Hi, and welcome @rafalspolski!
I’ll try to answer your questions as best I can:
- The SimpleFOC power shield is “in development”. The FETs currently used are not ideal for BLDC motor control, and we would advise you not to use the design as is, but rather wait for the next iteration.
- I don’t have any, but I also wouldn’t recommend it. The Infineon IFX007 is similar, with similar problems. If available, for prototyping you could get TI BoostXL motor driver evaluation boards, these will work much better…
- AS5600 is cheap, but its not a good sensor for motor control. An SPI-based sensor like the AS5047 or AS5048A would be much better. I know they cost more, but there’s a reason for that
- There are many! Trinamics has several motor controllers which do FOC internally, as does Texas Instruments. Also see motors by Gyems, and similar companies, for examples of complete units which include the motor, driver and communications protocols for control. SimpleFOC isn’t interested in these solutions, as we do the FOC in software to be able to understand and modify the algorithm ourselves. But for a product not concerned with the details of the motor control, this could be a better choice. It might save you a lot of development time on the motor side, allowing you to concentrate on your actual product.
- There are many, many, many motors. Would your solution work better with an in-runner or an out-runner? 600W is a fair amount - at 24V that’s 25A - I’m not a product designer, but is that safe? Certainly at 25A fire-safety will be a major concern. Sites like AliExpress and BangGood have literally endless lists of motors. T-Motor has some very nice ones.
- If you have a sensor, don’t bother with BEMF. It’s a more primitive commutation technique, and appropriate to situations where you can start in open-loop mode and switch to BEMF driven-commutation at speed - quadcopters for example. When you need torque at low speeds, and may have high load on starting, then FOC is far superior.
- Sounds ok, within the limitations of that sensor…
Good luck with your project, and keep us posted with the results!! And feel free to ask further questions!
