Synchronous magnetic coupling working principle:
Through the interaction of the permanent magnet magnetic field generated by the permanent magnet, a new type of coupling with a protection function is connected to the driving end and the load end. The powerful magnetic field of the rare earth permanent magnet is used to interact, and the torque is transmitted in the air, so as to realize soft start and soft connection.
*All drum magnetic coupling is Synchronous magnetic coupling.
