[0002] The permanent magnet speed regulator is a device in which the conductive material on the conductor disk cuts the magnetic lines of force on the permanent magnet disk, generating eddy currents to form an induced magnetic field. The permanent magnetic field and the induced magnetic field interact with each other to transmit torque. The current existing permanent magnet speed regulator changes the gap between the conductor disk and the permanent magnet disk of the permanent magnet speed regulator to achieve changes in output speed and output torque. However, in practice, when the permanent magnet speed regulator is working, both the conductor disk and the permanent magnet disk are rotating at high speed. How to adjust the gap between the high-speed rotating permanent magnet disk and the conductor disk becomes very difficult; the current mainstream design structure is to achieve the above-mentioned adjustment through the speed regulating inner and outer sleeve structure, which requires that the structural design of the speed regulating inner and outer sleeve, bearings, etc. must be very precise, and the subsequent maintenance amount is large; and the above-mentioned structure also limits the further development of the permanent magnet speed regulator.
