针对传统双绕组磁悬浮开关磁阻电机绕组数量较多，电机结构复杂的特点，研究了一种8/6极单绕组磁悬浮开关磁阻电机，每个定子极上只有一套绕组且相互独立。分析了电机的运行机理和导通策略，基于等效磁路法推导了绕组自感和互感模型。为克服建模困难，提出了一种基于辅助函数的数学建模新方法，运用查表法建立了电机径向力和转矩的数学模型，大大提高了模型的实用性。用有限元分析验证了数学模型的准确性，为电机的进一步研究奠定了理论基础。

In view of the characteristics of traditional bearingless switched reluctance motors ( BSRMs ) which have too many windings and complex structure , a novel 8/6 structure BSRM which has single winding on a stator pole was analyzed , and every winding was independent of each other.The operation principle and the conduction policy were analyzed in this paper.The self inductance and mutual inductance of every wind-ing were deduced based on the method of equivalent magnetic circuit.A new method of mathematical model-ing based on an auxiliary function was proposed to overcome difficulties of mathematical modeling.The math-ematical models of radial force and torque were written based on the method of look-up table.The usefulness of mathematical models was improved greatly.The finite element analysis was carried out to verify the accura-cy of mathematical models , which provides the theoretical foundation for the further research of this motor.
