This paper investigates the control system design of magnetic forces using independent motion control of permanent magnets. In the permanent magnet bearing system, the radial motions of the rotor are passively supported by repulsive forces between ring-shape permanent magnets. The experimental results demonstrate that non contact levitation is achieved by independently PD controlled axial motion of permanent magnets driven by voice coil motors (VCM).
