随着原材料成本的飙升，对运行速度更快的小型驱动器的需求不断增加。与此同时，磁性轴承和无轴承驱动器已经超出了纯粹的学术水平，是几个工业过程的最先进解决方案。工业上所有的无轴承驱动器和大多数学术研究中的无轴承驱动器都以相对较低的速度运行，最高可达15,000 r/min。因此，是否适合高速运行仍不清楚。随着对无轴承驱动器的简要介绍，高速运行的标准和这种拓扑的能力，以满足他们在第一部分进行了讨论。第二部分给出了一个原型系统的描述，设计达到超过100,000 r/min的速度。最后一节给出了样机运行性能的实验结果。
With soaring raw material costs, the need for smaller drives running at higher speeds is ever increasing. In parallel, magnetic bearings and bearingless drives have outgrown the purely academic level and are the state of the art solution for several industrial processes. All the bearingless drives in industry and most of them in academic research run at relatively low speeds of up to 15 000 r/min. Thus, the suitability for high speed operation remained unclear. Along with a brief introduction to bearingless drives, the criteria for high speed operation and the ability of this topology to fulfill them is discussed in the first part. The second part gives a description of a prototype system, designed to reach speeds of beyond 100 000 r/min. The last section shows the experimental results of the prototype concerning the operational behavior.
