To deal with the coupling between the levitation force and torque, a new bearingless switched reluctance motor (BSRM) is presented in the paper, in which the torque flux is separated with the levitation flux. In addition, due to the low cost and power of the three-phase power converter, the radial levitation of the proposed BSRM is driven by a three-phase power converter. The structure of the proposed BSRM is first introduced. The mathematical models of radial levitation force are second established by employing equivalent magnetic circuit approach. Finally, the electromagnetic characteristics of the BSRM, such as flux field distribution, transient levitation force and force-current relationship are investigated through the MagNet 3D. The research results indicate that the novel structure has good performances.

一种新型无轴承开关磁阻电机的悬浮性能分析

为了解决悬浮力和扭矩之间的耦合问题,本文提出了一种新的无轴承开关磁阻电机(BSRM),其中扭矩磁通与悬浮磁通分离。此外,由于三相电源转换器的成本和功率较低,所提出的 BSRM 的径向悬浮由三相电源转换器驱动。首先介绍所提出的 BSRM 的结构。其次采用等效磁路法建立径向悬浮力的数学模型。最后,通过 MagNet 3D 研究了 BSRM 的电磁特性,例如通量场分布、瞬态悬浮力和力-电流关系。研究结果表明,该新型结构具有良好的性能。
