摘　　要：分析了混合式步进电动机的单步响应特性，阐明了电机单步运行时的轻重步机理，实例分析了五相混合式步进电动机４－５相通电运行时的单步响应特性，确定了轻重步的变换过程，指出了改善电机轻重步现象的相应措施．The phenomenon of light and heavy steps in hybrid stepping motors is presented based on an analysis of characteristics of the single-step operation. Focusing on the change of phase-current caused by 4-5 phases switching mode, the phenomenon in 5-phase hybrid stepping motors is investigated and a proposal to improve the phenomenon is presented.
