I would err on the side of the rotor time constant of like 13 even though it isn't the highest RPM. The graph goes up nice and smoothly, then the rpms start to get more erratic. I think that's because the voltage disk is clamping more severely, which means the PI loop is having a hard time commanding the Id,Iq for those larger rotor time constant candidates.

Also, you can do some voltage and current captures (I'll send that today), and find the stator inductance curve, so we can get sensorless moving!
