摘要：
A magnetic bearing system using forces of repulsion between permanent magnets was developed. In the developed magnetic bearing, the radial motions of the rotor are passively supported by repulsive forces. The motion in the axial direction, which is inherently unstable, is stabilized by using the motion control of the permanent magnets for passive radial suspension with a piezoelectric actuator. The developed magnetic bearing suspended a rotor without any mechanical contact. The characteristics of the suspension system were studied both theoretically and experimentally.
