This paper describes a new type of magnetic suspension system using a rotary geared motor and a disk magnet. In this suspension system, the suspension force is provided by a disk-type permanent magnet and is controlled by a magnetic flux path control mechanism, which rotates the disk magnet to change the flux passing through the suspended object. This suspension system may realize zero attractive force to avoid the uncontrollable adhesion, changing the polarity of the stator poles for complex applications, and zero-power levitation with the constant air gap. In this paper, suspension principle and the experimental prototype of this proposed system are introduced, the basic experiments using the prototype are examined, and the modeling and simulation are carried out. Finally, some suspension experiments for verifying the suspension performance are executed.
