Abstract

In this study, an improved centripetal force type-magnetic bearing (CFT-MB) for a flywheel battery system is proposed, which is easy to process and it has better performance with superior stiffness and anti-interference characteristics than that of the pure spherical CFT-MB. First, the configuration, magnetic circuits, working principle and mathematical model of the improved CFT-MB are analyzed in detail. The electromagnetic characteristics are then analyzed. In comparison with the analysis results of the pure spherical CFT-MB, the improved CFT-MB has less cost, less force–displacement and force–deflection stiffness, and higher force-current stiffness, which verify its preferable design concept. Related comparative experiments based on the prototype are also conducted. The stiffness tests results verify the accuracy of the previously presented electromagnetic characteristic analysis results. Performance tests results show that the proposed improved CFT-MB is superior to that of the original CFT-MB in resisting to the disturbance or the gyroscopic effect, which verifies the accuracy of the theoretical analysis.
