摘　　要：研究了楞次定律及法拉第电磁感应定律在电机原理分析中容易引起理解错误的原因,提出采用感生电压代替感生电动势来分析电机原理的方法,并应用该方法分析了变压器负载运行时各个变量之间的关系,给出电压、电流平衡方程、等效电路及相量图。Firstly, the reason that Lenz＇s law and Faraday＇s law of electromagnetic induction may cause wrong understanding in motor principle analysis is researched. Secondly, a new analysis method is put forward that adopts induced voltage to replace induced electromotive force in motor principle analysis. Lastly, with the given voltage, current balance equation, equivalent circuit and phasor diagram, this method is applied to analyzing the model of transformer in load running and the relationships among various variables.
