对于低速应用，如旋转和摆动阶段，多顺极无轴承电机提出。本文介绍了多顺极无轴承电机的基本特性。与传统的无轴承电机不同，在后极型上产生的悬浮力与转子的旋转位置无关。因此，多极转子如40、44和46极是容易的，而在旋转角位置检测中没有高精度的损失。从悬浮力和平均转矩能力两个方面讨论了极数选择的基本设计。采用多极转子结构可以减小磁力误差。一个测试机已被构造和驱动的紧凑型驱动器和CPU单元。
For low speed applications, such as rotating and swing stages, a multi-consequent-pole bearingless motor is proposed. This paper describes basic characteristics of a multi-consequent-pole bearingless motor. Unlike conventional bearingless motors, suspension force generating on consequent-pole type is independent of rotor rotational position. Thus, multi-pole rotors such as 40, 44, and 46 poles are easy without a penalty of high precision in rotating angular position detection. Basic design of pole number selection is discussed with suspension force and average torque capability. Magnetic force error can be reduced with multi-pole rotor configuration. A test machine has been constructed and driven by a compact drive and a CPU unit.
