| Research Abstract |
This research focused on an electric power storage flywheel. In order to make rotational loss small, the Lorentz force type magnetism bearing was developed, and it applied to the small electric power storage flywheel. The fabricated experimental setup achieved stable rotor levitation control in the range up to 3000r/min. Moreover, the free-run experiment was carried out in order to compare the deceleration characteristics of a magnetic bearing and a ball bearing. The proposed Lorentz force type magnetism bearing showed clearly that a rotation loss can be reduced in one-third compared with the ball bearing.
