I’ve encountered a problem with my focboxe. it was running fine in FOC For the last few weeks. The last days it was running, it would detect a bit higher values for the foc motor detection. But still would run fine.
I took down the board to redo the battery pack and switch wheels. Now after connecting everything again it constantly fails motor detection. The motor is just stuttering and hardly turning. What I‘ve done so far:
- Reflash Firmware, motor detection in BLDC & FOC both failed. I tried the original firmware as well as akmaniacs.
- Changing phase wires, tried each combination. Failing as well.
- I don’t use the hall sensors. But I still tried Sensored and sensorless. No difference.
- I checked the motor cables for continuity and they all seem fine.
Would this point to a defect FOCBOX? Is there anything I can check on the board/measure ? I will make sure to upload a video later next you guys can see what I mean by stuttering.
