Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a precision axial flux stator assembly. Background Technology

[0002] An axial magnetic field motor includes a stator and a rotor. The stator generates a magnetic field through windings, and the rotor rotates under the influence of this magnetic field. The stator includes a stator core and a stator plate. The stator core is made of silicon steel strip wound to form axial magnetic flux.

[0003] A search revealed a patent with application number CN201820419896.0, which discloses a high-performance motor stator. This stator includes a stator core and winding coils. The stator core comprises a stator yoke and several spaced stator teeth extending inward from the yoke. Winding slots are formed between adjacent stator teeth. The winding coils are embedded in the winding slots and wound around the stator teeth. The stator yoke is composed of several stator yoke units, with adjacent yoke units connected as a single unit via dovetail grooves and dovetail blocks. The tooth tips of the stator teeth are respectively provided with V-shaped grooves or semi-circular grooves, alternating between the two. The inner wall of the stator yoke adjacent to the stator teeth has a straight structure.

[0004] However, in actual use, the above-mentioned patent has the following drawbacks: it is not convenient to disassemble the stator teeth, the disassembly steps are cumbersome, and it causes great trouble to users. Therefore, we propose a precision axial flux stator assembly. Utility Model Content

[0005] The purpose of this invention is to provide a precision axial flux stator assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision axial flux stator assembly, comprising a stator core, wherein a plurality of detachable stator teeth are equidistantly arranged around the inner wall of the stator core, and the surfaces of the stator teeth are in movable contact with the inner wall of the stator core.

[0007] Furthermore, two rectangular slots are provided on the side of the stator tooth near the inner wall of the stator core, and rectangular insert blocks are movably engaged inside the rectangular slots.

[0008] Furthermore, the side of the rectangular insert block closest to the inner wall of the stator core is fixedly connected to the inner wall of the stator core, and the side of the rectangular insert block away from the inner wall of the stator core passes through the rectangular socket and extends to the outside of the rectangular socket. The sides of the two rectangular insert blocks that are close to each other are provided with slots.

[0009] Furthermore, a locking block is movably engaged inside the slot, two sliding rods are fixedly connected to the inner wall of the stator teeth, and movable plates are movably connected to the sides of the two rectangular inserts that are close to each other.

[0010] Furthermore, the movable plate is slidably sleeved on the slide rod, and the movable plate is fixedly connected to the locking block. Two threaded grooves are symmetrically opened on the inner wall of the stator teeth.

[0011] Furthermore, a movable groove is provided on the outer wall of the stator tooth corresponding to the position of the thread groove. The movable groove and the thread groove are interconnected. Threaded rods are rotatably connected to the two movable plates on the side away from each other and at the position corresponding to the thread groove.

[0012] Furthermore, the end of the threaded rod away from the movable plate passes through the threaded groove and the movable groove in sequence and extends into the interior of the movable groove, where a handle is fixedly connected, and the threaded rod and the threaded groove are threadedly connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention enables convenient disassembly of stator teeth. During disassembly, simply turn the handle counterclockwise, causing the threaded rod to rotate. This causes the threaded rod to move closer to the movable plate within the threaded groove, which in turn moves the movable plate and the locking block away from the groove. This disengages the locking block from the groove, and then pulls the stator teeth away from the inner wall of the stator core, causing the rectangular insert to disengage from the rectangular socket. Thus, the stator teeth can be removed. These steps allow for convenient disassembly of the stator teeth, simplifying the operation, saving time and effort, and providing great convenience to the user. Attached Figure Description

[0022] Please see Figure 1-4 A precision axial flux stator assembly includes a stator core 1, with multiple detachable stator teeth 2 arranged at equal intervals around the inner wall of the stator core 1, and the surfaces of the stator teeth 2 making movable contact with the inner wall of the stator core 1.

[0023] Specifically, two rectangular slots 3 are provided on the side of the stator tooth 2 near the inner wall of the stator core 1, and rectangular insert blocks 4 are movably engaged inside the rectangular slots 3. Through the cooperation of the rectangular insert blocks 4 and the rectangular slots 3, the stator tooth 2 can be initially positioned.

[0024] In practice, the side of the rectangular insert 4 closest to the inner wall of the stator core 1 is fixedly connected to the inner wall of the stator core 1, and the side of the rectangular insert 4 away from the inner wall of the stator core 1 passes through the rectangular socket 3 and extends to the outside of the rectangular socket 3. The two rectangular inserts 4 have a slot 5 on the side that is close to each other, and the slot 5 is rectangular.

[0025] Specifically, the slot 5 has a movable locking block 6 inside, two sliding rods 7 are fixedly connected to the inner wall of the stator tooth 2, and movable plates 8 are movably connected to the side of the two rectangular inserts 4 that are close to each other.

[0026] In practice, the movable plate 8 is slidably sleeved on the slide rod 7, and the movable plate 8 is fixedly connected to the locking block 6. Two threaded grooves 10 are symmetrically opened on the inner wall of the stator tooth 2.

[0027] Specifically, a movable groove 11 is provided on the outer wall of the stator tooth 2 at the position corresponding to the thread groove 10. The movable groove 11 and the thread groove 10 are interconnected. Threaded rods 12 are rotatably connected to the two movable plates 8 on the side away from each other and at the position corresponding to the thread groove 10.

[0028] In practice, the end of the threaded rod 12 away from the movable plate 8 passes through the threaded groove 10 and the movable groove 11 in sequence and extends into the interior of the movable groove 11 and is fixedly connected to the handle 13. The threaded rod 12 and the threaded groove 10 are threadedly connected.

[0029] In practical applications: When disassembling stator tooth 2, simply turn handle 13 counterclockwise, which will cause threaded rod 12 to rotate. This will cause threaded rod 12 to move closer to movable plate 8 within threaded groove 10, thereby causing movable plate 8 and locking block 6 to move away from locking groove 5. This will cause locking block 6 to disengage from locking groove 5. Then, pull stator tooth 2 away from the inner wall of stator core 1, thereby causing rectangular insert 4 to disengage from rectangular insert 3. Thus, stator tooth 2 can be removed. Through the above steps, stator tooth 2 can be easily disassembled. The operation is simple, time-saving, and labor-saving, providing great convenience to users.
