三绕组异步电机单相对称运行时的分析

Study on Symmetrical Operation of Three-Winding Induction Motors with Single-phase Source

讨论了三绕组异步电机在单相交流电源作用下，对称运行时所需裂相元件的最少数目并确定了元件的类型。根据电路基本理论与异步电机的等效电路，推导了元件参数的计算公式并从理论上说明了其对功率因数的改善。论文还提出了三绕组异步电机单相运行时要注意的几个问题。

The paper discusses how to determine the fewest numbers and types of splitting phase elements which are used in three-phase induction motors for symmetrical operation with single-phase source.Based on elementary circuit theory and equivalent circuits of induction motors,it deduces the formulas for calculating element parameters and theoretically shows that the power factor can be improved by means of splitting elements.Several problems which we must pay attention to about single-phase operation are also raised in the paper.
