I need some advice from all the FOC gurus here.
I have a 65121 that works great in FOC mode with 15s batteries.
With 10s it’s a completely different story. The motor doesn’t seem to have a lot of power and starts clunking if I pull too much throttle (can’t get on foil because of that issue).
If I switch from FOC to BLDC, the motor has plenty of power on 10s and no clunking.
Here are the FOC motor detection results:
- Motor Resistance (R): 61.2
- Motor Inductance (L): 67.24
- Motor Inductance Difference (Ld -Lq): 46.79
For comparison, I also have a larger 65161 which runs great with 10s and FOC.
