Abstract
This paper describes a 2 DOF magnetic suspension system for an iron stick type object using a rotary geared motor and a disk magnet. In this system, the suspension force is provided by a disk-type permanent magnet and is controlled by a magnetic flux path control mechanism. This suspension system must control two degrees of freedom of an iron stick for complete noncontact suspension. A vertical displacement and a horizontal rotation of the object should be controlled. This paper proves the feasibility of the noncontact suspension system for such a system by controlling these two movements simultaneously. A theoretical analysis will be done on the model of this suspension system and a numerical simulation validate the feasibility of the system.
