比较了带有和不带有被动磁力轴承 (PMB) 的无轴承电机。无轴承电机在两个垂直的 x-y 轴上受到主动控制。轴向和圆锥运动由 PMB 支持。将实验结果与三维有限元方法的计算结果进行了比较。 PMB 的有效性在静态和动态测试中进行了分析和实验研究。结果发现，只有 PMB 的旋转测试才能成功。
Performance comparisons in a bearingless motor with and without passive magnetic bearings (PMBs) are presented. The bearingless motor is actively controlled in two perpendicular x-y axes. The axial and conical movements are supported by PMBs. The experimental results are compared to the calculated ones by 3-D finite-element method. Effectiveness of PMBs is analytically and experimentally investigated in both static and dynamic tests. It is found that a rotational test is successful only with the PMBs.
