摘要
用三相异步电动机三相绕组的星形旋转磁势图和行波方程证明了当供电相序不变时，电动机进行Ｙ形和两种△形绕组换接，无论起动或调速，其转向均不变。排除了有关Ｙ形变成不同△形时可能产生电源反接制动的疑问。
In this paper,the star-rotating-mmf drawings of three-phase-winding of three-phase-motor and travelling-wave-equation are used to prove that them3tor will turn in thesame direction when the three windings are arranged from star to delta or in reverse but the power phase order must not change。This gets over a wrong idea that the motor would turn in the opposite direction under this condition。
