulating structures 20 of the two stator insulating frames 100 located on both sides of the stator core 200 are arranged opposite each other, and the insulating structures 20 of the two stator insulating frames 100 located on both sides of the stator core 200 can abut against each other. The wiring notches 11 of the two insulating structures 20 are joined to form a wiring space 21. When the two winding coils 300 located on both sides of the stator core 200 are connected in series, the lead ends of the two winding coils 300 extend into the wiring space 21, and the wiring is performed within the wiring space 21. The insulation structure 20 provides insulation; located between the stator core 200 and the winding coils 300, the insulation structure 20 isolates the stator core 200 and the winding coils 300, reducing the risk of short circuit due to contact between the stator core 200 and the winding coils 300.
[0075] In some specific embodiments of this utility model, such as Figure 2 As shown, the insulation structure 20 is adapted to abut against the inner wall of the notch structure 201. When the stator insulation frame 100 is installed on the stator core 200, the abutment between the insulation structure 20 and the inner wall of the notch structure 201 reduces the risk of movement of the stator insulation frame 100 relative to the stator core 200, and improves the assembly stability of the stator insulation frame 100 and the stator core 200.
[0076] In some specific embodiments of this utility model, such as Figure 5 As shown, the insulation structure 20 and the frame body 10 are integrally formed, for example, by injection molding. Integrating the insulation structure 20 and the frame body 10 reduces the risk of separation between them, further reducing the risk of short circuits caused by contact between the stator core 200 and the winding coil 300. Furthermore, it reduces the number of molds required to produce the stator insulation frame 100, thereby lowering its production cost.
[0077] In some specific embodiments of this utility model, such as Figures 3-5 As shown, there are multiple wiring notches 11, arranged sequentially along the circumference of the stator insulation frame 100. There can also be multiple notch structures 201, with each wiring notch 11 corresponding to one of the notch structures 201. The wiring notches 11 can be two, three, four, five, six, etc., and are arranged at intervals along the circumference of the stator insulation frame 100. The wiring groove 15 is connected to one wiring notch 11. When connecting to a three-phase power supply, not only do the winding coils 300 inside the stator assembly need to be connected in series, but stator assemblies connected to the same phase power supply also need to be connected in series. Since the phases of the stator assemblies are different, by setting multiple wiring notches 11, the corresponding stator insulation frame 100 can be rotated, facilitating wiring, improving the versatility and utilization of the stator insulation frame 100, increasing production efficiency, saving costs, and contributing to the mass production of the stator insulation frame 100. It should be noted that because the wiring groove 15 is connected to one wiring notch 11, assembly and wiring errors can be effectively avoided, improving production efficiency.
[0078] In some specific embodiments of this utility model, such as Figures 3-5 As shown, multiple wiring notches 11 are evenly arranged along the circumference of the stator insulation frame 100. This application uses six wiring notches 11 as an example for illustration. The six wiring notches 11 are evenly arranged along the circumference of the stator insulation frame 100, with a 60° interval between adjacent wiring notches 11. Both the spacing angle between the lead ends of the winding coil 300 and the spacing angle between the lead ends and the outlet ends of the winding coil 300 are multiples of 60°. Therefore, by setting multiple wiring notches 11, the versatility and utilization rate of the stator insulation frame 100 are further improved, production efficiency can be further increased, costs can be further saved, and it is conducive to the mass production of the stator insulation frame 100.
[0079] It should be noted that there are multiple insulation structures 20, and each insulation structure 20 and each wiring notch 11 is set in a one-to-one correspondence.
[0080] It should be noted that the axial direction of the stator insulation frame 100 and the axial direction of the stator assembly are both... Figure 1 In the Z-direction, the stator core 200, stator insulation frame 100, and winding coil 300 of this application are all designed as independent components and then assembled during use. The stator insulation frame 100 surpasses existing stator insulation frames in many aspects, including layout space, production efficiency, processing difficulty, maintenance convenience, structural complexity, and consistency of parts.
[0081] In some specific embodiments of this utility model, such as Figure 1 and Figure 2As shown, along the radial direction of the stator insulation frame 100, the wiring notch 11 is adapted to correspond to the notch structure 201. The stator core 200 includes a core body 202 and multiple limiting portions 203. The multiple limiting portions 203 are disposed on the outer side wall of the core body 202 and surround the core body 202. Along the axial direction of the stator assembly, the core body 202 is located at the center of the limiting portions 203, forming groove structures on both sides of the core body 202 for mounting the stator insulation frame 100. A first sub-notch structure 2011 is formed on the circumferential edge of the core body 202, and a second sub-notch structure 2012 corresponding to the first sub-notch structure 2011 is formed on the limiting portion 203. The first sub-notch structure 2011 and the second sub-notch structure 2012 are connected, and the first sub-notch structure 2011 and the second sub-notch structure 2012 are constructed as the notch structure 201.
[0082] After the stator insulation frame 100 and stator core 200 are stacked and assembled, the wiring notch 11 and the second sub-notch structure 2012 are correspondingly arranged along the radial direction of the stator insulation frame 100. The orthographic projection of the wiring notch 11 and the orthographic projection of the second sub-notch structure 2012 overlap in the radial direction of the stator insulation frame 100, and the orthographic projection of the wiring notch 11 and the first sub-notch structure 2011 overlap in the axial direction of the stator insulation frame 100. By correspondingly arranging the wiring notch 11 and the notch structure 201 along the radial direction of the stator insulation frame 100, after the winding coil 300 is installed on the stator insulation frame 100, it is beneficial for the lead end of the winding coil 300 to extend into the wiring notch 11, and also beneficial for the lead end of the winding coil 300 to extend between the two wiring notches 11 of the two stator insulation frames 100.
[0083] In some specific embodiments of this utility model, the frame body 10 has a central hole 17 at its middle position. Along the axial direction of the stator insulation frame 100, the central hole 17 penetrates the frame body 10. The mounting groove 14 is an annular structure, surrounding the central hole 17 and fitting within it. The mounting groove 14 is used to nest the winding coil 300. After the stator insulation frame 100 is installed on the stator core 200, a portion of the stator core 200's structure is embedded in the central hole 17, thus making the overall structure of the stator core 200 and the stator insulation frame 100 compact, which helps to reduce the volume of the stator assembly.
[0084] In some specific embodiments of this utility model, such as Figure 3 As shown, a mounting step 19 is formed at the end of the first edge 181, and the mounting step 19 is used to mount the insulating element.
[0085] The first edge 181, at its end furthest from the frame body 10, has a mounting step 19. This mounting step 19 is used to mount an insulating component, which can be insulating paper or an insulating film, etc. The linear motor may include multiple stator cores 200, which are stacked sequentially. Adjacent stator cores 200 are separated by an insulating component. The insulating component is nested at the mounting step 19 of the first edge 181, resulting in a compact stator assembly structure and high material utilization.
[0086] In some specific embodiments of this utility model, such as Figure 1 As shown, the stator insulation frame 100 is suitable for assembly into the slot structure of the stator core 200. When the stator insulation frame 100 is assembled into the slot structure, the circumferential edge of the frame body 10 extends out of the slot structure.
[0087] In this embodiment, along the axial direction of the stator insulation frame 100, slot structures are formed on both sides of the stator core 200. The stator insulation frames 100 on both sides of the stator core 200 are assembled into the corresponding slot structures. When the stator insulation frame 100 is assembled into the slot structure, along the axial direction of the stator insulation frame 100, the circumferential edge of the frame body 10 extends out of the slot structure. It can also be understood that the circumferential edge of the frame body 10 protrudes out of the slot structure. The stator insulation frame 100 plays an insulating role between the winding coil 300 and the stator core 200, which can eliminate the need for the arrangement of insulating components in the above embodiment.
[0088] like Figure 1 As shown, the stator assembly according to an embodiment of the present invention includes: a stator core 200, a stator insulating frame 100, and a winding coil 300. The stator core 200 has mounting holes. The stator insulating frame 100 is the same as the one described in the above embodiment, with a central hole 17 corresponding to the mounting holes, and the stator insulating frame 100 is disposed on the stator core 200. The winding coil 300 is disposed on the stator insulating frame 100, and the winding coil 300 is located on the side of the stator insulating frame 100 away from the stator core 200. The stator insulating frame 100 and the stator core 200 are stacked and assembled. Along the axial direction of the stator assembly, the central hole 17 corresponds to the mounting holes. The stator insulating frame 100 is disposed within the slot structure of the stator core 200, and the winding coil 300 is assembled on the stator insulating frame 100 and located on the side of the stator insulating frame 100 away from the stator core 200. By assembling the frame body 10 and the edge structure 18 together, the structure of the stator insulation frame 100 can be simplified, making it easier to install the winding coil 300 on the stator insulation frame 100, improving the assembly efficiency of the stator insulation frame 100 and the winding coil 300, thereby helping to improve the production efficiency of the stator assembly and the linear motor.
