摘　　要：直流电动机结构简单,工作稳定可靠,较易实现伺服控制。本文以PIC16F1508单片机为控制器,运用其PWM模块和CWG模块产生带死区的互补PWM波形,输入给H桥驱动的上下桥臂,有效解决了直流电动机H桥驱动上下桥臂的直通问题。并对90ZYT55直流电动机进行实验,取得了较好的实验成果。The DC motor has the advantages of simple structure and reliable work,and it easy to realize servo control.This article takes PIC1 6F1 508 as the control processor,which uses PWM and CWG modules to produce the complementary PWM waveforms with dead zone.The waveforms access to H-bridge,which effectively solves the H-bridge upper and lower leg straight.The experiment shows that the DC motor 90ZYT55 achieves good results.
