Hello,
I recently started to work on a test setup for torque sensors. I realized that it is difficult to maintain a constant torque on a rotating shaft. If you rotate it manually you have of course the irregular force applied by the person who is turning the shaft. When using AC servo motors, it also generates torque ripple.
Question is: anyone here worked with torque sensors and has an idea on how to apply a constant torque on them while rotating?
(These are steel shafts with two magnetized bands that develop magnetic poles when torque is applied. The test determines if the shaft's magnetisation is uniform and also if there are irregularities in gear and or in the magnetic field capturing unit (fluxgate sensor))
