摘　　要：通过合理选择步进电机细分电流波形和驱动芯片,提出并介绍了单片机控制的细分恒流步进电机驱动方案及实现技术。实验结果表明,系统的低、高频性能和起动性能有了明显的提高。Through the reasonable selection of division electric current waveform of phase winding for stepper motor and motor drive IC, it presents and introduces the motor drive scheme of constant current and division based on microcomputer and the relative technique. As the experiential results show, systemic performance of stepping motor starting and operation in high or low frequency are improved.
