Description

Technical Field

[0001] This utility model relates to a stator winding structure of a switched reluctance motor, belonging to the technical field of switched reluctance motors. Background Technology

[0002] Switched reluctance motors are a type of speed-regulating motor developed after DC motors and brushless DC motors. Countries such as the UK and the US started research on switched reluctance motors earlier and have achieved significant results. The power levels of these products range from several watts to hundreds of kilowatts, and they are widely used in household appliances, aviation, aerospace, electronics, machinery, and electric vehicles. Switched reluctance motors require the use of stator winding structures.

[0003] According to announcement number CN220570384U, a stator winding structure for a switched reluctance motor is disclosed, including a housing, a stator core disposed inside the housing, a slider fixedly mounted on the surface of the stator core, a high-temperature resistant insulating layer disposed on the inner wall of the stator core, a winding tooth fixedly mounted on one side of the stator core, and a fixing plate fixedly mounted on one end of the winding tooth. The stator core is fixed by screwing a fixing bolt into a threaded hole. A heat-conducting block, made of a material with good thermal conductivity such as silicone, is included to improve the thermal conductivity between the stator core and the ground. The thermal conductivity between stator windings is improved by the high-temperature resistant insulation layer, which protects the stator windings and reduces the frequency of short-circuit faults. The heat conductor, made of a high thermal conductivity resin material, further enhances the thermal conductivity between the stator windings, improving heat dissipation and motor performance. However, during the production process, workers need to place the stator core inside the casing and tighten the fixing bolts one by one to complete the installation. This results in low efficiency for workers during installation and reduces the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to provide a stator winding structure for a switched reluctance motor. This invention facilitates the assembly and disassembly of the device, thereby making it easier to maintain and improving its practicality, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A stator winding structure for a switched reluctance motor includes a housing, a housing, and a stator core. Multiple sliding grooves are arranged in a circular array on the rear side of the housing and the front side of the housing. A spring is fixedly mounted on the inner wall of the top of each sliding groove, and a slider is fixedly connected to the other end of each spring. A positioning rod is fixedly mounted on the bottom end of each slider. Multiple positioning grooves matching the positioning rods are arranged in a circular array on the outer wall of the stator core. Multiple stator windings are fixedly mounted in a circular array on the inner wall of the stator core.

[0007] Furthermore, the first housing has a ring array of locking studs that slide through it, and the second housing has a ring array of threaded grooves that match the locking studs.

[0008] Furthermore, each of the locking studs has a slot on its front side.

[0009] Furthermore, multiple sliding grooves are arranged in a ring array on both the front side of the first housing and the front side of the second housing, and multiple sliding blocks that match the sliding grooves are fixed in a ring array on the outer wall of the stator core.

[0010] Furthermore, each of the positioning rods has an inclined portion on the front side of the end closest to the stator core.

[0011] Furthermore, an arc-shaped structure is provided around the rear outer wall of the stator core.

[0012] Furthermore, the stator core has a ring array of several heat dissipation holes.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a positioning rod and a second slider. In use, the second slider is aligned with and inserted into the corresponding second groove. The stator core is then pushed until the second slider contacts the inner rear wall of the second groove. During this process, the stator core presses against the positioning rod, causing the positioning rod to push the first slider to compress the spring, thus moving the positioning rod into the first groove. Once the stator core is in the correct position, the spring pushes the first slider and the positioning rod to move and insert into the positioning groove, completing the assembly of the device. The addition of heat dissipation holes improves the device's heat dissipation. Locking studs allow for the disassembly and reassembly of the first and second housings, facilitating the replacement of the first slider and the positioning rod. This invention allows for convenient assembly and disassembly of the device, facilitating maintenance and improving its practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A stator winding structure for a switched reluctance motor includes a housing 1, a housing 2, and a stator core 3. Multiple sliding grooves 4 are arranged in a circular array on the rear side of the housing 1 and the front side of the housing 2. A spring 5 is fixedly mounted on the inner wall of the top of each sliding groove 4. A slider 6 is fixedly connected to the other end of each spring 5. A positioning rod 7 is fixedly mounted at the bottom end of each slider 6. Multiple positioning grooves 8, matching the positioning rods 7, are arranged in a circular array on the outer wall of the stator core 3. Multiple stator windings 9 are fixedly arranged in a circular array on the inner wall of the stator core 3.

[0025] Specifically, such as Figures 1-5 As shown, a plurality of locking studs 10 are slidably embedded in a ring array on the housing 1. A plurality of threaded grooves 11 matching the locking studs 10 are opened in a ring array on the front side of the housing 2. Each locking stud 10 has a slot on its front side. By using the locking studs 10, the housing 1 and the housing 2 can be disassembled and assembled, thereby facilitating the replacement of the slider 6 and the positioning rod 7.

[0026] Specifically, such as Figures 1-5 As shown, multiple sliding grooves 12 are arranged in a ring array on the front side of both the housing 1 and the housing 2. Multiple sliding blocks 13 that match the sliding grooves 12 are fixedly arranged in a ring array on the outer wall of the stator core 3. By setting the sliding blocks 13 and the sliding grooves 12, the stator core 3 can be conveniently positioned and installed.

[0027] Specifically, such as Figures 1-5 As shown, the positioning rod 7 has an inclined portion on the front side of the end near the stator core 3, and an arc-shaped structure is provided around the rear outer wall of the stator core 3. By setting the inclined portion and the arc-shaped structure, it is convenient for the stator core 3 to squeeze the positioning rod 7.

[0028] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that: the stator core 3 has a number of heat dissipation holes 14 arranged in a ring array. By setting the heat dissipation holes 14, the heat dissipation effect of the device can be improved.

[0029] The working principle of this utility model is as follows: In use, slide block 13 is aligned with the corresponding groove 12 and inserted. Then, the stator core 3 is pushed until slide block 13 contacts the inner rear wall of groove 12. During this process, the stator core 3 will press the positioning rod 7, which will push slide block 6 to press the spring 5, thereby moving the positioning rod 7 into groove 4. When the stator core 3 moves to the appropriate position, the spring 5 will push slide block 6 and positioning rod 7 to move and insert into the positioning groove 8, thus completing the assembly of the device. By setting heat dissipation holes 14, the heat dissipation effect of the device can be improved. When the device needs to be disassembled and repaired, the locking stud 10 is loosened and removed, so that housing 1 and housing 2 can be separated, and slide block 6 and positioning rod 7 can be taken out, at which point the device can be repaired.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
