摘　　要：给出了一种基于LabVIEW的无传感器直流电动机测速方法,仅配备了一块PCI-6221的数据采集卡,通过LabVIEW图形化的编程,在计算机屏幕上显示转速,制作十分简便。与普通离心式转速表对照,大部分速度区域误差小于3%,在低速区域误差小于5%。A sensorless speed measurement system of DC motor based on LabVIEWwas proposed. Only a National Instruments PCI-6221 data acquisition card is needed, with graphic programming by LabVIEW, the rotation speed of a DC motor can be measured and its data can be displayed on the PC screen. Compared with the general centrifugal tachometer, the error is less than 3 percent except in lower speed range.
