This invention uses multiple heat sinks, which can effectively absorb and dissipate heat to prevent the motor from degrading due to overheating and maintain the stability of the motor's output torque and speed. Therefore, we propose a high-efficiency heat dissipation magnetic flywheel. Utility Model Content

[0031] Furthermore, friction rings 20, which are symmetrically arranged in a ring shape, are fixed on the cylindrical surface of the rotating shaft 7. The friction rings 20 are provided with connecting holes 21. The ends of the threaded connecting rods 8 are inserted into the connecting holes 21 from top to bottom, and the ends of the threaded connecting rods 8 are fixed with nuts.
