It’s what you get with limited data :
I don’t know if VESC-Tool 2019 advised motor current depends on motor resistance only.

No interest unless this process is automated, feature request for VESC Tool?

@taz Very cool thread. I somehow missed this one. I didn’t know the new VESC tool had this feature. Looks like a good way to take some of the mystery out of all of these different motors. I’ll do some searching, but do you know off hand if the new VESC tool is compatible with older 4.12 VESCs, FOCBOX’S, Flipsky 6.6’s? I’ve been wanting to take the pile of motors that I have and do some actual KV testing on them but this would be one better than that.

Yes it is. On my Evo I have focboxes and it works perfectly fine (after you upgrade the firmware ofcourse).

I forgot to add that I have a metr pro bluetooth module in that one.
I don’t know if it will work with a hm10 module.

It seems it does. If you do the calculations it appears that the tool sets 60W thermal losses as the limit and calculates the max current using Ohm’s law.

@hyperIon1 @PatRocks or anybody else who already received the 6880 190kV motors from maytech, would be nice to see what the new vesc tool says about those motors and if it is close to the specs maytech gives.

I think @PatRocks can when he is back from holiday. I won’t have any until the end of next week to test.

Hey I think this thread is awesome. I tried searching a similar thread but didnt come up with anything good. Just a few small threads here and there, most quite old. I got here by finding a single post in thread about a different subject, that led me to vesc project thread on the same thing, then a link that led me back here to this thread. So I changed the title to make more easily searchable.
This is my motor its
Racestar 5065, 149kv, 67mOms.
Its been thrashed for two years so I dont know if that has any effect but the resistance is quite high even for a 149kv motor?

Considering that the torqueboards 5055 190Kv is 40 mOhms and they have the same size stator, 67 for 149Kv sound about right
As Kv goes down resistance goes up for the same motor
What is the factory kv rating?
