Abstract
In a superconducting bearing, flux density and flux density gradient are increased between a magnetic source and a member of superconducting material. A plurality of magnets are magnetized end-to-end and stacked side-by-side in alternating polarity. Non-magnetic shims are disposed between the magnets. Flux lines flow between the ends of adjacent magnets and communicate with the member. Resulting is higher bearing load capacity and stiffness. When the member is made from a Type II superconducting material, the bearing provides support in both the radial and axial directions.
