摘　　要：以三相感应式步进电机为研究对象,针对传统驱动控制中存在的振动和噪声严重的问题,引入了细分驱动的控制策略。详细给出了三相步进电机细分驱动的控制原理,并设计了细分驱动电路。细分驱动电路主要包括电流给定发生电路、电流采样电路、电流控制电路以及驱动电路等。所设计的细分驱动电路不仅可以应用到三相步进电机的驱动控制中,更可以推广到其它两相步进电机等的驱动控制中。Three phase induction stepping motor was studied, according to serious problems of vibration and noise using traditional control method, subdivided driving was introduced. Control theory of three phase induction stepping motor was presented and driving circuit was designed. The subdivided circuit contained current reference circuit, current sampling circuit, current control circuit, and driving circuit. The proposed subdivided driving circuit can not only be applied in three phase induction stepping motor control, but also other stepping motor like two phase stepping motor.
