Title: Materials research issues in superconducting levitation and suspension as applied to magnetic bearings

Abstract

Current research issues associated with the improvement of high-temperature superconductor materials for magnetic-bearing applications are discussed. Major parameters of interest include magnetic pressure, magnetic stiffness, and damping. The understanding of and improvement in magnetic flux pinning within individual grains are seen as key to large improvements in the major parameters. The necessary material properties and routes to achieving those properties differ for those applications that require minimization of rotational losses versus those that require large magnetic pressures. Increased attention to characterization of the superconducting materials in terms of the bearing performance properties is desired, and chemical stability and mechanical strength of superconducting grains within a support matrix are recognized as vital success of commercial applications. 46 refs., 4 figs.
