    摘要: A magnetic bearing and positioning system provides a radial actuator for positioning a shaft without mechanical contact between the actuator and the shaft. As disclosed, the actuators use a homopolar structure without slots between the poles and with the poles of the magnetic bearing being at the same polarity at a given axial position, thereby advantageously reducing hysteretic and eddy current losses in the rotor material.

    摘要: The present invention contemplates a combination bearing for supporting a rotating rotor within a gas turbine engine. The combination bearing including a magnetic bearing system and dry solid lubricated rolling element auxiliary bearings units for sharing the shaft load. The rotating central shaft being normally supported by the active electromagnetic bearing system. The auxiliary bearing unit being soft mounted to the shaft and engine housing and rotatable with the shaft. Soft mounting of the bearings between the housing and the shaft allows a substantially stable transition from the all magnetic bearing support to a physically contacting mechanically assisted support of the shaft.
