Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an amorphous alloy iron core and a motor. Background Technology

[0002] Traditional silicon steel sheets suffer from high losses, severely limiting the efficiency and power density of motors. Amorphous alloys, as emerging green soft magnetic materials, possess excellent characteristics such as high frequency, low loss, high strength, and high hardness. Compared to traditional silicon steel sheets, amorphous alloys have lower losses, especially at high frequencies. Therefore, amorphous alloys are highly suitable as stator cores for high-frequency, high-speed motors.

[0003] Amorphous alloy materials, due to their extremely thin thickness and good flexibility, possess excellent mechanical properties, but they also present many challenges in the fabrication of amorphous motors. Typically, the core of an amorphous motor is formed by bonding multiple layers of amorphous single-layer strips together to create a multi-layer composite strip, which is then stamped to form the core. The multiple layers of amorphous single-layer strips are simply bonded with adhesive, resulting in poor core strength that cannot meet the strength requirements during high-speed rotation. Therefore, the industry uses rivets on the amorphous single-layer strips, riveting and bonding the multiple layers together to improve the strength after lamination. However, the surface of the amorphous motor core is highly susceptible to delamination or peeling during assembly or use. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] The following is combined Figures 1-7 This invention describes the amorphous alloy iron core and motor.

[0028] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown in the embodiment of this utility model, the amorphous alloy core includes: a first end plate 10, a multilayer amorphous alloy plate body 20, and a second end plate 30. The multilayer amorphous alloy plate bodies 20 are stacked, with the first end plate 10 and the second end plate 30 disposed on both sides of the multilayer amorphous alloy plate bodies 20. Each layer of amorphous alloy plate body 20 is provided with a first through groove 21, and rivet fasteners 22 are respectively connected to opposite ends of the first through groove 21. Multiple rivet fasteners 22 of multiple amorphous alloy plate bodies 20 are stacked sequentially. The first end plate 10 is provided with a second through groove 11, which is opposite to the first through groove 21. The second end plate 30 is provided with a third through groove 31, which is opposite to the first through groove 21.

[0029] Specifically, after the multi-layer amorphous alloy plates 20 are stacked, multiple rivet fasteners 22 are stacked sequentially to form a rivet structure, thereby riveting the multi-layer amorphous alloy plates 20 into a whole. A first end plate 10 and a second end plate 30 are stacked on both sides of the multi-layer amorphous alloy plates 20, clamping the multi-layer amorphous alloy plates 20 and preventing delamination or peeling of the amorphous alloy plates 20 during assembly or use. In this embodiment, the two rivet fasteners 22 of each amorphous alloy plate 20 are symmetrically arranged, with a gap between the two rivet fasteners 22, which communicates with the first through groove 21. After the first end plate 10 and the second end plate 30 are stacked on both sides of the multi-layer amorphous alloy plates 20, the second through groove 11, the first through groove 21, the gap, and the third through groove 31 are connected to form a heat dissipation channel, thereby improving the heat dissipation capacity of the amorphous alloy core.

[0030] The amorphous alloy core provided in this embodiment of the invention avoids delamination or peeling during assembly or use by setting a first end plate and a second end plate on both sides of the multilayer amorphous alloy plate, thereby improving the performance of the amorphous alloy core and extending its service life.

[0031] Furthermore, such as Figure 2 As shown, in this embodiment of the present invention, the size of the second through groove 11 is larger than the size of the first through groove 21, and the size of the third through groove 31 is equal to the size of the first through groove 21. Specifically, in this embodiment, the length of the second through groove 11 is greater than the length of the first through groove 21, and the width of the second through groove 11 is greater than the width of the first through groove 21, so as to improve the heat dissipation effect. The third through groove 31 is a clearance groove, used to avoid the rivet fastener 22, that is, the lowest rivet fastener 22 is located in the third through groove 31.

[0032] like Figure 5As shown, in an embodiment of this utility model, each rivet 22 includes a first rivet part 221 and a second rivet part 222 connected together. The first rivet part 221 is connected to the groove wall of the first through groove 21, and the second rivet part 222 is arranged parallel to the amorphous alloy plate 20. The end of the second rivet part 222 is provided with an arc-shaped groove 2221. The arc-shaped grooves 2221 of the two second rivet parts 222 of each amorphous alloy plate 20 form heat dissipation holes, and the multiple heat dissipation holes of the multilayer amorphous alloy plate 20 are connected to form a heat dissipation channel.

[0033] Specifically, the first rivet portion 221 is inclined to the amorphous alloy plate 20, and the second rivet portion 222 is angled to the first rivet portion 221 and parallel to the amorphous alloy plate 20. In this embodiment, each rivet 22 has a bent portion, thereby forming an L-shaped structure. A first bent portion is formed between the first rivet portion 221 and the amorphous alloy plate 20, and a second bent portion is formed between the first rivet portion 221 and the second rivet portion 222. The two bent portion structures make it less likely for the horizontal plane to shift when the multilayer amorphous alloy plates 20 are stacked, thereby improving the strength of the multilayer amorphous alloy plates 20 after stacking.

[0034] In this embodiment, the second through slot 11, the first through slot 21, the heat dissipation channel, and the third through slot 31 are connected. To improve the heat dissipation effect of the amorphous alloy core, a cooling medium can be injected into the heat dissipation channel to exchange heat with the amorphous alloy plate 20 and remove the heat from the amorphous alloy plate 20. In this embodiment of the invention, the size of the second through slot 11 is designed to be larger than that of the first through slot 21, so that a portion of the surface of the amorphous alloy plate 20 can directly contact the cooling medium to further improve the heat dissipation effect.

[0035] Furthermore, such as Figure 5 As shown, a second through hole 23 is provided in the middle of the first through groove 21. The diameter of the second through hole 23 is larger than the width of the first through groove 21, so as to increase the space for the cooling medium and thus improve the cooling effect of the amorphous alloy plate 20.

[0036] Optionally, in an embodiment of the present invention, the length of the second rivet part 222 is 4mm-6mm, the width of the second rivet part 222 is 1mm-3mm, and the diameter of the heat dissipation through hole is 1mm-4mm.

[0037] like Figure 7 As shown in the embodiment of this utility model, the amorphous alloy core further includes a third end plate 40. The third end plate 40 is stacked on the surface of the second end plate 30 away from the amorphous alloy plate 20. The third end plate 40 is provided with a first through hole 41, which is connected to the heat dissipation channel. The diameter of the first through hole 41 is smaller than the diameter of the heat dissipation through hole.

[0038] Specifically, the third end plate 40 is provided with a first through hole 41 at a position opposite to the third through groove 31. The diameter of the first through hole 41 is smaller than the diameter of the heat dissipation hole on the amorphous alloy plate 20, so as to increase the resistance when the cooling medium flows, increase the heat exchange time between the cooling medium and the amorphous alloy plate 20, and thus enhance the heat dissipation effect of the amorphous alloy plate 20.

[0039] like Figure 3 , Figure 4 and Figure 6 As shown, the first end plate 10 has multiple second injection holes 12, the amorphous alloy plate 20 has multiple first injection holes 24, and the second end plate 30 has multiple third injection holes 32. The first injection holes 24, second injection holes 12, and third injection holes 32 are connected to form an injection channel. After injecting glue into the injection channel, the first end plate 10, the multilayer amorphous alloy plate 20, and the second end plate 30 can be bonded together as a whole.

[0040] In this embodiment, the multilayer amorphous alloy plates 20 are formed into an integral structure by riveting and bonding to improve the strength of the amorphous alloy core. Simultaneously, the first end plate 10 and the second end plate 30 are also bonded to the amorphous alloy plates 20.

[0041] Furthermore, the diameter of the first injection hole 24 is larger than the diameter of the second injection hole 12, and the diameter of the first injection hole 24 is equal to the diameter of the third injection hole 32.

[0042] Specifically, the diameter of the second injection hole 12 is smaller than that of the first injection hole 24 to prevent glue from flowing during the curing process of the amorphous alloy core. Designing the diameter of the third injection hole 32 to be equal to that of the first injection hole 24 increases the axial bonding force.

[0043] Furthermore, such as Figure 7 As shown, no glue injection hole is provided on the third end plate 40, so that the glue injection channel forms a blind hole structure, which prevents glue from flowing outside the amorphous alloy iron core, reducing the overall strength of the amorphous alloy iron core after glue injection, and at the same time increasing the pull-out force.

[0044] Optionally, in embodiments of this utility model, the first end plate 10, the second end plate 30, and the third end plate 40 are all magnetic end plates to improve the strength of the amorphous alloy core and avoid surface delamination or peeling.

[0045] This utility model embodiment also provides a motor, including a housing and an amorphous alloy core, the amorphous alloy core being disposed within the housing. In this embodiment, the amorphous alloy core is a stator core.

[0046] The motor provided in this embodiment of the utility model, by setting a first end plate and a second end plate on both sides of the multi-layer amorphous alloy plate, avoids delamination or peeling of the amorphous alloy core during assembly or use, improves the performance of the amorphous alloy core, and extends the service life of the amorphous alloy core.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
