Abstract
A magnetic thrust bearing is designed for use in a pumping system that includes a pump driven by a motor through a shaft. The magnetic thrust bearing includes one or more platters that remain stationary with respect to the shaft and one or more thrust discs connected to the shaft and interleaved with the one or more platters. Each of the one or more platters includes a plurality of platter magnets and each of the one or more thrust discs includes a plurality of thrust disc magnets. The magnets on the platters and thrust discs are configured to produce repulsive magnetic forces as the thrust discs approach the platters.
