A New High Speed Frequency Conversion Grating Torque Measurement System

摘要：

It is difficult to measure torque of high speed rotating machinery, a new mechanical structure torque sensor based on three phase asynchronous is designed, and combined with frequency conversion, a new frequency conversion Torque Measurement system is constucted. The sensor shaft and rotor are separated by bearing, for the accuracy of torque measurement, controlling frequency converter to make the speed difference of sensor shaft and rotor constant. This measurement system based on Filed Programmable Gate Array in signal processing, SCM in data processing and frequency converter controlling, and realize noncontract torque measurement. According to the results of the hardware test, indicated this measurement system is realizable. The good accuracy of measurement system is verified accord to the test, the fiducial error is 0.2％F.s.
