提出了一种新颖的磁通控制磁悬浮系统，该系统将控制板放置在磁源（永磁体）旁边。在传统的磁通路径控制磁悬浮系统中，控制板插入磁源和悬浮物体（浮子）之间。相反，在所提出的系统中，控制板放置在磁源旁边。在这种构造中，有效间隙变得比传统系统中的更大。对所提出的磁悬浮系统的基本特性进行了数值和实验研究。数值分析表明，随着侧向环形控制板位置的增加，作用在浮子上的吸引力增大。吸引力的变化足以稳定悬架系统。还表明，可以通过将板分成两半并以不同的方式移动它们来产生侧向力。预测的特性在具有三轴力传感器和间隙调节机构的制造装置中通过实验得到证实。
A novel flux control magnetic suspension system that places control plates beside the magnetic source (permanent magnet) is proposed. In a conventional flux-path control magnetic suspension system, the control plates were inserted between the magnetic source and the suspended object (floator). In contrast, the control plates were placed beside the magnetic source in the proposed system. In such a configuration, the effective gap becomes larger than in the conventional system. Basic characteristics of the proposed magnetic suspension system were studied both numerically and experimentally. The numerical analyses show that the attractive force acting on the floator increases as the position of the lateral ring-shape control plate increases. The variation of the attractive force is sufficient for the stabilization of the suspension system. It is also shown that lateral force can be generated by dividing the plates into halves and moving them differentially. The predicted characteristics are confirmed experimentally in a fabricated apparatus with a three-axis force sensor and a gap adjustment mechanism.
