Abstract
A full levitation magnetic bearing system with passive magnetic bearings that affords increased radial stiffness and load capacity includes two passive permanent magnet magnetic bearings, one each located on each side of the center of mass of the rotor to be levitated. An active axial magnetic bearing provides control for stable levitation. The magnetic bearing system provides increased radial stiffness and load capacity by the reduction or elimination of the unstable tilting moments generated by the individual passive permanent magnet magnetic bearings. The bearings are constructed so that they are concave toward the center of the rotor, with a radius approximately equal to the distance between the magnetic bearing and the central point about which tilt rotation would tend to occur. The individual magnetic air gaps are preferably constructed to be perpendicular to the axis of rotation.
