【摘要】 阐明了五相混合式恒频斩波恒总流步进电动机系统仿真的主要问题，对斩波过程主电路拓扑结构变化作了细致分析，建立了完整的系统仿真模型。仿真结果与实测基本一致，说明模型是可靠的。更多还原

【Abstract】 This paper described the basic and important things in the simulation of the 5-phase hybrid stepping motor system with fixed total-current driver.This paper analysed the changes of circuit-topology in detals,and given out the system’s simulation model. The simulation results coincide well with the actual ones,so we can see the model is correct.更多还原
