  • Calculating Motor Torque on VFD Electric motors ...

    Jan 25, 2008· To get the drive to report torque, you will need to reprogram the drive to run in sensorless vector mode. When that is done properly, I would expect the reported torque to be within 23% of actual. An added bonus will be a stiffer, more stable speed under changing load conditions if you tune up the speed loop controller properly.
