多结果极无轴承电机可用于特定条件下的低速旋转和摆动阶段（或平台）。设计并制造了一种试验机，该试验机在径向x-y方向上主动控制两个自由轴。悬架绕组是一种新颖的环形，即它们绕在定子轭上。这产生了一个低轴向长度，因为线圈端是紧凑的。本文提出了一种多结果极转子的设计方法。设计过程考虑了泄漏通量和磁饱和，并在机器构造和测试之前使用了三维有限元分析。本文提出了一种新型的悬架绕组和转子结构。本文成功地实现了转子的悬浮，并提出了这些特点。
Multi-consequent-pole bearingless motors can be used in low speed rotating and swinging stages (or platforms) under specific conditions. A test machine has been designed and built and in this machine two axes of freedom are actively controlled in the radial x-y directions. The suspension windings are of a novel toroidal shape, i.e., they are wound around the stator yoke. This produces a low axial length because the coil ends are compact. In the paper, a multi-consequent-pole rotor design is presented. The design procedure considered the leakage fluxes and magnetic saturation and used a three dimensional finite element analysis before the machine was constructed and tested. This paper proposes a novel structure for the suspension windings and the rotor. The suspension of the rotor was found to be successfully achieved and these characteristics are put forward in the paper.
