[0002] The stator core is a part of an electric motor or a generator. It is located inside the stator of the motor and is usually laminated by thin silicon steel sheets or soft magnetic materials. The slots on the stator core are used to place the stator coils, which are key components for generating electromagnetic fields. The iron core can provide physical support for the coils to ensure that the coils remain stable during the operation of the motor. The stator core can form a closed magnetic circuit together with the rotor core and the permanent magnets or electromagnets in the motor, and this magnetic circuit is a necessary condition for generating a magnetic field when the motor is working properly.

[0003] At present, some existing stator cores are not convenient for disassembly. If a motor fails, such as coil damage or replacement is needed, the inconveniently disassembled stator core will complicate the maintenance process and increase the maintenance time and cost.

All other specific embodiments obtained by those of ordinary skill in the art based on the specific embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figures 1-4 , a specific embodiment provided by the present utility model is as follows:

[0032] A stator core that is easy to disassemble includes a first core 1 and a second core 2. The first core 1 and the second core 2 are slidably connected to each other. The slidable arrangement of the first core 1 and the second core 2 facilitates the replacement of local cores or coils, and is convenient for operating the stator core. A first slider 4 is fixedly connected to one side of both the first core 1 and the second core 2. A first sliding groove 5 is formed on the side of both the first core 1 and the second core 2 away from the first slider 4. The first slider 4 and the first sliding groove 5 facilitate the sliding connection between the first core 1 and the second core 2. Align the first slider 4 of the first core 1 with the first sliding groove 5 of the second core 2, and the first core 1 and the second core 2 can be installed at intervals. The first slider 4 slides inside the first sliding groove 5, and the first slider 4 sliding inside the first sliding groove 5 facilitates the connection between the first core 1 and the second core 2. Fixed sleeves 6 are slidably connected to the front, rear, left, and right sides of the outer walls of the first core 1 and the second core 2. The fixed sleeves 6 facilitate the fixation of the assembled cores to prevent their positions from shifting after sliding relative to each other. Connecting plates 7 are fixedly connected to the upper and lower ends of the outer walls of the fixed sleeves 6. Installation holes 8 are formed on both sides of the connecting plates 7. The installation holes 8 facilitate the connection of the connecting plates 7 on both sides, thereby fixing the fixed sleeves 6 on both sides. Bolts 12 are movably connected inside the connecting plates 7. The bolts 12 facilitate the connection of the fixed sleeves 6 on both sides;

[0033] A plurality of heat dissipation holes 11 are formed inside both the first core 1 and the second core 2. The heat dissipation holes 11 facilitate enhancing the overall heat dissipation function and prevent the stator core from affecting the use effect due to excessive temperature during operation. A second sliding groove 10 is formed on the side of the outer wall of the first core 1 close to the first slider 4. A second slider 9 is fixedly connected to one side of the inner wall of the fixed sleeve 6. The second slider 9 and the second sliding groove 10 facilitate the sliding installation of the fixed sleeve 6 on both sides of the outer wall of the core, thereby completing the installation of the fixed sleeve 6. The second slider 9 slides and is limited inside the second sliding groove 10. The second slider 9 sliding inside the second sliding groove 10 facilitates the connection between the fixed sleeve 6 and the first core 1;

[0034] On both sides of the outer walls of the first iron core 1 and the second iron core 2, iron core teeth 3 are fixedly connected. The arrangement of the iron core teeth 3 facilitates the placement of the stator coil. Thus, when the coil is energized, the iron core teeth 3 can help form a concentrated magnetic field.

[0035] Working principle: During use, connect the first iron core 1 and the second iron core 2, make the first slider 4 cooperate with the first chute 5, and enable the first slider 4 to slide inside it, so that the adjacent first iron core 1 and the second iron core 2 can slide and cooperate with each other and be connected. Install the first iron core 1 and the second iron core 2 at intervals, and the positions of the second chutes 10 can be made opposite. Slide the fixing sleeve 6 to both sides of the outer wall of the iron core, make the second slider 9 cooperate with the second chute 10 and slide, so as to install the fixing sleeves 6 on both sides to the outer wall of the iron core. Align the installation holes 8 on both sides, and make the bolt 12 pass through the connecting plate 7 to connect the fixing sleeves 6 on both sides, which can prevent the first iron core 1 and the second iron core 2 from sliding relative to each other. Wind the coil around the iron core teeth 3 to start working. When it is necessary to replace the iron core or the coil, the fixing sleeve 6 can be removed and the iron core can be removed separately. A plurality of heat dissipation holes 11 are provided inside both the first iron core 1 and the second iron core 2, enhancing the overall heat dissipation function and preventing the stator iron core from affecting the use effect due to excessive temperature during operation.
