变极电机绕组设计的“双极对数槽号相位图”

A Twin Pole-pairs Slot-number Phase Diagram for the Design of Pole-changing Windings

论述了交流电机变极绕组设计理论中的一种新工具──双极对数槽号相位图的概念、原理、画法及基本特点。应用双极对数槽号相位图设计变极绕组时，可同时直观地观察同一绕组方案在两种不同极对数下的分布情况，兼顾两种极对数下的绕织性能，直接得出对两种极对数均具有优良性能的绕组方案，并可定性分析在各种变极绕组连接方式下方案的可行性。通过一个设计实例简要说明了此种相位图的具体应用。

The concept,principle,layout technique and basic features of new type of a “twinpole-palrs slot-number phase diagram”are described. The application of the diagram in thedesign of pole-changing windings is illustrated with a practical example. It can be seen thatthe distribution of the same widning under two different pole-pair numbers can be directlyperceived at the same time and so a feasible design with better performance can be foundquickly and easily。
