Description
Technical Field

Background
Permanent magnet eddy current speed regulator, permanent magnet speed regulator for short, has been widely used in recent years as non-mechanical connection transmission device, and torque transmission between prime mover and working machine can be realized by means of magnetic induction principle of permanent magnet, eddy current ring and eddy current disk. Compared with other transmission modes, the product has the excellent characteristics of soft start, soft connection, overload resistance, no resonance, torque self-adaption and the like.
The structure of the permanent magnet speed regulator widely used at present is mainly a cylinder type permanent magnet speed regulator. The conventional are a magnetic-copper-magnetic structure and a copper-magnetic-copper three-cylinder structure.
