摘　　要：本文提出了5相混合式步进电动机的组合励磁方法,它可在不改变驱动硬件及电机结构的情况下得到更小的步距角。通过0.18°步距角的实例,详细介绍了力矩矢量图和绕组励磁序列。对42PZ-203电机的严格试验,证明了组合励磁细分原理的正确性和实用性。与加工中心机床的联机试验结果表明,本方法在减轻与避开低频振荡及提高拖动系统整体性能方面具有明显效果。This paper presents a new principle of ministepping for 5 phases hybrid stepping motor (SM),called synthetic excitive ministepping,It can be used for realizing ministep of SM and needs not to rebuild motor and drive system. The diagram of electric-magnetic moment and exciting sequence of stator have been explored. By means of the testing of SM model 42PZ and the operating of a machining center. equipped with SM 42 PZ, the effectivity and the advantage of the principle have been veri fied.
