摘要
以STC89C52单片机作为控制器,采用L298N芯片作为电机控制芯片,选用S177霍尔元件传感器,并用T测量法,设计了直流电机控制和速度检测系统。该系统能对电机的转速和转向进行实时控制,能同步显示电机转速与转向。系统具有控制灵敏,速度检测准确,电路简单易行的特点。
A DC motor control and speed detection system is designed using T measurement with STC89C52 as a single-chip controller, L298N chip as a motor control chip and a S177 Hall element sensor. The system can real-time control the motor speed and direction, and simultaneously display the motor speed and steering. This system has features of sensitive control, accurate speed detection and the simple circuit structure.
