比较了开关磁阻电机(SRM)与2009款丰田普锐斯(Prius)采用的稀土永磁电机相比，具有相当的转矩密度和效率的最大转矩。开关磁阻电机在短时间内提供最大扭矩的饱和程度很高，因此，由于材料设置的不完善，即使在三维有限元分析中，扭矩值也往往与实验结果有相当大的误差，达到15%。文中还对磁链和电流进行了比较，以供参考。文中给出了二维有限元和三维有限元分析的结果，以及试验机的计算结果。三维有限元分析中的最大扭矩相对于试验机的最大扭矩误差在5.0%以内。
The maximum torque values in computer analysis and experiment in the switched reluctance motor (SRM), having competitive torque density and efficiency with respect to the rare-earth permanent magnet motor employed in the 2009 Toyota Prius, have been compared. The SRM is highly saturated to provide the maximum torque for a short time; thus, the torque value tends to have considerable error of 15% even in the 3D FEM analysis with respect to experimental result because of the incomplete material setting. A comparison of the flux-linkage and current is also provided for consideration. The results of the 2D-FEM and 3D-FEM analysis as well as a test machine are presented. The maximum torque in the 3D-FEM analysis is shown to be within errors of 5.0% with respect to that in the test machine.
