Abstract
A magnetic bearing wherein a stator is magnetically interacted with a rotor and is movable in response to feed-back of rotor position to thereby use the magnetic interaction between the stator and rotor to effect movement of the rotor toward a predetermined rotor position for bearingly controlling the rotor position. The bearing may be a radial or thrust bearing.
Claims20
A bearing for a rotor comprising a stator, means for magnetically interacting said stator with the rotor, and means responsive to feed-back of a rotor position for moving said stator relative to the rotor position to thereby use changes in forces of the magnetic interaction between said stator and the rotor resulting from movements of the stator relative to the rotor position to effect movement of the rotor toward a predetermined rotor position for bearingly controlling position of the rotor.
A bearing for a rotor comprising a stator which circumscribes the rotor, means for magnetically interacting said stator with the rotor, and means responsive to feed-back of a rotor radial position for moving said stator radially relative to the rotor radial position to thereby use chances in forces of the magnetic interaction between said stator and the rotor resulting from movements radially of the stator relative to the rotor radial position to effect movement of the rotor radially toward a predetermined rotor radial position.
A method for bearingly controlling position of a rotor comprising magnetically interacting a stator with the rotor and moving the stator relative to a rotor position in response to feed-back of the rotor position to thereby use changes in forces of the magnetic interaction between the stator and the rotor resulting from movements of the stator relative to the rotor position to effect movement of the rotor toward a predetermined rotor position.
