[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] This utility model provides, for example Figure 1-4 As shown, a modular plastic magnetic rotor that facilitates quick component replacement includes a central connecting shaft 2 and a stator core 1 disposed at a position outside the central connecting shaft 2;

[0023] An annular threaded groove 12 is provided on the outer side of the central connecting shaft 2. A movable connecting ring 9 is provided on the outer side of the annular threaded groove 12. A movable pressing slope block 10 is provided on the side of the movable connecting ring 9. The movable pressing slope block 10 is rotatably connected to the movable connecting ring 9. A movable connecting groove 11 is provided on the outer side of the movable pressing slope block 10. A movable snap fastener 13 is provided at the end of the movable connecting groove 11. The bottom side of the movable snap fastener 13 is a slope structure. A snap-fit ​​connecting groove 16 is provided on the inner side of the stator core 1. In use, rotating the movable connecting ring 9 drives the movable pressing slope block 10 to move along the movable connecting groove 11. The movable pressing slope block 10 will press the movable snap fastener 13 so that it snaps into the snap-fit ​​connecting groove 16. Reverse rotation of the movable connecting ring 9 connected to the reset spring can reset the movable snap fastener 13. Through the improvement of this utility model, the assembly, connection and disassembly of the modular plastic magnetic rotor can be made faster, thereby effectively improving the practicality of the modular plastic magnetic rotor.

[0024] like Figure 3 As shown, the inner side of the movable connecting ring 9 is provided with an internal thread. The movable connecting ring 9 and the annular threaded groove 12 are rotatably connected by the thread. The movable connecting ring 9 can maintain a certain position and be limited after rotation by the action of the thread.

[0025] like Figure 2 As shown, a central mounting connection hole 3 is provided at the middle position of the stator core 1. The inner diameter of the central mounting connection hole 3 is equal to the outer diameter of the central connecting shaft 2. The central mounting connection hole 3 is provided for connecting the central connecting shaft 2.

[0026] like Figure 4 As shown, a limiting moving post 14 is provided on the side of the movable card buckle 13. The limiting moving post 14 and the movable card buckle 13 are an integral structure. A limiting moving groove 15 is provided on the outer side of the limiting moving post 14. The length of the limiting moving groove 15 is the moving range of the limiting moving post 14.

A permanent magnet 8 is connected to the middle of the rotor teeth 6, and a non-magnetic support 7 is located on the outer side of the rotor teeth 6. When the rotor armature winding 4 is energized, the current-carrying conductor experiences a torque due to the Lorentz force in the stator magnetic field, driving the rotor to rotate. The permanent magnet 8, through rare-earth materials such as neodymium iron boron, forms a constant magnetic field, achieving non-contact coupling with the rotating magnetic field generated by the rotor armature winding 4. This design eliminates the brush slip ring structure, increasing the magnetic field strength by more than 30% without excitation energy consumption.
