摘　　要：】研究了五相混合式步进电动机４—５相通电运行时的轻重步现象，通过分析不同通电方式时导通与截止相的相电压变化对相电流的影响，阐明了３—４相通电方式可以改善电机轻重步现象的机理，并进行了实验验证。The phenomenon of light and heavy steps in 5 phase hybrid stepping motors is investigated.Focusing on the relationships between phase current and phase voltage caused by different switching modes,a proposal to improve the light and heavy steps under 3 4 phase mode is presented and the well agreed experimental results are given.
