铅电池主要用于能量储存。然而，他们正在使用化学品和重型材料，这将对环境造成严重影响。因此，正在开发使用磁轴承的清洁能量存储系统。然而，涡流会对储能飞轮造成严重的旋转损耗。为此，提出了洛伦兹力型磁轴承。由于气隙中的恒定磁通，旋转损耗预计可以忽略不计。为了确认建议的磁轴承的操作，制作的实验装置和基本特性进行了测试。转子飞轮最大振幅可达0.65 mm，最高可达3000 min-1。
Lead batteries are used mainly for energy storage. However they are using chemicals and heavy materials, which will affect to environment badly. Therefore, clean energy storage systems are under development using magnetic bearing. However, the eddy current causes serious rotational loss for energy storage flywheel. Therefore, Lorentz force type magnetic bearing is proposed. The rotating loss is expected to be negligible due to the constant flux in the airgap. To confirm the operation of proposed magnetic bearing, an experimental setup is fabricated and basic characteristics are tested. The rotor flywheel could run-up to 3000 min-1 with 0.65 mm maximum amplitude.
