Maybe the test could be done at low current. I know you can have absolutely no idea as to the right rotor time constant, and still control "Id" and "Iq". They will even be 90 degrees apart, but they just won't be the ideal field and torque component. The more I think of your idea, the better it sounds.

Freebeard, you can submit the code anywhere you want. I will even be happy to allow the irs to email me and download it. One concern I have is, are you depending on a boost section being done by me any time soon? This would be a major undertaking, and a new board would need to be made, using a different microcontroller that has 4 pwm channels.
