Flux-path control magnetic suspension using flux concentration is proposed and studied both analytically and experimentally. The proposed system used control plates made of permanent magnet instead of ferromagnetic material. It was shown that flux-concentrated type can produce larger suspension force than the conventional flux-interrupted type. However, it was difficult to achieve stable suspension since the control (variable) force was not so large. In this paper, to solve such a problem, the characteristics of the suspension system are studied by finite element analysis. The effects of the direction of motion, the operating positions and the shape of the control plates are investigated. An experimental apparatus with a variable flux-path unit using flux concentration is developed based on the analytical result. A single-axis stable suspension is achieved by applying PD control in the developed apparatus.
