摘　　要：主要提出了新型多星型移相变极电机定子绕组附加环流损耗的实用计算方法,分析了定子绕组支路不平衡时支路电流的分布情况,计算了样机定子绕组附加环流损耗,并与实验结果相比,证明计算方法的正确性。同时研究了负载及支路不平衡度大小对定子绕组附加环流损耗的影响,得到有益的结论。In this paper, a practical method to calculate extra circulation losses in novel multi-star phase shafted (MPS) pole changing windi ngs was presented, the distribution of currents in unequilibrium parallel branch was analyzed, and This calculation method proved correct by contrasting the exp erimental with calculation data of a modal machine. At the same time,the influe nces of the size of loads and the degree of unequilibrium among branches on extr a circulation losses in stator windings was studied, and some useful conclusion was gotten.
