摘　　要：对二相混合式步进电动机的微步驱动方式提出了不同于传统的新分类,着重研究了电流追踪型的几种驱动方式。汲取电流滞环控制及固定开关频率控制的优点,提出恒频脉宽调制型微步驱动方式,解决了检测电流波形必须完整的问题。仿真及实验结果验证了这种驱动方式的可行性及有效性。This paper presents the new classification of subdivided driving methods of 2-phase hybrid stepping motor. Some driving methods about tracking current control are studied chiefly here. Learning from the current lagging-loop control and invariable switch frequency control, pulse width modulation driving method is suggested. This method solves the problem of noncomplete current sampling wave. Pspice simulation and testing results verified the validity and the feasibility of the driving methods.
