本文介绍了一类新型的无轴承薄片电机的第一个原型，其主要区别于其他例子，这种电机拓扑结构是在转子中的永磁体的情况下。一个单极永磁偏置气隙场产生的定子磁铁，并使被动稳定的三个自由度。这种驱动器概念具有特殊的操作行为，使其区别于其他最先进的无轴承驱动器。一个原型电机进行了优化和制造，并进行测量，以验证有限元模拟结果，并证明驱动器的功能和非线性控制方案。
This paper presents the first prototype of a novel class of bearingless slice motors whose main difference from other examples of this motor topology is the absence of permanent magnets in the rotor. A homopolar permanent-magnetic-bias air-gap field is generated by stator magnets and enables passive stabilization of three degrees of freedom. This drive concept features special operational behaviors that distinguish it from other state-of-the-art bearingless drives. A prototype motor was optimized and fabricated, and measurements were conducted to verify finite-element simulation results and to prove the functionality of the drive and its nonlinear control scheme.
