摘　　要：在单相串励电动机中,为了改善换向性能,采用将电刷逆转向偏离其几何中性线一个适当的角度。文中首先介绍准确确定换向器上的几何中性线的方法,在此基础上对气隙磁场作分解和波形简化处理,推导出旋转电势与偏移角的关系式,从而得出电刷偏移角的计算式。In order to improve commutating performance are taken to make brush to be offset reversal a suitable angle from geometric center line. lt first introdnces method of accurately determining geometric center line on commutator. on the basis of the method. airgap magnetic filed is resolved and waveform is simplified,relational expression between rotating po- tential and offset angle is also derived, then calculating formula of brush offset angle is gotten.
