Description

Technical Field

[0001] The present invention relates to the technical field of motor devices, and specifically to an efficient motor rotor and stator structure. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. Motors are widely used in industries, household appliances, transportation, etc. When the motor coil is energized, a magnetic field is generated, which interacts with a permanent magnet or another set of coils to drive the rotor to rotate and output mechanical power. The main function of the motor is to provide power for various mechanical equipment, such as fans, water pumps, electric vehicles, etc., to drive the equipment to operate; The motor stator is one of the important parts inside the motor. When the motor stator works for a long time, its iron core may be damaged locally. It is necessary to remove the entire iron core and disassemble it for repair, and then reinstall the repaired stator into the interior of the stator. The steps are cumbersome and not conducive to emergency repair of the motor. For this reason, we have proposed an efficient motor rotor and stator structure. Summary of the Invention

[0003] The purpose of the present invention is to provide an efficient motor rotor and stator structure to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is an efficient motor rotor and stator structure, including a stator mechanism, which is used to complete the assembly of the motor stator and facilitate the maintenance and repair of the stator mechanism by the staff; A rotor mechanism, which is installed at the center of the stator mechanism. After the rotor mechanism is energized, electromagnetic induction will occur with the stator mechanism; A protection mechanism, which is installed outside the stator mechanism and is used to protect the stator mechanism; Among them, the rotor mechanism and the stator mechanism cause the rotor mechanism to rotate at the center of the stator mechanism through electromagnetic induction, enabling the rotor mechanism to output power outward.

[0005] Further, the stator mechanism includes a quick-disassembly component, which is used to quickly replace damaged parts; An auxiliary component, which is installed inside the quick-disassembly component and is used to fix several parts of the quick-disassembly component together; Among them, the auxiliary component can introduce air into the interior of the quick-disassembly component to assist in cooling the quick-disassembly component.

[0006] Further, the rotor mechanism includes a rotor component, which is installed at the center of the quick-disassembly component. The rotor component will rotate through electromagnetic induction and output power outward; The limiting component is installed outside the rotor component and is used to limit the rotor component. Among them, the limiting component can restrict the movement of the rotor component, enabling the limiting component to rotate at the center of the quick-release component.

[0007] Furthermore, the protection mechanism includes a protection component installed outside the quick-release component, and the protection component is used to protect several parts of the stator mechanism and the rotor mechanism. The positioning component is installed inside the protection component and is used to support the quick-release component. Among them, the setting of the positioning component enables the protection component to be quickly installed outside the quick-release component.

[0008] Furthermore, the quick-release component includes two component cover plates. The two component cover plates are mirror images of each other. A number of C-shaped slots are installed at the center and the edge of the component cover plate at the bottom. The C-shaped slots at the center and the C-shaped slots at the edge are both arranged in a circumferential array centered on the center of the component cover plate. The C-shaped slots at the center and the C-shaped slots at the edge correspond one by one and are mirror images of each other. A stator core is inserted into the C-shaped slot, and rounded corner inserts are installed at the top and bottom of the stator core. Arc grooves are provided on the left and right sides of the stator core, and the arc grooves of the stator core are used to wind coils, enabling the stator core to generate electromagnetic induction after the power is turned on. Among them, a number of rounded corner notches are provided on the inner surfaces of the two component cover plates on the side close to each other. The rounded corner inserts are inserted into the rounded corner notches of the component cover plate, enabling the stator core to be better connected to the two component cover plates and not easily slide off.

[0009] Furthermore, the auxiliary component includes a number of flow guiding holes, and the number of flow guiding holes are respectively opened on the sides of the two component cover plates away from each other. The opening of the number of flow guiding holes enables the flow guiding holes to introduce air into the inside of the component cover plate to assist in cooling several parts inside the component cover plate. Among them, the auxiliary component also includes a number of internal thread protrusions, and the number of internal thread protrusions are respectively installed on the sides of the two component cover plates close to each other. The screw holes of the number of internal thread protrusions at the top penetrate the top component cover plate. By using screws to pass through the internal thread protrusions, the two component cover plates can be installed together, improving the connection stability between the component cover plate and the stator core.

[0010] Furthermore, the rotor component includes a rotor body, and a cylindrical rotating shaft is installed at the center of the rotor body. The limiting component includes two special-shaped limiting plates and a limiting chassis. The two special-shaped limiting plates are respectively installed at the top centers of the two component sealing plates on the sides away from each other. The limiting chassis is installed at the bottom of the outer surface of the cylindrical rotating shaft. The limiting chassis and the cylindrical rotating shaft are integrally formed. A limiting top plate is arranged above the limiting chassis.

[0011] Furthermore, the protection component includes a component housing. The left side of the component housing is rotatably connected to a component top plate. A plurality of arc-shaped notches are formed in the top of the component top plate. The plurality of arc-shaped notches are arranged in a circumferential array centered on the component top plate; The positioning component includes four special-shaped slots. The four special-shaped slots are all formed in the inner surface of the component housing. A special-shaped insert block is slidably connected inside the special-shaped slot. A plurality of the special-shaped insert blocks are all fixed on the outside of the outer surface of the component sealing plate. An annular support block is arranged at the bottom of the special-shaped slot. The annular support block is installed on the inner surface of the component housing; By arranging the insertion connection of the special-shaped slot and the special-shaped insert block, the two component sealing plates can be limited, preventing the two component sealing plates from rotating during operation and affecting the working stability of the rotor body; Among them, the annular support block is used to support the component sealing plate and the rotor body, preventing the component sealing plate and the rotor body from falling downward.

[0012] The present invention has the following beneficial effects: (1) By setting the stator mechanism in the present invention, specifically, the stator core at the top is removed, then the stator core with damaged coils is pulled out, then a new stator core is taken out, then the stator core is moved to the top of the bottom component sealing plate, and then the two ends of the stator core are aligned with the two C-shaped slots, and then the stator core is moved downward to insert the stator core into the inside of the C-shaped slot. In this way, the replacement of the stator core can be completed. The steps are simple and conducive to the emergency repair of the motor.

[0013] (2) By setting the rotor mechanism in the present invention, specifically, the rotor body is inserted into the center of the two component sealing plates, and then the rotor body is fixed at the center of the component sealing plates by the limiting chassis and the limiting top plate. In this way, the rotor body can be maintained to rotate at the center, preventing the rotor body from deviating from the center and affecting the working performance of the motor.

[0014] (3) By providing a protection mechanism, specifically, the stator mechanism and the rotor mechanism are placed inside the component housing, and then the component top plate is rotated to seal the top of the component housing. In this way, the parts of the stator mechanism and the rotor mechanism can be protected, preventing them from malfunctioning due to interference such as collisions, and ensuring that the stator mechanism and the rotor mechanism can operate stably.
