ACTIVE MAGNETIC BEARING ASSEMBLY AND ARRANGEMENT OF MAGNETS THEREFOR

摘要

The subject matter described herein includes an active magnetic bearing assembly. The active magnetic bearing assembly includes a rotor configured to rotate with the shaft of a rotating machine. The active magnetic bearing assembly includes a stator that circumferentially surrounds the rotor and remains stationary. The assembly further includes a plurality of magnets coupled to the stator and circumferentially placed from each other about the stator. Each magnet has an inner portion and an outer portion. The inner portion is radially closer to the rotor than the outer portion. The inner and outer portions are of different material or shape from each other.
