摘要：基于有限元法定量研究每相串联匝数、永磁体厚度、定子直径、气隙长度和槽宽对永磁发电机电压调整率的影响规律。结果表明，电压调整率随每相串联匝数、气隙长度的增加而升高，随永磁体厚度、定子直径、槽宽的增加而降低，但随永磁体厚度增加变化并不明显。归纳总结得出减少每相串联匝数、增加定子直径、缩短气隙长度、加大槽宽是降低电压调整率的有效方法。

Abstract: The influence of some parameters of the permanent magnet generator voltage regulation was analyzed based on the finite element method, which included turns in series per phase, thickness of the permanent magnet, stator diameter, air gap length, slot width. The results shows that, the voltage regulation rises with the increase of the turns in series per phase, air gap length and decreases with the increment of the thickness of permanent magnet, stator diameter and slot width. But the change is not obvious with increasing thickness of the permanent magnet. In summary, it is an effective method to reduce the voltage regulation by decreasing the turns in series per phase, increasing stator diameter, decreasing air gap length or increasing slot width.
