摘　　要：由于三相异步电动机定子绕组的联接方式不同，决定了断相后的磁势和机械特性的变化，本文通过理论指导，得出了在各种情况下的磁势表达式和对应的机械特性。The connective methods of the determinent in three non—synchronous motor are different, which lead to the changes of magnetic force and machine character after losing onephase. In this paper, we obtain the all formulations of the magnetic forces and the corresponding machine characters by theoretical deduction.
