In the flux-path control magnetic suspension system, the force acting on the floater is controlled by moving a control plate made of ferromagnetic material, which is located between the permanent magnet and the floater. In this paper, the three-dimensional attractive forces acting on the floator were measured with a manufactured load cell and two sets of plate springs with strain gauges. The force actuating in the vertical direction is measured with the load cell. The force actuating in the horizontal direction is measured with the plate springs with strain gauges. These measurements clarify the relations between the positions of the control plates and the three-dimensional attractive forces. In addition, stable three-dimensional positioning was achieved by applying PD control. PD control is also applied to the flux path control modules to provide them sufficient stiffness and damping property to suspend the floator. In addition, several dynamic characteristics were measured in each direction.
