摘　　要：介绍基于AT89C51为核心实现的三相混合式步进电动机系统。系统采用电流跟踪PWM方式使混合式步进电动机的各相绕组电流接近正弦波,从而在电机内部形成了幅值基本不变的圆形磁场,既可提高混合式步进电动机的分辨率,又能解决低频振荡问题。A control system of three-phase hybrid stepping motor based on AT89C51 is introduced in this paper. With current tracing PWM method, the current of three-phase windings were controlled to close sine-wave, thus round magnetic-field with approximate constant amplitude in the electrical machine can be formed. By this method, resolution ratio of hybrid stepping motor can be improved and the problem of low-frequency vibration can be solved.
