摘要
介绍单片机在直流电机转速控制系统中的应用优势及硬件、软件的实现方法。系统采用霍尔元器件测量电动机的转速,用89C51单片机对直流电机的转速进行控制,用DAC0832芯片实现输出模拟电压值来控制直流电动机的转速。
The paper presents application of one - chip computer in the speed control system of DC motor and realizing mothed of hardware and software. The system adopts Hall sensor to measure the motor speed ,tous 89C51 one - chip computer to control the speed of DC motor and to use DAC0832 chip achieve output analog voltage value to control the speed of DC motor.
