摘　　要：用三维有限元方法计算一台电励磁爪极发电机和一台新型混合励磁爪极发电机漏磁系数。爪极结构的特殊性决定了爪极发电机磁场呈三维分布,需用三维数值方法计算。采用有限元商用软件包通过前处理、加载和后处理等程序,得到电励磁爪极发电机和混合励磁爪极发电机不同结构参数下的空载漏磁系数,并总结出不同结构参数下漏磁系数的变化规律,对于不同类型爪极发电机的结构设计、磁场分析以及参数优化设计等方面的研究提供一定的理论参考。The magnetic leakage factors of two types of claw-pole alternators were computed using a three-dimensional （3-D） finite element（FE） method. The shape of the claws leads to a truly 3-D magnetic field in all regions. Consequently, for the correct calculation of magnetic field and alternator characteristics, a 3-D numerical method is required. On the basis of preprocession, solution and postprocession, the magnetic leakage factors of the alternators undei＂ no-load conditions in terms of different structure parameters were computed. Finally the results of variation trend of magnetic leakage factors were presented. The main conclusions are helpful to the structure design, magnetic leakage computation and to the optimal design of the claw-pole alternators
