Dear VESC supporter and team,
I've bought two VESC 100V/250A, both show on the same motor the same behaviour. I believe it has something to do with my settings:
Goal: Test the Motor Hemotec 135.20; (135kV; 28pole) with props to reach ~3600rpm (3600*14=50400eRPM).
Setup: original setup 2(2x5s in series, each 5000Ah) LiIon Battery each connected to one VESC. Tried also: 3x(2x5s) for a single VESC; sharing ground
Description: FOC Setup works fine. 158A max current for the motor.
Experimental tab: RPM controlled from 1000 to 50000erpm; 100rom steps; 0,25s waiting (to reduce Amp Peaks); increased Max Motor Current to 200A after few tests; increased max battery current to 250A; for testing;
Problem: At around 40000erpm; motor stops suddenly, erratic on off;
Tried: (more batteries in parallel, but same voltage).
Tried: Google Digging: FOC-> Advanced Tab: Increase Frequency to 60kHz; disable v0_v7 (was disabled)
Tried: Higher Current settings (in case of current limit)
Current max shown in real time: ~70A, a bit jumpy
Problem still exists.
Has anyone a hint for me, or are 2x5s = 10s simply to low for higher RPMs with a 135kV
Thanks a lot for all hints you can give me!
