摘　　要：根据六相双丫移30°绕组的结构特点以及同步发电机与整流桥不同联接方式下电枢电流的实际波形,对其电枢磁势进行了系统的分析推导,得出了具有普遍意义的计算公式。在磁势分析的基础上,推导了六相同步发电机带整流负载时转子表面附加损耗的计算公式。并通过实例计算,对六相和三相的计算公式进行了比较分析,从而获得了一些具有工程实际使用价值的结论。In this paper, according to the structure of 6-phase Y-Y winding of 30 degrees phase displacement, and practical wave form of armature currents of synchronous generator connected to a rectifier bridge, the armature MMF of synchronous generator is analysed systematically.On the base of analysis of MMF, the formula for calculating additional losses of rotor surface is derived. The comparative analysis between 6-phase formula and 3-phase formula is made with example and some useful conclusions are obtained.
