摘要:研究了航空电励磁同步发电机空载电压谐波产生的机理和降低发电机电压谐波分量的一些措施。以6极、54槽的电励磁同步发电机为例, 利用数值解析与二维有限元结合的方法分析了短距系数、分布系数以及定子斜槽对电励磁同步发电机空载电压的总谐波畸变率的影响,并在此基础上估算了一个最优斜槽角度来减少电压的总谐波畸变率。

Taking a electro-magnetic synchronous generator with six poles, fifty-for slot s as an example, analyzed the effect of pitching, distributing and skewing the winding on reducing the total harmonic distortion of phase voltage with no load. In the end, calculated the best angle of skewing to reduce the total harmonic distortion(THD).
