1. Introduction The flywheel energy storage system [1, 2] is a highly promising technology for efficient energy storage, comprising a flywheel rotor , bearings [, , ], vacuum technologies, and motor [, , , , , , ].
While past applications of the flywheel have used conventional mechanical bearings that had relatively high losses due to friction, the development of magnetic bearings constructed using High Temperature Superconductors (HTSC) has greatly decreased the losses due to friction and increased efficiency immensely.
Therefore, a new suspension support method is urgently needed for flywheel energy storage systems to solve these problems. Xiaojun Li presents a novel combination 5-DOF AMB (C5AMB) designed for a shaft-less, hub-less, high-strength steel energy storage flywheel (SHFES), which achieves doubled energy density compared to prior technologies.
