A novel flux control magnetic suspension system that places control plates beside the\nmagnetic source (permanent magnet) is proposed. In a conventional flux-path control magnetic\nsuspension system, the control plates were inserted between the magnetic source and the suspended\nobject (floator). In contrast, the control plates were placed beside the magnetic source in the proposed\nsystem. In such a configuration, the effective gap becomes larger than in the conventional system.\nBasic characteristics of the proposed magnetic suspension system were studied both numerically and\nexperimentally. The numerical analyses show that the attractive force acting on the floator increases\nas the position of the lateral ring-shape control plate increases. The variation of the attractive force\nis sufficient for the stabilization of the suspension system. It is also shown that lateral force can\nbe generated by dividing the plates into halves and moving them differentially. The predicted\ncharacteristics are confirmed experimentally in a fabricated apparatus with a three-axis force sensor\nand a gap adjustment mechanism.
