Abstract

The apparatus includes a resilient mounting for the damping of magnetic bearings. This mount may include a resilient material placed between the magnetic stator and the fixed structure to damp vibrations of the stator induced by variations in the position of the shaft and rotor of the bearing. Alternatively, the resilient material may be placed between successive concentric magnetic rings of the stator. The resilient material is typically an elastomer or a woven metal material with both stiffness and damping properties. The mounting also may consist of separate spring and damping elements. The spring elements can include thin rods or bars which provide both alignment and stiffness. The damping element may consist of a resilient material or a device to provide damping through viscous or mechanical friction configurations.
