VESC Tool

Hello. Can you help us with the following issue:

We are going to use VESC for driving tail rotor in helicopter. Tail rotor has foldable blades.

It is absolutely necessary to drive in duty cycle mode with no braking. The main reason for that: blades can make vibrations or even fold during braking.

What i tried for now : setting motor and brake current 0, and it did not help.

What else can i try ? Change parameters or may be some modifications to the code can be done?

Hi . I control my VESC using a 10K pot on the ADC input, this is working fine

I need to set the max RPM to a much lower level max around 3000 RPM

I reduced the ERPM value to around 35000 and sure enough its about the speed I want , however 

this occurs at around 1/3rd of the pots revolution and for the other 2/3rds it just sits at that set max speed.

The trouble with that is I only get a small rotation of the pot from 0 to max speed .

Is here a way to set it so I get my reduced max speed but spread over the full travel

The VESC Hardware Version 6 shows some erratic behaviour with the saving of the Motor and App parameters from the VESC-Tool to the VESC controller.

Steps to reproduce:

Hello to you out there.

We have purchased the Platinum version, so we are up to date.

Atm we got 48V 14 cells battery, 2 single VESC HW 4.12 FW 4.2.

Motors are 2 BLDCs and they are controlled by ADC throttle.

We setup the master and slave as the following short instruction:

Hey all, 

I have searched for this issue and have not found a solution yet.  I am using the VESC with a throttle in Duty cycle mode ( I know of the differences between current and such, we just need duty). I was wondering if anyone has found a way to limit the current spikes when changing the throttle.  Right now i'm seeing lots of current pushed to the motor when changes in throttle happen.  This is a bit Jarring.  

Electric skateboard was working fine, it was a bit sluggish so I wanted to tweak some settings. I Load up the VescTool Configure my motor, Run the controller set up, the program reads my input from the controller fine. Disconnect the Vesc and my board will no longer read input from my Vanpro Controller. Any way to fix this?

Hi Everyone,

This post is about motor tuning for a drone on VESC tool. The hardware is a VESC 6, and this is related to a post I made more than a year ago about the KDE 2814XF-515. I had trouble tuning that one and still don’t have a firm grasp on these parameters, the tuning process and how to optimize this better. Here is what I’ve been using for the KDE 2814XF-515 for the last year to reasonable effect.

R = 62.0 mOhm (for a quoted 130 mOhm motor this seems about half and correct)

L = 6.41 uH

lambda = 1.459 mWb

Kp = 0.0107

Hey,

Does anyone know that the difference is between "current in" and "current in setup" in the log file?

In the RT data logging help/Info area, there is just limited information.

  Thanks a lot !

SOLVED

Hi,

I am trying to compile the vesc tool mobile apk version. I enjoy using the app and it is awesome. But I would like to have the RT data screen as the home window and auto scan/connect.

So far I have compiled an apk but it is the full software version which you would use on a tablet or a computer. I have done this in QT creator in a linux VM on windows 10

So my question is how do I compile the mobile version?

And a tip on if it is possible to open the app layout in qt design and if so how would be nice.

Trying to use VESC to drive the blower motor in a car. Yes I know it's not wise to use hobbyist quality parts for automotive applications... 

The PWM speed signal from the 2009 Camry is open collector, so that means lower duty cycle maps to higher speed.

Is there any way to change the mapping to do this? I was thinking of making the throttle curve have a negative slope, but can't do it. In the PPM app, I also tried changing

"Pulselength start"  = 2 

"Pulselength end" = 0

but that didn't work either.
