Hello, I have a three phase brushless motor and was trying to measure its torque and speed using a torque sensor. The motor will first go to its maximum speed which is about 6000RPM, then I applied a brake to decrease its velocity. Here is what I get as a result of data acquisition : The problem is that the torque signal looks kinda mess up. I wish to get a signal as nice as the RPM. Does anyone know how can this be done? Some kind of signal processing steps? Please help me.
