I’m thinking of getting in on the FOC game but I’m debating what controller + motor combo to use, I found some high torque low kv brushless motors on eBay (4108 motors) but they seem to be designed for drones. (with a stated internal resistance of .1932 ohms, WAY less than the 10 ohms stated here) Since they can pull up to 6.4A at 11V (40 amps according to worst-case calculations using the stated resistance value) this seems like quite a bit too much for the mini to handle. The alternative is to use a 2208 90kv BLDC motor but I can’t find much information online about them and they seem to be quite a bit weaker than the 4108’s. If anyone has experience with the 2208 90kv motors please let me know.
In summary, I don’t think the SimpleFOC Mini would be able to handle a 4108 motor without blowing up, it seems like I’d have to go to the STM B-G431B-ESC1 to be able to handle this motor.
If anyone has experience with the 2208 90kv it seems like this motor would be a better match for the SimpleFOC Mini, but would it be possible to extract around ~.5 Nm peaks from it at 11.1v?
