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 governors, permanent magnet brakes and permanent magnet loaders are due to directly adjusting the coupling distance and / or The coupling area is realized, where the relative position between the passive disk and the driving disk is dynamically changed online in real time, so at least one of the passive disk and the driving disk and its transmission shaft are axially sliding and transmitting the torque structure, This structure brings great difficulties to the product manufacturing and assembly process, and has relatively strict requirements on the technical indicators such as the material and manufacturing precision of key components, the manufacturing process is complicated, and the manufacturing cost remains high; at the same time, this structure is not conducive to vertical Manufacture of type permanent magnet speed governor, and the adjustment torque is also relatively large, which requires high technical performance of the configured actuator
[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
