Problems solved by technology

[0003] During the implementation and promotion of the above-mentioned permanent magnetic coupling patents, we found that there is an urgent problem to be solved, that is, all current permanent magnetic couplings (PMC), permanent magnetic coupling speed controllers (PMD), permanent magnetic coupling speed control couplings The permanent magnetic coupling automatic transmission, permanent magnetic coupling brake device, permanent magnetic coupling load / loading device and permanent magnetic coupling clutch all realize the axial adjustment between the active rotor disc and the passive rotor disc through the permanent magnetic coupling axial displacement adjustment mechanism. The change of the axial relative position of the permanent magnetic coupling assembly, so as to realize the change of the air gap distance and the air gap coupling area in the permanent magnetic coupling assembly, to adjust the magnetic torque generated by the permanent magnetic induction magnetic field, to achieve the purpose of adjusting the transmission rotation or braking torque, and then complete the transmission Functions such as speed regulation and torque conversion, braking and loading; the permanent magnetic coupling axial displacement adjustment mechanism has the advantage of simple structure, but the whole system occupies a large axial space, and the axial installation space is narrow and the system is due to various For these reasons, it is difficult to meet the application requirements of mobile motors and equipment, and the current permanent magnetic coupling devices of the known technology are not competent. Therefore, it is necessary to develop a new permanent magnetic coupling adjustment technology to meet market needs and technological progress.
