摘　　要：首先用变网络等效磁路法计算了 12 / 8结构的某双凸极交流发电机的空载相电压 ,给出了实验结果的对比。然后 ,在此基础上给出了双凸极无刷直流发电机的空载特性的求法 ,计算的结果和实验的结果进行了比较 ,说明该方法具有较高的计算精度。Firstly, phase voltage of a 12/8doubly salient AC generator without load is computed with the variable network equivalent magnetic circuit method and the experimental result is also given. Based on this, the method of how to compute the open-load characteristics of doubly salient brushless generator is shown. The computation results are verified high accuracy with the comparison th experimental results. The open-load characteristics of this brushless generator offer an important theoretic underground for the magnetic design of this generator.
