I can say, with absolute certainty, that a CIM motor will never draw 129 amps, or even 50 amps.

I'm not discrediting your test, as I have done none of my own. I'm more just intrigued by your findings. If your results are correct, it could really change the way many teams design things in the future. So you are saying that your data shows the motor is highly non-linear, deviating from the theoretical model of a permanent-magnet DC motor? Interesting. Do you have some experimental curves produced from the test?

Has anyone else ever put one on a testing rig?
