摘　　要：对于某些槽数和极数比的多星形移相变极电机 ,提出与前人不同的是在两种极数下均不甩去线圈的绕组方案 ,使绕组利用率高 ,且线圈及其联接都较简单。这种绕组方案在一种极数下并联支路略有不平衡 ,其所引起的电机定子铜耗的增加是极其有限的 。The difference from the previous paper is that the winding schemes suggested here have no coils left under either pole for motors with certain slots and ratio pole changing in the multi star connection for phase shifted pole changing windings.These schemes have higher utility and simpler coils connection but follow with slight unequilibrium among parallel path under one pole case.The increase of the copper loss of stator is certified and it is not high enough to affect the effective operation of the tested motor in the case.
