Description

Technical Field

[0001] This utility model relates to the field of stator core technology, specifically a high-permeability magneto stator core. Background Technology

[0002] The stator core is an important component of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and rotor, it forms the complete magnetic circuit of the motor. In asynchronous motors, the magnetic flux in the stator core is alternating, thus generating core losses.

[0003] Chinese utility model patent application number 202322158308.6 provides a stator core for an electric motor. By setting up a disassembly mechanism, multiple stator bodies can be disassembled from the core body, thereby enabling the cleaning of dust from each stator body and the gaps, ensuring the normal use of the core body and the stator body. By setting up a heat dissipation mechanism, the heat generated by the motor can be isolated, preventing the heat generated by the motor from affecting the stator body and the core body, thereby improving the service life of the stator body and the core body.

[0004] However, during the use of the above equipment, it was found that the stator body is mainly used for winding, while the disassembly mechanism of the equipment includes many components such as springs, sliders, and long rods. Moreover, the components of the disassembly mechanism are all located inside the iron core body. When a component such as a spring or slider malfunctions or is damaged, it affects the disassembly and installation of the stator body. Since the component is installed inside the iron core body, it is difficult for maintenance personnel to open it for maintenance, which increases the difficulty and cost of maintenance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-permeability magnetic motor stator core, which solves the problem mentioned in the background technology that components are installed inside the core body, making it difficult for maintenance personnel to open and perform maintenance, resulting in high operational difficulty and increased maintenance difficulty and cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-permeability magnetic motor stator core, comprising a stator core body, an annular array of mounting grooves on the inner side of the stator core body, in which a matching winding component is slidably mounted, the winding component being detachable; rotating grooves are formed on the circumference of the outer surfaces at both ends of the stator core body, and connecting components are provided in the rotating grooves; limit rings are installed at both ends of the stator core body, and connecting grooves with a fan-shaped cross-section are formed on the circumference of the limit rings; a connecting plate is provided on the side of the connecting groove closest to the stator core body, and a fan-shaped slot is formed on the connecting plate; the connecting component includes a helical rod, the outer surface of which fits against the slot, and a nut is helically mounted on the helical rod.

[0007] Preferably, both ends of the stator core body are provided with positioning grooves, the positioning grooves are circular, and the outer diameter of the positioning grooves is larger than the edge of the mounting groove.

[0008] Preferably, a positioning ring is provided on one side of the limiting ring, and the positioning ring is adapted to the positioning groove.

[0009] Preferably, the connecting assembly includes a rotating frame, which is C-shaped and rotatably mounted on a rotating arm. The rotating arm is fixedly mounted on the inner wall of the rotating groove, and the helical rod is fixedly mounted on the outer surface of the rotating frame.

[0010] Preferably, a limiting piece is fixedly provided at the end of the screw rod away from the rotating frame, and the diameter of the limiting piece is larger than the diameter of the screw rod and smaller than the diameter of the connecting groove.

[0011] This invention provides a high-permeability magnetic motor stator core. It has the following advantages:

[0012] (1) This utility model uses a connecting component to install the limiting ring at both ends of the stator core body to restrict the winding component. When the winding component or other components have problems, the connection of the limiting ring can be disconnected, which facilitates the inspection and replacement of the problematic component and reduces the difficulty and cost of maintenance.

[0013] (2) By setting a positioning ring, the positioning ring and the positioning groove are matched, so that the limiting ring can quickly find the correct position during installation and directly snap into the corresponding position without repeated adjustment and alignment, which greatly shortens the installation time and improves the efficiency of reassembly after maintenance.

[0014] (3) By setting a rotating arm, a rotating frame and a limiting plate, the combination of the rotating arm and the rotating frame allows the screw rod to rotate flexibly and adjust its position. When installing the limiting ring, the screw rod can be easily aligned with the fan-shaped groove on the limiting ring connecting plate. When disassembling, the screw rod can also be quickly disengaged from the groove. The limiting plate restricts the axial movement range of the nut on the screw rod, preventing the nut from coming off the screw rod during installation and disassembly, and avoiding loss of the nut.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example 1:

[0026] Please see Figures 1-5This utility model provides a high-permeability magnetic motor stator core, including a stator core body 1. The inner side of the stator core body 1 is provided with an annular array of mounting grooves 12. A matching winding component 4 is slidably installed in the mounting grooves 12. The winding component 4 is detachable. Rotating grooves 11 are provided on the periphery of the outer surface of both ends of the stator core body 1. A connecting component 3 is provided in the rotating grooves 11. Limiting rings 2 are installed on both ends of the stator core body 1. A connecting groove 21 with a fan-shaped cross section is provided on the periphery of the limiting rings 2. A connecting plate 211 is provided on the side of the connecting groove 21 close to the stator core body 1. A fan-shaped slot 212 is provided on the connecting plate 211. The connecting component 3 includes a spiral rod 33. The outer surface of the spiral rod 33 fits against the slot 212. A nut 34 is spirally installed on the spiral rod 33.

[0027] Both ends of the stator core body 1 are provided with positioning grooves 13. The positioning grooves 13 are circular and the outer diameter of the positioning grooves 13 is larger than the edge of the mounting groove 12.

[0028] A positioning ring 22 is provided on one side of the limiting ring 2, and the positioning ring 22 is adapted to the positioning groove 13.

[0029] Specifically, the stator core body 1 has positioning grooves 13 at both ends, and a positioning ring 22 is provided on one side of the limiting ring 2. The positioning ring 22 is adapted to the positioning groove 13. When the limiting ring 2 is installed, the positioning ring 22 is inserted into the positioning groove 13 to realize the quick positioning of the limiting ring 2 and make the connecting groove 21 correspond to the rotating groove 11. This facilitates the fitting of the spiral rod 33 in the connecting assembly 3 with the fan-shaped slot 212 on the connecting plate 211 of the limiting ring 2. Then, by rotating the nut 34 spirally installed on the spiral rod 33, the nut 34 is tightly connected to the connecting plate 211, so that the limiting ring 2 is connected and fixed to the stator core body 1.

[0030] The cooperation between the positioning ring 22 and the positioning groove 13 ensures that the limiting ring 2 is accurately installed in the predetermined position, ensuring the relative positional accuracy between the limiting ring 2 and the stator core body 1. At the same time, the fit between the helical rod 33 and the fan-shaped slot 212, as well as the tightening effect of the nut 34, further ensures the accuracy and stability of the connection, enabling the limiting ring 2 to accurately restrict the winding component 4.

[0031] When it is necessary to repair or replace the winding component 4 or other components, simply unscrew the nut 34, separate the spiral rod 33 from the fan-shaped slot 212, and then pull the positioning ring 22 of the limiting ring 2 out of the positioning slot 13. This allows for easy disassembly of the limiting ring 2 and subsequent operation of the internal components. This is convenient and quick, reducing the difficulty and cost of maintenance. At the same time, the limiting ring 2 has a simple structure and is not prone to failure. Its easy disassembly function facilitates the replacement of the limiting ring 2.

[0032] Furthermore, to improve ease of operation and prevent parts from being lost, please refer to [link / reference needed]. Figures 1-5 The connecting assembly 3 includes a rotating frame 32, which is C-shaped and rotatably mounted on a rotating arm 31. The rotating arm 31 is fixedly mounted on the inner wall of the rotating groove 11, and the spiral rod 33 is fixedly mounted on the outer surface of the rotating frame 32.

[0033] A limiting piece 35 is fixedly provided at the end of the screw rod 33 away from the rotating frame 32. The diameter of the limiting piece 35 is larger than the diameter of the screw rod 33 and smaller than the diameter of the connecting groove 21.

[0034] Specifically, the rotating frame 32 is C-shaped and rotatably mounted on the rotating arm 31, allowing the rotating frame 32 to rotate flexibly relative to the rotating arm 31, which facilitates the position adjustment of the screw rod 33. When installing and removing the limiting ring 2, the screw rod 33 can be aligned with the fan-shaped slot 212 on the connecting plate 211 or taken out from the slot 212 by rotating the rotating frame 32, which improves the convenience of operation.

[0035] The function of the limiting piece 35 is to prevent the nut 34 from coming off the screw rod 33 during installation or use. When the nut 34 is tightened or loosened on the screw rod 33, the limiting piece 35 can limit the axial movement range of the nut 34, ensuring that the nut 34 is always on the screw rod 33, and preventing the nut 34 from being lost.

[0036] Working principle: The winding component 4 is installed into the mounting groove 12 inside the stator core body 1 by sliding. The positioning ring 22 on one side of the limiting ring 2 is aligned with the positioning grooves 13 at both ends of the stator core body 1 and inserted to achieve quick positioning of the limiting ring 2. At this time, the connecting groove 21 corresponds to the rotating groove 11. The rotating frame 32 is rotated so that the spiral rod 33 fixed on the outer surface of the rotating frame 32 is aligned with the fan-shaped groove 212 on the connecting plate 211 and fits. The nut 34 is controlled to rotate so that the nut 34 is tightly connected to the connecting plate 211, thereby connecting and fixing the limiting ring 2 to the stator core body 1.

[0037] When it is necessary to repair or replace the winding component 4 or other components, first unscrew the nut 34, then rotate the rotating frame 32 to remove the spiral rod 33 from the fan-shaped slot 212, and then pull the positioning ring 22 of the limiting ring 2 out of the positioning slot 13. The limiting ring 2 can then be disassembled, and the internal components can be repaired or replaced accordingly.
