新型双速变极电机及其优化设计的研究

A New Type of Two-Speed Pole-Changing Motor and the Study on its Optimum Design

本文介绍了一种新型低谐波含量,高性能的Y-△混接单绕组双速变极电机,分析了这类变极绕组的设计原理。并对这类电机的优化设计提出了一种新的优化方法──阶段转化SUMT法,实践证明,这个方法优于一般的罚函数法。另外,本文还讨论了初始可行点的寻求问题,提出了一种新的可行点求取方法,为开发新系列电机提供了新的途径。

In this Paper, a new type of star-defts connected two-speed pole-changing motor with single winding of low m. m. f-homonic contentS and high character is introdu ced, with the design principle of the kind of winding also being analysed in details,On design the electrical machine, a new optimum method-SUMT with stage coverting is provided, which is proved to be better than general punishing function. In addition, the problem of initial feasible point is also discussed and a new method, to get feasible point is proposed for exploring a new series of electrical machi ne.
