感应悬浮器是一种产生斥力的装置，这种斥力是由于受激线圈和它们在其他导电元件中产生的涡流之间的相互作用而产生的。像这样的机器已经被提议作为非接触式运输系统（MAGLEV）的悬浮机制[1,2]，或作为磁性轴承[3]。在本文中，我们介绍了感应悬浮的小型实验室模型的研究（图1）。测量值与有限元分析得到的计算值进行了比较。次级系统由一个导电板组成，如果需要，可以用铁支撑，详细的测量和计算说明了次级系统的形状和大小对力（升力和横向）和功率因数的影响。然后对50吨磁悬浮车辆的悬浮系统进行了计算研究。
Induction levitators are devices which produce repulsion as a result of the interaction between excited coils and the eddy currents which they induce in some other conducting member. Machines such as this have been proposed as the levitation mechanism for contactless transport systems (MAGLEV)[1,2], or as magnetic bearings [3]. In this paper we present studies of small laboratory models of induction levitators (Fig 1). Measurements are compared with calculated values obtained by a finite element analysis. The secondary consists of a conducting plate which could be backed by iron if required, and detailed measurements and calculations are presented which illustrate the effects of the shape and size of the secondary on the forces (lift and lateral) and the power factor. A levitation system for a 50 tonne MAGLEV vehicle is then investigated computationally.
