矩阵模式归纳法在变极绕组设计中的应用

Application of Inductive Method of Matrix Model to Pole-Changing Windings Design

本文提出了采用矩阵模式归纳法来排列变极变速电动机的绕组,从而使绕组的分布系数有明显的改善,即接近于或达到了相应的单速电动机的水平。还利用槽电角度的规律性找出了削弱或消除多路绕组间的电势不平衡性的新途径。

In this paper, an inductive method to arrange the coil numbers of the polechanging varying speed motor into the matrix model is developed, therefore, which let the spread factor improved obviously——come near to or reach that of the single speed motor. The new way to reduce or eliminate the unbalancedness of the induced emf among the multi-circuit windings is found out by use of the regularity of the slot electric angular degrees.
