Motor protector is a complex product and has powerful protection function. It has high accuracy and wide range re-quirements for current regulating. It was constructed by combining coarse and fine voltage regulators to form wide range and high accu-racy alternating constant-current source. The software was programmed by using LabVIEW software to realize data acquisition,process-ing,real display and real control. The auto testing device based on virtual instrument was constructed with data acquisition card,con-trol system and drive circuit. Practical application shows that the system has solved the shortcomings of traditional test method of low accuracy and efficiency. It has a good promotion prospects.
