摘要：传统的直流电机调速大多采用电阻压降、双极性管和晶闸管驱动的方法,但是效率较低,不够稳定。本文介绍了由开关电源供电、大功率VMOS管驱动、脉宽调制的直流电机无级调速系统的设计,分析了系统的工作原理,实现了无触点、高效率、稳定的正反转调速。
Most of today＇ s traditional DC-motor speed regulation systems are driven by resistzmce, bipolar and thyratron, which have deficiency in stability and efficiency. To solve these problems, this article have introduced a design of the DC-motor speed regulation system for the conveyor line powered by Multi-Output switching power, driven by power field effect transistor （VMOS） and controlled by PWM driver program which would realize the non-contact positive and negative rotation control. Having analysed the principle of this system, we have implement the non-contact positive and negative rotation control stably and efficiently.
