Even with 6s I am getting drv8302 errors. Seems to happen after the motor heats up a bit. Happened about 5 times on a 25 mile trip. No problems giving it full throttle at a stand still but seems to be just random giving the error, a few times after stopping then going and a few times getting to top speed. I am going to ditch the usb connector and solder it directly to the wiring and see if that helps.
Are you using sensored mode only and not hybrid?
Yes. I wanted to see how much more quiet it was then sensorless or hybrid. Tonight I am going to try hybrid mode.
There should be no difference in how quiet it is. Sensored is not nearly as good for high speed since there are filters on the hall sensor port that introduce delay and I haven't implemented anything to compensate for that. The higher the speed the more the timing will be delayed, which is the opposite of what the motor needs (timing should be advanced at high speed, not delayed). Hybrid should work much better in all aspects than sensored only.
