ABSTRACT:
A magnetic bearing has a number of pole pieces disposed about the circumference of the shaft supported by the bearing. To inhibit magnetic flux migration within the bearing, magnetic barriers of non-magnetic material are interposed between pole pieces at selected locations. Magnetic guides prevent magnetic saturation of the bridging portion of the pole pieces prior to the poles' saturating.
