目前,已经有许多种控制直流电机转速的方法。这些方法虽有各自的优缺点,但它们有一个共同缺点:不适合于计算机控制且使用不方便。本文提出了一种新的控制电机转速的方法,即利用计算机输出信
Currently, there are many ways to control the DC motor speed. Although these methods have their own advantages and disadvantages, they have one common disadvantage: not suitable for computer control and inconvenient to use. This paper presents a new method of controlling the motor speed, the use of computer output signal
