Just went for a ride and noticed that above a certain RPM my motor started making this high pitched metallic noise. It disappeared as RPM kept increasing, and reappeared as RPM decreased to the previous level. Also, after the ride I had this ABS OVER CURRENT fault code.
The motor does the same noise without load.
Before the ride I had adjusted Motor Min from -45A to -55A and Batt Min to -25 from -12. I switched back to the older settings, but the issue remains.
Other than that settings were the same as on previous rides. I had also adjusted the motor mount so it was better aligned to the wheel.
My setup includes A single 6374 sensored motor from eskating.eu ( @fottaz ) FocBox 10s4P 30qs and SuPower 60A BMS and I’ve been using the extended BLDC tool to set up FOC.
Have always been running in FOC-mode with no issues.
Any idea what this could be and why I got the over current fault?
