转速测量是实现电动机控制的重要步骤之一。基于传统的测量直流电动机转速的方法中[1]存在着测量不精确，有的设备成本较高等问题，为了能够更精确的进行转速测量反映直流电动机调速系统的速度[1]，本文采用可编程控制器PLC进行电动机电压电流信号的采集计算，通过实际的实验测试，测量直流电动机的转速，并与已有的一些测速方法进行分析比较。得到了应用直流电动机的电压和电流得到的测量转速方法能更好的反映直流电动机的转速，便于实现电动机的控制。

The speed measurement is one of important steps in the motor control .Based on the fact that the inaccuracy of DC motor speed measurement and some equipments’ high expense we make a new method to measure the speed of speed regulation system. This article adopts PLC controller to get voltage and current signals and calculate them. Through the practical lab, we can get the DC motor speed. Compared with other methods, we can get that this method has better effect than others and easily to control.
