Abstract :
Superconducting bearings promise to reduce friction by up to two orders of magnitude, auguring flywheels in the 10-kWh class. The author discusses the principles of stable magnetic levitation of permanent magnets using superconductors. The author then discusses the application of the principles to bearings using high temperature superconductors. Key design parameters and application to flywheels are also discussed
