Description

Technical Field

[0001] The utility model relates to the technical field of motor stators, in particular to a high-efficiency and energy-saving motor stator and rotor iron core. Background Art

[0002] The motor stator is an important part of the motor. The stator of an external rotor motor usually consists of three parts: the stator core, the stator winding and the motor shaft. The stator core is coaxially sleeved and installed on the motor shaft, and the insulated wire is wound on the stator core to form the stator winding.

[0003] The currently published patent: CN212935582U discloses a stator injection molded iron core and an outer rotor motor stator. The motor stator can effectively isolate the winding branches from the motor shaft by setting annular convex ribs, which can effectively prevent the enameled wires wound on the winding branches from contacting the motor shaft when the stator injection molded iron core is installed on the motor shaft, thereby ensuring the insulation effect and preventing the stator from short-circuiting and other faults, ensuring the safe, stable and reliable operation of the stator, and ensuring that the outer rotor motor can operate stably and reliably for a long time, which is suitable for promotion and application.

[0004] Based on the above search, it is found that the above patent has the following problems when used: although the motor stator can effectively prevent the enameled wire wrapped on the winding branch from contacting the motor shaft when the stator injection-molded iron core is installed on the motor shaft, thereby ensuring the insulation effect, the motor stator is an integrated structure. When faced with different circuit requirements, the installer cannot adjust the motor stator and rotor cores. Therefore, it can only adapt to motors of the same model, and cannot adapt to motors of multiple models. The scope of application has certain limitations. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a high-efficiency and energy-saving motor stator and rotor core, which can solve the problem that the motor stator is an integrated structure. When faced with different circuit requirements, the installer cannot adjust the motor stator and rotor core, so it can only adapt to motors of the same model, and cannot adapt to motors of multiple models, and the scope of application has certain limitations.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency and energy-saving motor stator and rotor core, comprising a stator and rotor body and a fixing device; a keyway is provided on the inner wall of the stator and rotor body, and a slide groove is evenly provided on the outer surface of the stator and rotor body, and a movable piece is slidably connected inside the slide groove; the fixing device comprises a fixed pressure ring, a threaded column and a nut, the fixed pressure ring is slidably sleeved on the surface of the stator and rotor body, the threaded column is threadedly connected inside the fixed pressure ring, the threaded columns are equidistantly distributed in a circle around the center of the fixed pressure ring, the nut is welded on the top of the threaded column, and the top of the nut is provided with a hexagonal prism groove for rotation.

[0007] Preferably, cylindrical grooves are evenly formed on the surface of the fixed pressure ring, and the surface of the nut is slidably connected to the inside of the cylindrical groove.

[0008] Preferably, a fixing groove is provided on the top of the movable sheet, and the surface of the fixing pressure ring is slidably connected to the inside of the fixing groove.

[0009] Preferably, threaded holes are evenly formed on the top of the stator and rotor bodies, and the threaded columns are threadedly connected inside the threaded holes.

[0010] Preferably, a positioning block is welded on the bottom of the movable sheet, and positioning slots are evenly formed on the bottom of the stator and rotor bodies, and the positioning block is slidably engaged in the interior of the positioning slots.

[0011] Preferably, a through hole is provided on the top of the movable sheet, and the through hole passes through the movable sheet.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the high-efficiency and energy-saving motor stator and rotor core is installed and fixed by a fixed pressure ring to multiple movable sheets, and by setting the movable sheet as a detachable structure, when facing different circuit requirements, the installer can adjust the motor stator and rotor core by replacing the movable sheet, so the motor stator and rotor core can be adapted to motors of different models, so it can be adapted to motors of various models, increasing the scope of application of the motor stator and rotor core. The high-efficiency and energy-saving motor stator and rotor core stores the nut through a cylindrical groove, so that the top of the nut and the top of the fixed pressure ring are at the same horizontal position to maintain the flatness of the top of the motor stator and rotor core, which can avoid the rotation of the nut during the rotation of the motor stator and rotor core and improve the stability of the use of the motor stator and rotor core. The high-efficiency and energy-saving motor stator and rotor core can reduce its own weight by opening a through hole on the surface of the movable sheet, thereby reducing the overall weight of the motor stator and rotor core, which can reduce the electric energy loss of the motor stator and rotor core rotation, and finally make the stator and rotor core have the advantages of high efficiency and energy saving.

[0021] A positioning block 12 is welded to the bottom of the movable piece 4, and positioning slots 13 are evenly formed at the bottom of the stator and rotor body 1, and the positioning block 12 is slidably engaged in the interior of the positioning slots 13;

[0022] When installing the motor stator and rotor core, the installer slides the movable sheet 4 downward into the interior of the slide slot 3, and the movable sheet 4 moves downward and drives the positioning card block 12 to slide downward into the interior of the positioning slot 13, thereby preventing the movable sheet 4 from moving laterally out of the slide slot 3. Then, the installer picks up the fixed pressure ring 6 and slides it downward to the interior of the card slot 5. Finally, the installer inserts the internal rotating nut 8 of the hexagonal prism groove 9 through a wrench and drives the threaded column 7 to rotate into the interior of the threaded hole 11. The installer rotates multiple nuts 8 in sequence and drives the threaded column 7 to rotate and enter the interior of the threaded hole 11 in sequence. The fixed pressure ring 6 can be fixedly installed on the top of the stator and rotor body 1 through multiple threaded columns 7. At this time, multiple movable sheets 4 can be installed and fixed through the fixed pressure ring 6. By setting the movable sheet 4 to a detachable structure, when facing different circuit requirements, the installer can adjust the stator and rotor core of the motor by replacing the movable sheet 4. Therefore, the stator and rotor core of the motor can be adapted to motors of different models, so it can be adapted to motors of multiple models, thereby increasing the scope of application of the stator and rotor core of the motor.

[0023] The surface of the fixed pressure ring 6 is evenly provided with cylindrical grooves 10, and the surface of the nut 8 is slidably connected with the inside of the cylindrical grooves 10;

[0024] During the process that the nut 8 rotates and drives the threaded column 7 to rotate into the threaded hole 11, the threaded column 7 rotates and gradually moves downward through the threaded connection with the threaded hole 11, and the threaded column 7 moves downward and drives the nut 8 to gradually move downward into the cylindrical groove 10. The nut 8 is stored by the cylindrical groove 10 so that the top of the nut 8 and the top of the fixed pressure ring 6 are at the same horizontal position to maintain the flatness of the top of the motor stator and rotor core, which can avoid the rotation of the nut 8 and the collision during the rotation of the motor stator and rotor core, thereby improving the stability of the motor stator and rotor core.

[0025] A through hole 14 is formed on the top of the movable sheet 4 , and the through hole 14 passes through the movable sheet 4 .

[0026] By opening a through hole 14 on the surface of the movable sheet 4 to reduce its own weight, and thus reduce the overall weight of the motor stator and rotor core, the electric energy loss of the motor stator and rotor core rotation can be reduced, and ultimately the stator and rotor core has the advantages of high efficiency and energy saving.

[0027] Working principle: For the stator and rotor core of the high-efficiency energy-saving motor, the installer slides the movable sheet 4 downward into the interior of the slide slot 3 and drives the positioning block 12 to slide downward into the interior of the positioning slot 13. The installer then picks up the fixed pressure ring 6 and slides it downward into the interior of the card slot 5. The installer finally inserts a wrench into the interior of the hexagonal prism groove 9 to rotate the nut 8 and drive the threaded column 7 to rotate into the interior of the threaded hole 11. The installer rotates multiple nuts 8 in sequence and drives the threaded column 7 to rotate and enter the interior of the threaded hole 11 in sequence. The fixed pressure ring 6 can be fixedly installed on the top of the stator and rotor body 1 through multiple threaded columns 7. At this time That is, multiple movable pieces 4 can be installed and fixed by fixing the pressure ring 6. By setting the movable piece 4 as a detachable structure, the installer can adjust the iron core of the motor stator and rotor by replacing the movable piece 4. The threaded column 7 rotates and gradually moves downward through the threaded connection with the threaded hole 11, driving the nut 8 to gradually move downward into the cylindrical groove 10. The nut 8 is stored through the cylindrical groove 10 so that the top of the nut 8 and the top of the fixed pressure ring 6 are at the same horizontal position, which can maintain the flatness of the top of the motor stator and rotor iron core, and can avoid the rotation of the nut 8 and the collision during the rotation of the motor stator and rotor iron core.
