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 requirements of configuring the actuator are relatively high
[0006] 3. In the speed regulation section of 35-75% of the rated speed, the permanent magnet coupling component of the existing permanent magnet speed governor is seriously heated, and it is easy to generate local high heat during use, so it cannot be applied to occasions with high explosion-proof requirements ; On the other hand, when the coupling air gap distance of the permanent magnetic coupling component is large or the coupling area is small (less than 70% of the adjustment stroke section), the system vibration is large, which will cause serious consequences of poor reliability
[0007] 4. The known permanent magnet speed governor cannot realize the speed-up adjustment function, which limits the application field of permanent magnet speed regulation technology
[0008] 5. The known permanent magnet speed regulation, braking and load devices have complex structures and poor reliability
