This paper describes a novel type of magnetic suspension system with a permanent magnet and a rotary actuator. The feature of this suspension system is that a rotary actuator controls attractive force. Varing the angle of the permanent magnet driven by the actuator changes magnetic flux path in the suspension system and controls the suspension force. The merit of this suspension system is that the attractive force of this magnetic circuit can be made to be zero. Moreover this system can change the polarity of stator poles. First an outline of the suspension system will be described. Next, the principle of the suspension mechanism will be explained. To verify the feasibility of the proposed system, some basic experiments and a numerical simulation will be shown.
