    摘要： A magnetic bearing system for enabling translational motion includes a carriage and a shaft for movably supporting the carriage; a first magnetic bearing fixed to one of the carriage and shaft and slidably received in a first channel of the other of the carriage and shaft. The first channel is generally "U" shaped with two side walls and a back wall. The magnetic bearing includes a pair of spaced magnetic pole pieces, each pole piece having a pair of electromagnetic coils mounted on poles on opposite ends of the pole piece proximate the side walls, and a third electromagnetic coil mounted on a pole of the pole piece proximate the backwall; a motion sensor for sensing translational motion along two axes and rotationally about three axes of the carriage and shaft relative to each other; and a correction circuit responsive to the sensor for generating a correction signal to drive the coils to compensate for any misalignment sensed between the carriage and the shaft.

    摘要： A magnetic suspension system for a rotary machine including two magnetic actuators spaced from each other. Each actuator includes a stator which has a support shell with a plurality of coil windings, and a rotor which has an inclined annular gap for rotatably receiving the shell and a device for providing a magnetic field in the gap. The system selectively excites the coils to interact with the magnetic field in each gap and produce Lorentz forces for suspending the rotor of each actuator.
