化学、制药、生物技术和半导体行业的多种工艺需要通过密封的工艺室进行非接触式悬浮和旋转。这些应用的一个非常有趣的拓扑是“无轴承切片电机”概念，过去已经进行了一些研究，特别关注拓扑和实现问题。然而，在评估理想的电机相数方面只做了很少的工作。本文对两相和三相无轴承切片电机概念进行了性能评估。结果表明，三相系统可以提供与最先进的两相系统几乎相同的功率，并实现几乎相同的加速行为，尽管它们的电力电子工作要少得多。
Several processes in chemical, pharmaceutical, biotechnology and semiconductor industry require contactless levitation and rotation through a hermetically closed process chamber. A highly interesting topology for these applications is the “bearingless slice motor” concept, where already some research has been done in the past, especially focusing on topology and implementation issues. However, only little work has been done to evaluate the ideal number of motor phases. In this paper, a performance evaluation between 2-phase and 3-phase bearingless slice motor concepts is undertaken. It is shown, that 3-phase systems can supply almost the same power as state-of-the-art 2-phase systems and achieve nearly the same acceleration behavior, although they have significantly less power electronics effort.
