摘要
介绍用两片集成电路组成的调频调压式步进电动机驱动电源。其特点是可使步进电动机高频输出转矩大、低频运动平稳、减弱低频共振、结构简单。
This paper introduces frequency modulation and voltage modulation controlling circuit for stepping motor constituted by two ICs. Its characteristic is to make big moment during HF, run smoothly during LF and to weaken LF resonance as well as constitution simple.
