Therefore, the weight of the driven magnetic wheel transmission part (12) is fixed on the rotation track of the drawer transmission shaft (13) connected thereto, and the almost unloaded axis core is used to support against the magnetic levitation line direction, forming the entire driven magnetic wheel transmission part (12) suspended on the fixed operation track.

At the same time, the magnetic force is greatly enhanced. For the traditional parallel or vertical magnetic levitation, in order to prevent the problem of excessive attractive force, the magnetic force is very limited. Generally, it cannot operate under a gas pressure of 0.5 Mpa. However, the magnetic force of the circumferential magnetic levitation solves the problem of excessive magnetic force causing attraction, and the magnetic force is greatly enhanced.
