The development of a flywheel energy storage system using superconducting magnetic bearings

Abstract

The Railway Research Institute has been developing a superconducting flywheel energy storage system for regenerative energy. Its flywheel is supported by a superconducting magnetic bearing using a superconducting coil as a stator and bulk superconductors as a rotor. I have designed and manufactured an experimental apparatus based on this structure and have demonstrated the feasibility of the structure.
