摘要
通过计算每一定子极面下的磁通量,建立磁悬浮开关磁阻电机径向力数学模型,该模型考虑了偏心位移对径向两个自由度径向力的耦合影响与漏磁通的影响。以一台样机为例,开展有限元仿真试验,仿真结果证明了该数学模型的正确性与有效性,为电机的悬浮控制系统设计提供了可靠的理论基础。
In this paper, the radial force mathematical models were built by calculating magnetic flux through every stator pole, which considered the rotor eccentricity and coupling between the two degrees of freedom radial forces. By the finite element simulation on the prototype, the proposed mathematical models were proved correct and valid.
