Development of Flywheel Energy Storage System with Hybrid AMB-SMB
Structure of flywheel rotor for 1 kWh class energy storage system are discussed. The flywheel will be made of CFRP material which is light weight and has high tensile strength. The rotor weighing about 50kg will be supported by superconducting magnetic bearing in axial direction and will accelerate up to 40,OOOrpm with active magnetic bearings assistance in radial direction. By means of natural frequ ency and stability analysis, a structure of rotor that mounted two flywheel disks at both ends of main shaft is proposed. At first step, a manufa cturing prototype of O.2kWh class energy storage was carried out.
