摘　　要：细分技术作为一种提高步进电机步距分辨率的手段已被大量采用,步进电机采用细分驱动能提高分辨率,减少力矩波动,解决步进电机的低频共振问题,如何使步进电机的微步距角更均匀,一直是细分技术所研究的主要问题.该方法对由DSP实现反应式步进电机细分驱动的电流波形作了分析,实现了对步进电机的步距角细分控制.The subdivision has been generally used as a method to improve the differentiation of the step motor.The step motor can use subdivision to improve the differentiation, reduce the fluctuation of moment and resolve the problems of the resonance in low frequency.It is a main problem that how to make the step angle more even all the while. The current wave is analyzed for the subdivided step motor designed by using DSP, and the subdivision control of the step angle is realized.
