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.
