Guys really getting excited about version 20, stil...
Thanks

Would love for you to test the 0.20.0 and give some feedback! But I understand you are waiting for the stable release. Everything in the 0.20.0 should be really tight and well controlled without any bugs.
I have looked at the FOC and there are several ways to improve the efficiency and torque. This would result in a cooler motor with less heating but with the same or even more torque. This can be done just by optimizing the existing code and functions. Adding field weakening will increase the cadence at the cost of efficiency but this can be acceptable in many use cases.
I see these changes as one major upgrade in the future! But to do this properly we need some serious instruments to really accurately measure and validate the changes and values. You have a suspicion that the static value we use in the experimental mode is not the most optimal and this is most likely true.
If I were to do some testing I would remove the motor from the TSDZ2 enclosure and install it in a motor torque dyno. Would make some extensive testing in the lab and then adapt the firmware for maximum efficiency = maximum torque at any given load and speed.
I think one user reported that we are around 60-70 % efficiency. In the best case scenario we would maybe be able to get to 80-90 %. This would mean that the actual torque increase would be around 50 % from the current 0.20.0 Beta 1! And we would have far less heat developing in the motor!
Sadly, we would have even more stress on the system (bye bye blue gear!) but that is another problem :wink:
