VESC Original Hardware

Hi There,

Best way mode to control a sensorless  axial flux motor ....BDLC or FOC???

Regards,

Hi,

 I am using VESC 100/250, we are testing our prototype motor. After detecting the Hall sensor position, we are not able to run the motor. While debugging, we identified that the VCC pin and GND pin are showing short.

Requesting your support to solve this issue.

Hello

My friend tried to connect led through DC DC convertor to the FSESC 6.6 board

And after that 1 of the motors stopped working

After opening the board and checking for shorts 

He has short on the 3.3v on one side 

But if I conect to usb and vesc tool 

I can access both mcu local and can one 

Can it be a short in the mcu? 

Or if I can access it through vesc tool it isn't possible 

Hello.

I wan to check the VESC CAN message with Arduino. When I connected Arduino uno and mcp2515 to the VESC CAN pin, I couldn't get any message. How can I read the message?

And after this is solved, I want to control VESC via CAN communication. Is there anything else I need to modify other than code modification?

Please help me!!!

Hi! I designed VESC6 MK5 custom board using VESC6 MK5 schematic and all functions work well without any problems and both VESCs use 5.3 version Firmware.

But I tried to control two same boards using CAN communication but I cannot communicate two boards using CAN communication.

It seems the master VESC6 MK5 cannot find the slave VESC6 MK5 when I scan CAN device using VESC tool, I use VESC tool 3.01 version and it shows local CAN device only.

Problem Summary: Using Trampa VESC75/300 in a heavy robot that needs to be able to operate at temperatures down to -20C. Below about +20C the VESC will not run the motor smoothly at high torque/low speeds for some period of time after the VESC is turned on. For 20C this lasts about 1 minute. For lower temperatures this can be many minutes of poor performance making the robot drive very badly. Once the system is warmed up it functions smoothly with great torque and power.

Hi,

I am creating a (FOC-)model of my VESC6 driven RC-car in simulink. My simulated responses are not yet the same as the physical responses of the car (the simulation reacts slower). And now I am wondering wether the the PID gain values as displayed in the VESC-Tool are for a continuous-time or discrete-time controller. And if they are for a discrete-time controller, which sample frequency is the VESC6 using?

Currently I have copied the PID gain values from the VESC-Tool to continuous-time PID blocks in simulink.

Hello friends, I'm new about VESC and as you can see from the topic I've been struggling about getting RPM data from the VESC 4.12. I want to get it via UART and my receiver is a STM32 MCU. I couldn't see any examples that I can follow about STM32 (there are some examples on Arduino). So can you suggest me any solution about that?

Hi everyone, we recently got our VESC 100/250s in and I can control our motor through the VESC tool just fine. I've been trying to find some information on how to send commands to the VESC over CAN but haven't had much luck. I tried to mimic what I saw online from a couple of different projects but to no avail. (https://dongilc.gitbook.io/openrobot-inc/tutorials/control-with-can, ht...).

Hello Makers,

I found original 100250 could handle only 180A in a hot day. I have ventilated cooling with big radiator..

To improve performance, I milled copper block...
