Have you been keeping track of the 4 quadrant 3phase AC motor torque control using STM32?

The idea is to run these 3phase AC motors off DC

I am not sure I understand the question. I already stated the controller type. I have not done anything with STM32 but if it does have proper PWM and timers I assume it can bee done just as easy.

Torque control is more complex than just simply running 3ph AC motor off DC.

Fair enough, I got a bit too greedy with my wants.

Right now, I'm interested in running 3ph AC motor (or brushless DC motors) off DC using STM32 but having a hard time finding good open designs with affordable (DIY) feedback systems.

I can't really help you much here. When I first needed it few years ago I did google search and found bunch of articles on motor control (from Microchip I believe) that also had some designs, Once I understood basic theory I then designed my own circuit that after few tries worked fine. It is highly specialized for my particular product.

What is out there now in open designs I have no idea as I do electronics extremely rarely. I am developing mostly software products.

Ah got it!

I do mostly software products as well with electronics a near and dear hobby. Would love to be in touch!
