摘　　要：扭矩是步进电动机的一项重要性能指标。介绍了一套自行研制的基于LabVIEW的扭矩测试系统。该系统利用虚拟仪器技术实现了步进电动机驱动电压和绕组电流的多通道同步数据采集和分析处理,并在此基础上判别驱动电路和步进电动机的运行状态,根据这些状态判断扭矩测量值是否可信。利用该系统,在不同条件下对步进电动机的扭矩进行测量,为步进电动机的工程应用提供了有价值的参考。实践证明,该系统是一套高效率的、高精度的扭矩测试系统。The torque is a very important index of the step motor. A testing system of the torque of step motor based on LabVIEW is described. The testing system makes use of virtual instrument technology to realize multi-channel data acquisition, analysis and disposal. According to these analytic results, the operation states of the driver circuits and the step motor are identified. At the same time, validity of the torque value is estimated with these state analytic results. The system is applied to measure the torque under different conditions, it provides some valuable references for step motor applications in engineering field. Practice proves that the testing system is highly efficience and high precise.
