摘　　要：采用三维有限元方法对一台爪极发电机的电枢反应进行了研究。基于ANSOFT软件对电机气隙磁场和电感矩阵进行了计算仿真,通过对电感矩阵进行派克变换,进而得到交、直轴的电枢反应电抗。所得结果与用相量图方法计算的结果进行了比较,证明了解的正确性与可行性,为爪极发电机的优化设计奠定了理论基础。The armature reaction of a claw-pole alternator using three dimensional finite element method was analyzed. Air-gap magnetic fields and inductance matrix were calculated by Ansoft. The quadrature-axis and direct-axis armature reaction reactance were obtained through the Park transformation. The results between this method and phasor diagram method were compared and verified. Its validity and feasibility were indicated, which was the theorctic foundation for the optimum design of claw-pole alternators.
