建立了一个封闭的解析模型，建立了游标永磁电机比较的特殊规则。基于有限元分析（FEA），对Halbach、双定子（DS）和DS辐条阵列（DSSA）三种新型VPM拓扑结构的功率因数等关键参数进行了比较。分析模型和有限元模型的结果表明，DSSA电机具有最高的功率因数，即接近0.91，最高的转矩密度和最少的磁体使用量。
A closed-form analytical model is developed to build the special rules for vernier permanent magnet (VPM) machines comparison. Based on the finite element analysis (FEA), comparisons of some key parameters including power factor are made among three novel VPM topologies, i.e., Halbach, dual-stator (DS), and DS spoke-array (DSSA) structures. The results from both the analytical model and FEA model demonstrate that the DSSA VPM machine exhibits highest power factor, viz., similar to 0.91, highest torque density and fewest magnet usage.
