摘　　要：介绍了几种不同结构的混合励磁爪极发电机的工作原理和磁场特点,包括串励式与并励式混合励磁等各种结构。通过分析它们各自的磁路与磁场分布特点,并将纯电励磁爪极发电机的输出能力与混合励磁爪极发电机的输出能力进行了对比分析,着重阐述了并励式混合励磁相对于电励磁与串励式励磁的优点。用三维有限元方法分析与计算了该结构电机的空载磁场及电感参数。The working principle and magnetic field characteristic of the hybrid excitation crow pole generator with different structure, which included with series, shunt type of hybrid excitation and etc., were introduced. Their magnetic circuit and field distribution characteristic were analyzed respectively while the analytical comparison of the output capability between those of the hybrid excitation crow pole generator and the pure electric excitation crow pole generator was done. Advantages of the hybrid shunt excitation against pure electric excitation and hybrid series excitation were described as keystone. The 3D finite element method was applied to analyze and calculate the noload magnetic field and induction parameter of the electric machine with this kind of structure.
