Problems solved by technology

[0004] 1. Large installation size, high requirements for on-site installation conditions of technical transformation projects, and poor adaptability
[0005] 2. The existing known permanent magnet speed governor, permanent magnet brake and permanent magnet load device, because the coupling distance and/or coupling area of ​​the air gap magnetic field constructed between the permanent magnetic disk and the permanent magnetic coupling disk by directly adjusting are Real-time online dynamic changes, so at least one of the passive disk and the driving disk and its transmission shaft is an axial sliding and torque transmission structure, this structure brings great difficulties to product manufacturing and assembly processes The technical indicators such as material and manufacturing precision of key components are relatively strict, the manufacturing process is complicated, and the manufacturing cost remains high; The technical performance requ
