摘　　要：在考虑磁密谐波的情况下,推导出了发电机电动势的谐波绕组系数。通过优化线圈边宽度和极弧系数可以控制谐波绕组系数的大小,进而更加有效地在增大发电机输出电动势基波幅值的同时降低电动势的总谐波失真度。分析了极弧系数和线圈边宽度对磁密波形和电动势波形的影响,并利用响应曲面的方法寻求极弧系数与线圈边宽度配合的最优方案。最终,通过有限元结果验证了响应曲面方法在轴向磁通永磁电机优化设计中的可靠性。The winding factor with harmonic of electromotive force （EMF） of generators was deduced in the case of considering the flux density with harmonic. The winding factor with harmonic can be controlled by the optimization of the width of coil-side and pole-arc coefficient, then the amplitude of the fundamental harmonic of the EMF will be much higher while the total harmonic distortion （THD） of the EMF will be less lower. The effect of EMF waveforms and flux density waveforms produced by different pole-arc coefficients and different widths of coil-side was analyzed in the paper. The optimization scheme of the match between pole-arc coefficient and width of coil-side was searched by the response surface methodology. The reliability of the response surface methodology applied in axial flux permanent magnet machine was proved by finite element analysis （FEA） results.
