Development of Lorentz Force Type Magnetic Bearing

Abstract:

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.
