轻载电动机改延边三角形结线运行的节电分析

Power-Saving Analysis on Light load Motor with Lengthening Triangle Winding Connection

本文通过对电动机两种改接方式下效率和功率因数的计算、对比，得出延边三角形（A）联结比星形（Y）联结更节电。

This paper Compares motor efficiency andpower factor by analysing two winding connection of motor and then proposes that Lengthening trangle windingis better than star winding form the viewpoint of power-saving.
