【摘要】 通讨对变极凸极同步电机气隙磁导谐波磁场及其定子各支路绕组的分析，从理论上证明了该类电机气隙磁场中存在很强的分数次谐波分量．这种谐波将会在有并联支路的定子绕组中产生环流。更多还原

【Abstract】 By analyzing permeance harmonic magntic field in air gap of pole-changing salient pole synchronous machine and branches of stator winding, it is theoretically proved that there are very strong fractional harmonic component in air gap magnetic field of this machine, and this harmonics can generate cirulating current in parallel branches of stator winding.更多还原
