MAGNETIC THRUST BEARINGS

摘要

Rotating machines and magnetic thrust bearings therefor are disclosed. Magnetic thrust bearings may include a rotor core configured to extend coaxially around a shaft of a rotating machine, a non-magnetic element configured to be coaxially disposed on the shaft, and a stator comprising a stator core and a coil, both of which are configured to extend coaxially around the axis. The rotor core may include a substantially radially extending thrust face and a substantially axially extending peripheral surface. The non-magnetic element may radially space the thrust face from the shaft. The stator core may include a substantially radially extending first pole surface and a substantially axially extending second pole surface. The first pole surface may define an axial air gap with the thrust face, and the second pole surface may define a radial air gap with the peripheral surface.

1. A magnetic thrust bearing for a rotating machine having a shaft extending along an axis, the magnetic thrust bearing comprising:
a rotor core configured to extend coaxially around the shaft, the rotor core having a substantially radially extending thrust face and a substantially axially extending peripheral surface; a non-magnetic element configured to be coaxially disposed on the shaft, wherein the non-magnetic element radially spaces the thrust face from the shaft; and a stator comprising a stator core and a coil both configured to extend coaxially around the axis, wherein the stator core comprises a substantially radially extending first pole surface and a substantially axially extending second pole surface, the first pole surface defines an axial air gap with the thrust face, and the second pole surface defines a radial air gap with the peripheral surface.
