Abstract :
A flywheel cell intended for multi-flywheel cell based energy storage system is proposed. The flywheel can operate at very high speed in magnetic levitation under the supports of the integrated active magnetic bearing and a passive magnetic bearing set. 3D finite element analyses were applied to verify various configurations of passive magnetic bearing. The feasibility of PID controllers for the flywheel cell was evaluated by simulation study.
