基于单片机的直流电动机测控系统设计

Design of Measurement and Control System of a DC Motor Based on SCM

介绍了一种基于单片机的直流电机测控系统.采用单片机构成的直流电动机测控系统,其测控系统核心主要由单片机、键盘功能模块、显示模块、电机驱动电路、直流电机等组成,系统采用PWM技术对电机进行控制,通过对占空比的计算达到精确调速的目的.

An observation and control system based on SCM（single-chip microcontroller）is designed.The measurement and control system of the DC motor based on SCM is consist of single-chip microcontroller constitutes,which is the core in the system,keyboard function module,demonstration module,motor-driven electric circuit,direct current machine and so on.The PWM（Pulse Width Modulation） technology is adopted to carry on the control to the electrical machinery in the research and the precise velocity modulation is achieved through the computation of duty factor.
