Does anyone know if any of the readily available vfds that will control torque at 0 speed?
The need for this is on a 60hp motor.
This is for a potential test rig. The rig is going to have a motor driving a test piece. There is going to be an inline torque flange in the shaft. For calibration, we have thought about using a torque arm connected to a load cell in such a way as to lock out the rotor. If we could control the torque on the motor at 0 speed, we would be able to load the load cell and the torque flange.
I know this is possible with certain large drives (I know this is done on UNICO motoring dyno drives). Does anyone know if this is available on any off the shelf drives?
Thanks
