电动机定子三相绕组的首尾判别

Analysis on initial-and-ending distinction of electric motor's three-phase stator winding

正确判别和连接电动机定子三相绕组的首尾 ,是电动机正常工作的保障。在介绍首尾判别方法的基础上 ,着重从定子各相绕组在空间相差 12 0°的角度 。

It can exactly judge electric motor a normal work to distinguish and link up initial and ending of electric motor's three-phase stator .This paper aimes at the character of higher vocational students and focuses on analyzing the distinction principle, based on the presentation of initial-and-ending distinction, through such an angle as 120° from which each stator winding is apart in the space.
