The magnetic wheel speed regulator is suitable for low wear scenes.
[0003] At present, with the wide application of the permanent magnet transmission technology and the increasing demand of energy saving and emission reduction, the power requirement of the permanent magnet speed regulator is higher and higher, therefore, the floor application of the permanent magnet speed regulator can develop towards a larger power, and the mainstream way to improve the power of the permanent magnet speed regulator is to increase the outer diameter or the axial length of the rotor, so that the volume of the permanent magnet speed regulator is larger and larger, and the installation difficulty and the application limitation are caused. Therefore, the application provides the cylinder type magnetic wheel speed regulator based on the high-strength magnetic circuit arrangement structure to solve the above problems. SUMMARY

[0009] The permanent magnet layer comprises a plurality of groups of permanent magnets, the plurality of groups of permanent magnets are annularly and uniformly distributed, and adjacent groups of the permanent magnets are opposite in the same polarity, so that the magnetic field lines emitted by the same magnetic pole of each group of permanent magnets are all diverged outward to form a closed loop;
[0010] Each group of the supporting body layers can be connected into one group of the gap, so that the magnetic field lines generated by the permanent magnet layer pass through the conductor layer.

[0052] A limiting ring 23 is distributed outside the permanent magnet layer 22. The limiting ring 23 forms an isolation barrier for multiple permanent magnets 221. The limiting ring 23 is made of non-magnetic materials such as titanium alloy or non-magnetic stainless steel.
