无轴承驱动器和磁轴承允许无接触，无磨损和无润滑的旋转系统的建设。利用永磁体激励的转子盘允许通过磁阻力的三个自由度（倾斜和轴向偏转）的被动稳定。因此，使用这些无轴承薄片电机，可以设计非常紧凑的磁悬浮驱动系统。无轴承扇形电机是无轴承片式电机的一种，其定子由单个元件组成。事实上，所有这些定子段彼此磁性解耦。介绍了一种具有不同转子和定子组成的无轴承扇形电机的不同设计。特别是轴承力的产生的差异进行了概述。各种考虑驱动器的特殊功能进行检查，并讨论其优点和缺点。最后，通过不同的标准（如对电力电子设备的要求，被动刚度或轴承力和电机扭矩能力）对这些电机进行定性比较。
Bearingless drives and magnetic bearings allow the construction of contactless, wearless and lubrication-free rotating systems. Utilizing a permanent magnet excited rotor disc permits the passive stabilization of three degrees of freedom (tilting and axial deflection) by reluctance forces. Hence, using these bearingless slice motors it becomes possible to design very compact magnetically suspended drive systems. The bearingless segment motor is a subtype of the bearingless slice motor, where the stator consists of single elements. As a matter of fact, all these stator segments are magnetically decoupled from each other. This article introduces different designs of the announced bearingless segment motor featuring different rotor and stator compositions. Especially the differences in the generation of bearing forces are outlined. The special features of the various considered drives are examined and their advantages and drawbacks are discussed. Finally these motors are compared qualitatively by different criteria (like the demands on power electronics, passive stiffnesses or bearing force and motor torque capacity).
