G1000205 Development of Three-Axis Flux-Path Control Magnetic Suspension System Using Flux Concentration

Abstract

A flux-path magnetic suspension system was fabricated in which the three-degree-of-freedom motions of the floator was actively controlled. In this system, a control plate with four rectangular permanent magnets for magnetic concentration were used instead of ferromagnetic control plates in the conventional flux-path magnetic suspension system to increase the suspension force. The three-degree-of-freedom motions of the control plate were controlled with four differential electromagnetic actuators according to the motions of the floator. Contactless suspension was achieved by applying PD control in the fabricated suspension system.
