VESC 100V 250A - don't reach 50000ERPM

Submitted by tobiokanobi on Tue, 2022-04-12 19:29

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.

Increasing phase amps beyond 300a on 100-250

Hi,

I have a QS138 with a VESC 100-250
Vesc tool is preventing me from selecting higher than 300a phase.

It does not give any help as to if this is an artificial limitation or current sensor limitation.

There is a setting under FOC > Advanced > High Current Sampling mode.

Would this allow me to run higher phase current? 

Frank seems to say that he has been running over 400a on a gokart a few years back

There is another option which is the no HW limits FW but I would rather not go for that option if possible.
