Papa!!! HAHAHA.
Awesome! I've been studying sensorless, and it's not easy. But if you get everything just right, it can keep the d and q axis within about +/- 1 degree from 90. I also finally figured out the space vector modulation. Now I think I can do all the software without having to look up any formulas or anything. Just do what makes sense mathematically from start to finish. Finally! The driver section is basically done. It's going to drive from -8v to 15v or so. I've found some TO-247 plus igbts I think I want to use too. They're only $6 each. Rated for like 210 amps each, but I'll only run them at maybe 75 amps peak per device.
The whole thing should be just maybe $400, but good to maybe 50kW I'm hoping.
