摘　　要：建立了五相混合式步进电动机恒频斩波恒总流驱动系统包括电流控制部分在内的单步响应特性的仿真模型,对单步响应特性进行了仿真。仿真结果表明新五边形接法、下桥臂斩波的五相混合式步进电动机4-5通电运行时的单步响应特性,存在着四步一循环的轻重步现象。对其进行的理论分析与仿真结果相符。A simulation model of five - phase hybrid stepper motor driver system with fixed - chopping frequency and constant total current driving are established, its one step response and the procedure of the light and heavy step phenomenon are analyzed. The simulation results prove that there exists the phenomenon of the light and heavy step in a cycle of every four step when a new pentagon connecting pattern and 4 - 5 phase excitation are used for 5 - phase hybrid stepper motor. The simulation results coincide with the theory analysis.
