Noncontact Magnetic Suspension of an Iron Ball Using Flux Path Control Mechanism
This paper proposes a noncontact magnetic suspension of an iron ball using a flux path control mechanism. In this system, the suspension force is generated by a disk-type permanent magnet, and controlled by varying the angle of the permanent magnet that is driven by a rotary actuator. In this paper, first, the suspension principle is explained, and the prototype is introduced. Second, the characteristics of this system are examined by some basic experimental results. Third, a model is created, and the numerical simulation is carried out. Finally, the suspension experiments are succeeded using the prototype, and the results are shown and discussed.
