摘 要
直流电机产品是工业自动化,家庭现代化等各个领域广泛应用不可缺少的基础产品。与其它类型的电机相比,直流电机具有调整平滑、调速范围广、过载能力大、热动和制动转矩较大等优良的特性,因此直流电机在起动和调速要求较高的生产机械上广泛地被应用。对直流电机的速度调节,可以采用多种办法,本文在直流电机调整和PWM实现方法的基础上,提供一种用单片机产生PWM脉冲实现调速的方法,可控制直流电机平稳的运转,满足工业自动化控制的许多特殊要求。
本设计以MCS-51单片机为核心,以4×4矩阵键盘做为输入对直流电机进行控制,通过对占空比的计算达到精确调速的目的,来控制直流电机的启停、速度和方向。该系统电路简单,工作可靠,符合直流电机驱动的基本要求

Abstract
  DC motor products, industrial automation and modernization of the family, and other fields wider application of the indispensable foundation products. And compared to other types of motors, motor with smooth adjustment, the governor broad in scope, Guozainengli large, dynamic and thermal brake torque characteristics of the larger, and so fine, so the starter motor and high speed requirements Production machinery to be used widely. The DC motor speed regulation, can use a variety of ways, this adjustment in the DC motor and PWM method on the basis of a microcontroller used to provide a PWM pulse of the methods to achieve speed, can control the smooth functioning of DC motor, Industrial automation and control to meet the many special requirements.
  The design MCS-51 microcontroller as the core, 4 × 4 matrix keyboard input as the DC motor control, through the calculation of the duty cycle to achieve the purpose of precise speed control, to control the motor of Com
