摘要
本文研究了三相变极调速异步电动机不断电切换绕组的设计原理，所研究的绕组均只有六个出线头，控制方法非常简单，提高了变速不断电切换的可靠性，降低了变速切换的成本。
The design principle of pole\|changing windings without interruption of power supply for three\|phase induction motor is studied in this paper. All the windings studied have six terminals. The method of controlling speed\|changing switchover is very simple, and the reliability of speed\|changing switchover is improved while the cost of switch of pole\|changing windings is decreased.
