摘要
利用具有A/D转换功能和PWM输出功能的低成本单片机做控制核心,专业驱动芯片L6203做驱动电路,实现直流电机的转向、速度控制,同时为系统设计了转速显示电路,可实现闭环控制,并有较为可靠的过压、过流保护功能。
In this paper,a controller of DC motor is designed.This controller is based on MCU which has 8-channel A/D converter and PWM output unit.The driver of the DC motor is constituted by L6203.The system has a display unit of speed and a protection circuit of over-voltage and over-current.
