Given the deficiencies of current motor torque ripple test methods, motor torque ripple test system, which is based on virtual instrument, is developed by using LabVIEW platform and data acquisition card. By measuring the motor torque to realize the extraction of torque ripple. The system can display the sensor output signal and torque value. At the same time, it can also realize measurement datas saving and reading. Experimental results show that the test system can better display the amplitude and frequency of the torque ripple. It is easy to use and it has a friendly interface.
