That is way cool. And almost painless. Thanks.
To be honest what I had hoped to find was one I could plug into a circuit to see the effects of PWM frequency, regenerative braking etc. I'm wondering if I could put the schematic models into an asc file and add a motor symbol. Or maybe such a thing already exists.
But if all else fails I can move forward with this and some paper its just reassuring to see the plots sometimes.
Thanks again Carl!
