变后极为3倍数时的反向法变极非正规绕组的排列

Design of Unconventional 2-Speed Windings for Induction Motors with a Triple Multiple Pole Number using Reversing Coil Techniques

本论文提出了一种反向法变极绕组的系统设计方法和最小对称槽号组的概念。利用这个系统设计法和最小槽号组的概念,对任意极比的反向法非正规变极绕组的设计,可预先判定对称方案是否存在,如存在的话,可保证所得到的绕组方案均为对称方案而无须任何试探。论文最后用实例说明了上述方法及概念的运用。

This paper proposes a systematic method in the design of pole-changing windings based on reversing coil techniques and the concept 'the minimum symmetric coil groups'. Using the method and the concept can judge whether symmetric pole-changing winding layouts exist before pole-changing windings with any pole ratio are designed and can ensure that the layouts obained is symmetric if there exist symmetric pole-changing winding layouts. Finally, applications of the method and the concept are illustrated by examples.
