摘　　要：在各种关于电机学的教材中,变压器、直流电动机、异步电动机、无阻尼绕组凸极同步电机这四大类电机的稳态电动势方程式部是根据合成磁场理沦的推导而来,而动态过程则适合采用电工理论中的耦合电路方法进行分析。实际上通过耦合电路法同样可以推导出上述四类电机的电动势平衡方程。详解了推导过程,所得到的结果与用合成磁场建立的电压方程一致。The electromotive force equation in static state of transformer, DC motor, asynchronous motor and synchronous motor without damping windings are deduced by theory of composite magnetic field in all kinds of teaching material, but the dynamic state should be analyzed by means of the coupling circuit method. In fact it can also be used to deduce electromotive force equations of these electric machineries. The paper presents the deductive process of synchronous motor＇s electromotive force equation in statics tate, The results conforms that the voltage equation is as same as that of composite magnetic field method.
