摘　　要：介绍了基于电流矢量恒幅均匀旋转的步进电机细分驱动原理。采用电流跟踪型PWM控制方式,给出了一种三相混合式步进电机驱动器的硬件和软件设计方案。实验结果表明,输出相电流接近正弦波,电机运行平稳。This paper introduces subdivided driving principle of stepping motor based on constant amplitude of current vector rotate evenly. Hardware and software design of the three-phase hybrid stepping motor driver is presented,applying current tracking PWM control mode. The experiment results show that the phase current is similar to sine wave and motor operate steadily.
