摘　　要：定子端部漏感是定子漏感参数的重要组成部分,准确的端部漏感计算是电机过渡过程分析和高性能电机控制的关键。利用能量法、Boit-Savart定律、矢量磁位法对喇叭口形、半椭圆形以及半矩形绕组端部漏感进行计算,并与试验测试结果对比,分析得到不同形状端部漏感最合适的计算方法。分析结果表明,喇叭口形绕组端部漏感宜采用矢量磁位法计算,半椭圆形绕组端部漏感宜采用能量法计算,半矩形绕组端部漏感宜采用Boit-Savart法或矢量磁位法计算。Stator end leakage inductance is an important part of stator leakage inductance parameters.Accurate calculation of end leakage inductance is the key to motor transition process analysis and high performance motor control.Based on the energy method,Boit-Savart law and vector magnetic potential method,the leakage inductance parameters of horn mouth winding end,semi-elliptic winding end and semi-rectangular winding end are calculated.Compared with the test results,the most suitable calculation method of end leakage inductance for different winding end shapes is obtained.The analysis results show that the end leakage inductance of horn mouth winding end should be calculated by the vector magnetic potential method,the semi-elliptic winding end by the energy method,and the semi-rectangular winding end by the Boit-Savart method or the vector magnetic potential method.
