[0017] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0018] This application discloses a mechanical-electromagnetic energy conversion wheel. (Refer to...) Figure 1 A mechanical electromagnetic energy conversion wheel includes a stator structure 1, a rotor structure 2, and a mechanical support and adapter structure 3. The stator structure 1 includes a stator core 11 made of stacked silicon steel sheets, with circumferentially distributed slots 12. Ring windings 13 are embedded within the slots 12, and the ring windings 13 are multiple independent power generation units, improving power generation redundancy and stability. The rotor structure 2 includes a cylindrical permanent magnet 21 and a self-stabilizing support 23. The outer periphery of the cylindrical permanent magnet 21 forms a closed magnetic circuit through a magnetic guide ring 22, enhancing magnetic flux density. The self-stabilizing support 23 connects the cylindrical permanent magnet 21 to an external shaft and employs an elastic adapter structure to automatically compensate for coaxiality deviations and suppress vibration effects. The mechanical support and adapter structure 3 includes an annular base 31 rigidly connected to the stator core 11 and an elastic radial adapter 32 arranged between the external structures of the annular base 31. The annular base 31 provides axial support to ensure the stability of the stator-rotor relative position, and the radial adapter 32 uses an elastic material to attenuate radial vibration transmission.

[0019] The implementation principle of a mechanical electromagnetic energy conversion wheel in this application embodiment is as follows: In use, a stator core 11 with toothed grooves 12 is stamped from silicon steel sheets. After lamination and insulation treatment, an annular winding 13 is wound within the toothed grooves 12 using an automatic winding machine, ensuring that the number of turns and insulation performance are consistent. A cylindrical permanent magnet 21 is fixed to the center of a magnetic ring 22 with anaerobic adhesive. The self-stabilizing support 23 and the magnetic ring 22 are interference-fitted, with pre-loaded elastic compensation stress. The stator core 11 is welded and fixed to the annular base 31. The radial adapter 32 is integrally formed with the annular base 31 through a vulcanization process, ensuring vibration damping performance. External mechanical energy drives the rotor structure 2 to rotate. The magnetic field of the cylindrical permanent magnet 21 cuts the annular winding 13, and multiple windings synchronously generate electricity, outputting alternating current. When there is coaxiality deviation or vibration, the elastic structure of the self-stabilizing support 23 automatically fine-tunes the rotor position, and the radial adapter 32 dampens vibration energy, maintaining the relative position stability of the stator and rotor, ensuring magnetic circuit and power generation efficiency.

[0020] In this process, the utilization rate of magnetic flux and energy conversion efficiency are improved by using a 13-array toroidal winding and a closed magnetic circuit design; multiple independent power generation units enhance the system's reliability and practicality.
