Feasibility Analysis of Two Iron Balls' Simultaneous Suspension Using Flux Path Control Mechanism

Abstract

This paper proposes a noncontact magnetic suspension system for levitating two different weight iron balls simultaneously 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 controllability is proved, theoretically. Finally, the numerical simulation results of suspension are shown and discussed.
