VESC in-air startup failure

Submitted by jschall on Sat, 2025-04-26 00:56

Hello,

I am using (somewhat modified) VESC on an unmanned aircraft. We are running a trampa mkvi hp and a 220kv brushless outrunner, sensorless. I've set the startup settings so that they limit startup current only, there's no open loop at all afaik. I've tested thousands of starts, stops and reversals on the ground, and have been building hours in the air on around 10 separate aircraft.

Everything has been going well, except we had one aircraft that ran into 2 startup failures in the air, on the same flight.

No activity in CAN analyzer

Submitted by PutridFox on Sat, 2025-04-19 08:52

Hello!

I'm wondering if I should be able to see any activity in CAN analyzer? 

I have a Spintend Ubox V2 75V 100A X2 and I can see that CAN is working as I have two ESCs under CAN devices and both motors are spinning when applying throttle which is connected to ESC A.

Still CAN analyzer is silent.

I have CAN status rate 1 set to 50hz, status 1 to 6 ticked. CAN baud rate 500k. CAN mode VESC. 

Do I have to do anything else to 'activate' broadcasting of CAN messages? 

Repurposed Hyundai Ioniq HSG Hybrid Starter Generator as motor - crunching/cogging

Wanted to see if anyone had any advice for getting this setup working cleanly on my build.  The "motor" is a Hyundai Ioniq HSG.  I removed the resolver and installed a hall effect sensor setup in place of it.

I simply machined the orignial pulley down to a flange, then bored a sprocket and welded it to make a sprocket for the setup.

Remote pairs but motor does not spin after VESC tool use

Efoil worked but had low power so I used VESC tool to attempt to get more power.  Now the remote will not activate the motor.  The display is showing all the data of both battery strengths and throttle position, etc.  I did a firmware update and ran the wizard and everything seems to work thru the tool.  Any ideas of what I did wrong?  TIA.

Seeking Feedback: Controlling VESC via Web Interface

Submitted by fjolivet on Sat, 2025-04-05 13:00

Hi all,

I'm developing a web application to control a counter-current swimming product using a VESC. The goal is to monitor VESC data and create a custom interface for training purposes.

Current Progress:

  • Successfully connected to the VESC via Bluetooth using the same UUIDs as the VESC Tool project.
  • Sending getValue packets over Bluetooth.

Issue:
