摘　　要：分析设计两种具有结构简单、转矩密度高等优点的新型三相永磁开关磁链电机,并利用二维有限元软件分析电机几何形状对反电动势波形、齿槽定位转矩和径向不平衡力等因素的影响,并以此为基础进行优化设计。Two novel 3 - phase PM flux switching motors, which have simple structures and high torque density, are designed and compared in this paper. Furthermore, their geometrical design variables are analyzed, using 2 - D finite element method, so that their influence on the motor performance, such as the back - EMF waveform and harmonics ,the cogging torque and the unbalanced radial force, is inspected, and the design variables are optimized.
