为了实现磁悬浮开关磁阻电机(BSRM)转矩和悬浮力的自然解耦,提出了一种新型混合励磁磁悬浮开关磁阻电机(HEBSRM)。新型HEBSRM由12/14极BSRM、 环形永磁体和径向磁轴承三部分组成。12/14极BSRM的转矩极和悬浮极之间嵌有隔磁环,使转矩磁通路径完全独立于悬浮磁通路径,从而在结构上实现转矩与悬浮力解耦。此外,详细推导了电机径向悬浮力的数学模型,并且通过有限元分析验证了新型HEBSRM结构的合理性。

[Abstract]
In order to realize the natural decoupling of the torque and suspending force of a bearingless switched reluctance motor (BSRM), a novel hybrid excitation bearingless switched reluctance motor (HEBSRM) was proposed. The new motor consists of a 12/14 BSRM, an annular permanent magnet and a radial magnetic bearing. The torque flux path was completely independent of the suspending force flux path, and the decoupling of torque and suspending force was realized in the structure. In addition, the mathematical model of the radial suspending force of the motor was deduced in detail and the rationality of the structure was verified by the finite element analysis.
