摘　　要：为提供励磁同步电机的设计依据,提出了基于有限元电磁场计算软件分析其电气性能的方法。首先选取具有代表性的凸极三相4极励磁同步电机作为研究对象,构建其3D模型,设置各部分材料属性,生成线圈及设定电机初始位置,然后采取重点区域加密的自适应网格剖分方法,2D暂态求解器求解,最后采取Matlab完成数据的后处理,分析驱动电源的频率与电机转速、铜损、铁损、涡流损耗及磁场能量分布的关系,为电机设计人员提供技术支持。In order to provide design basis of the excitation synchronous motor, a new method based on finite element method（FEM） is proposed to analyze its electrical properties in this paper. First step is to select the representative excitation synchronous motor as studied object, to build a convex three- phase-four-polar 3D model, to set the material properties, to generate the corresponding coils and to set the initial position of the motor. Second step is to solve by the adaptive grid subdivision and 2D transient solver. Last step is to post-process data by Matlab to analyze the relationship between power frequency and motor speed, copper loss, iron loss, eddy current loss and magnetic field distribution, which provides the theoretic basic for motor designers.
