초록

The present invention contemplates a hybrid magnetic bearing thrust disk. In one embodiment the hydrid magnetic bearing thrust disk comprises a high magnetic permeable portion that is supported by a high specific strength circumferential ring. The high specific strength circumferential ring resisting the dynamic loads applied to the hydrid thrust disk.
