摘要

定子开槽增加了等效气隙正如弗雷德里克·威廉·卡特在1901年指出的那样。此后，卡特因子为解析计算电机开槽下磁通密度下降的问题提供了一种解决方案。目前，半磁楔（smw）常用于关闭定子槽和平滑转子表面的磁通密度行为。smw还部分补偿了开槽引起的磁通量下降，使得等效气隙长度比没有smw的情况下短。但是，原来的卡特因素没有考虑到中小武器的影响，因此应该加以扩大。本研究提供了一种扩展原始Carter因子来计算smw存在时的等效槽开度的解决方案。

Extending Carter Factor to Slot Openings Equipped With Semimagnetic Slot Wedges

Stator slotting increases the equivalent air gap as Frederick William Carter pointed out already in 1901. Since then, the Carter factor has provided a solution to the problem of analytically calculating the decrease in magnetic flux density under an electrical machine slot opening. Nowadays, semimagnetic wedges (SMWs) are often used to close the stator slots and to smooth the flux density behavior on the rotor surface. SMWs also partly compensate for the slotting-caused decrease in the magnetic flux making the equivalent air gap length shorter than in the case without SMWs. However, the original Carter factor does not take into account the effect of SMWs and should, therefore, be extended. This study offers a solution for extending the original Carter factor to calculate the equivalent slot opening in the presence of SMWs.
