Abstract
In a magnetic bearing system, the longitudinal shaft position is shifted relative to the bearing position so that a force can be applied by the bearings away from a node at critical shaft speeds. In one embodiment, the shaft is shifted by end thrust bearings back and forth on an integral cycle basis. Alternatively, closely-spaced bearing pairs may be used and energized alternately on an integral cycle basis in order to shift back-and-forth the region at which the combined effective force of the bearing is applied.
