VESC Tool

I'd like to determine the KV of a motor. what's the best way to do this?

Is that what the KV command in terminal does? how does it work? how do you use it? I've randomly got it to respond 0 kv or some other number but clearly I don't know how to use it.

I assumed realtime data spinning at a fixed duty cycle controlled by vesc-tool would be needed. but I still get 0kv except for when I randomly didn't. not sure what I did different.

I tried on a fresh installed windows 10 on a Think pad laptop.

Same as the previous versions: Just a blank white window.

Tried with compatibility check to all other versions of windows, or running it as admin.

Put it into the two programs floder or the desktop but nothing helped.

The only machine I can get this program to work on is my desktop in my appartement, but it's hard to lift my bike up two stories, make an adjustment, then test, then lift it back.

Any ideas?

Hello everyone,

I'm currently working on a 4012 480KV from T motor, power in 22.2V with a 15*8 propeller. 

For now I use BLDC but results are not good so I wanted to use the FOC command mode. I make the motor pass the detection but once I write new values and try with Duty cycle input most of the time the motor don't follow the command or have difficulties which I believe come from my parameters for the test.

Hello guys

When i try to connect my phone to the nrf wireless dongle

I get an error about firmware not recognised make sure the port is assigned to the vesc

Any idea how to fix this?

Hey there, I'm trying to build the vesc tool and it's a pain. Has anyone done a docker image that wraps all this? I'm making a docker image now but it is pretty rough going.

Thank you

Hi guys,

i have issues with motor cogging. it was running fine for the first two month and few days ago it started acting weird. it will start cogging, high current draw low torque and speed .....

i am using fsesc 4.12, latest firmware. ive check vesc for faulty components with multimeter (mosfets, and resistors for them) and values are looking good. i have compared them to vesc 4.12 schematicks.

ive also checked motor with lcr meter and values are also looking good, i think :) bellow is table with phases inductance and resistance 

hi guys,

few days ago my motor started acting weird, i have weird cogging in my motor and vesc print faults will report this abs over current fault. i have provided fault and screen shots of settings. ive visually and with multimeter checked vesc 4.12 and motor. i have found no issues 

any help is appreciated.

Hello, is there a way for me to create a custom battery pack data set to be selected in the battery dropdown? I am not sure if the settings preset in the three options for battery type make any difference, but the pack and cells i am using are for sure not in the category types available. My main concern is that the Wh consumed numbers being displayed form my rides is just not accurate. It said on one ride i use 550Wh, but i only used about 40% of my total pack capacity, which is in total only a 437Wh pack.
