A rotating machine with active magnetic bearings (AMBs) requires conventional bearings as a backup support system in the case of AMB failure. This paper presents an estimated auxiliary/catcher bearing (CB) L10 fatigue life based on the Hertzian conta

Conventional use of magnetic bearings relies on a zero reference to keep the rotor centered in the radial and axial axes. This paper compares different control methods developed for the alternate control task of tracking an axial dynamic target. Cont
