摘要
为了补偿 0°/360°/0°线捧端部漏磁场的影响,本文对这种线棒在槽部设置一处及三处空换位进行了理论分析,导出了计算其空换位长度及相应环流附加损耗比值的解析式,供设计及改造大型交流电机定子线棒时参考。
In order to compensate the effect of end leakage field produced by the current in the0°/360°/0°bar itself,the authors have carried out theoretical analysis for 360° transposition bar with one void and three voids in slot portion.Thus the analytical ex- pressions for calculating the length of voids and its circulating Current loss ratio have been deduced.
