Abstract
A coast-down bearing and method for a magnetic bearing system is provided. The bearing includes first, second, and third rings disposed around a shaft. The first, second, and third rings each have an inner diameter that is greater than an outer diameter of the shaft and provide a running clearance therebetween. The first, second, and third rings are eccentrically positioned with respect to each other to form a pocket for receiving the shaft during a drop, radial shock, or both.
