本文提出了一种新型的分励磁绕组变磁通电机。为了降低弱化电流引起的铜耗，特别是在高速条件下，在电机转子中加入了励磁绕组。除此之外，还使用电刷和滑环为励磁线圈供电。采用有限元方法对弱化电流损耗进行了计算，以评估该电机的降损效果。并将计算结果与实验结果进行了对比，验证了分析的准确性。
This paper presents a novel variable flux motor with separately excited field winding. To reduce the copper loss caused by weakening current especially in high speed condition, field winding is included in rotor of the proposed motor. In addition to that, brush and slip ring are used for electric power supply to field coil. To estimate the loss reduction of the proposed motor, weakening current loss is calculated by using finite element method. Moreover validate of the analysis accuracy is confirmed with comparison results between calculation and experimental results.
