VESC Original Hardware

Hi!

We trying to make a motor dyno with two motors and two VESCs 75/300 but the VESC that is controlling the motor is giving ABS_OVER_CURRENT error when a certain torque is reached. The problem is that from the logged data the current values are no where near the maximum current that we have set. 

Attached is the logged data, the MC configuration and the APP configurations.

Hi,

After a motor wizard on my Trampa VESC Six+ via Vesc tool the USB stopped working and the controller no longer powers up via USB.

However when connecting a ST link or battery I get a blue Led and a red led that flashes once every 6 seconds.

Tried to flash via ST link but without any fix for the USB connectivety.

is there a usb chip that might need replacement?

Hello everyone, I want to make a VESC_75_300 now,How can I distinguish the three specific differences of HW75_300_VEDDER_FIRST_PCB and HW75_300_REV_2  and  HW75_300_REV_3? Where can I see them?

I just received my VESC 100/250. Beautiful piece of kit, but so far I've found nothing on how to actually use the board. I've got a lot of experience with PMSMS/BLDC, going as far as to develop them and even teach about them at uni, so the problem is purely the mechanics of an unfamiliar layout and firmware. https://trampaboards.com/resources/manuals/225.pdf is only the briefest of overviews, and does not go so far as to tell me what connections are mandatory (ON/OFF?)

Im replacing the ESC on my Ninebot G30 Max with a 75V VESC.  I am confused about the connections.  How do I know which Hall sensor wire go with each phase?  Im assuming H1 is Phase A, H2 is B and H3 is C.  I have a brake light that flickers when you squueze brake and stays on when scooter is on.  Where does that get connected to?  Its a 2 wire.  Throttle connects to PPM/5V/GND.  What about the hand break which is also a 3 wire?  How does that get connected?  Front led headlight connects to 5V output.  Which do I use for tha? And my addon LED goes to 12V output.

Hello everyone,

I am using VESCs and some of them while flashing with USB, stopped working and even when I tried to flash with SWD I got errors. I found out that in them either the 3.3v or 5v is shorted to GND. Does anyone has any idea why this might've happened?

My own guess is that the 5 to 3.3 regulator is the source of problem but I'm not sure. I would appreciate any help or suggestion to stop this from happening in future.

Best,

I'm working on my second eBike project with a VESC.  Both have used the Sempu T9 pedal sensor.  This second one, however, has a noise problem.  For the longest time, I thought it was a connector issue.  After swapping out cables and sensors many times, I realized that's not it.

Hello,

I am currently investigating various ESC solutions for our project. VESC is definitely one of the best options. I wanted to ask if it is possible to flash VESC hardware with BLHeli_32 firmware and have the ESC function properly as per BLHeli_32 firmware's functionality? Also, just to clarify, the intention here is to of course use the VESC hardware with VESC firmware as an ideal solution, however, to also investigate if another firmware would work on the same hardware?

We have been using a configuration with two VESCs 75/300 connected to a Teensy 3.2 which shares the same battery ground with the VESCs. The Master VESC is connected with TX, RX, GND and 5V to the Teensy and the second is connected through CAN to the master VESC. (The 5V is just to check if the VESC is powered not really powering anything and has a resistor in series to limit the current)

Hi!

Does your VESC-Tool-APP show the IMU data when connected to VESC 75/300? Do I have to activate something so that I can see and log IMU data?

Who is using the IMU of VESC 75/300?

I am very thankful for any reply!

Best regards
