本文对分数槽感应电机的设计进行了研究。分析模型用于确定定子槽、转子槽和磁极对的最佳组合。在定子和转子中都考虑了多层绕组(两层以上)，以减小磁势空间谐波幅值，从而限制转矩脉动。给出了多层绕组的一般设计步骤，并给出了应用实例。由于采用了多层绕组，大大降低了转矩脉动。文中给出了两个样机的预测结果和实验结果。
This paper considers the design of fractional-slot induction machine. An analytical model is used to identify the best combinations of stator slots, rotor slots and pole pairs. Multi-layer windings (with more than two layers) are considered in both the stator and the rotor to reduce the MMF space-harmonics amplitudes and so to limit the torque ripple. After the general design procedure for the multi-layer windings, an application example is presented. Thanks to the adoption of multi-layer windings, a considerable reduction of the torque ripple is achieved. Both predictions and experimental tests on two prototypes are included in the paper.
