Abstract
Hybrid superconducting magnetic bearing(SMB), using YBCO high temperat ure superconductors(HTS) coupled with permanent magnets, has been impl emented into a flywheel energy storage(FES) system prototype. The hybr id SMB design uses permanent magnets to levitate the rotor weighing 19 kg and superconductors to stabilize the inherently unstable magnet-ma gnet interactions. The SMB bearings are brought into action under conv enient field-cooled conditions. Spin-down performance of the construct ed FES prototype was tested under a moderate vacuum.
