Motor dragging-test system based on virtual instrument technology

Since the traditional transducer performance testing method has a big error and long testing cycle,a novel transducer testing system is designed.The dynamic and static performance testing of the asynchronous motor was realized,and the assessment of the transducer's performance and parameters was completed by taking the data acquisition card and industrial control computer as the hardware platform,LabVIEW as the software platform,DC motor as the load,and adopting the high-performance controller which can operate in four quadrants.The agility and simple modularized program of LabVIEW makes the research and validation of the testing system more expedient.
