VESC in Road Vehicle

Submitted by hockinsk on Sun, 2020-10-18 13:57

Does anyone know of a VESC suitable for use in road vehicles? I notice the warning in the VESC manuals suggests using one wouldn't satisfy approval for vehicle/road use.

I have a small rear-engined microcar i'm looking at converting to EV. Dual VESC 75/300 would work for my power needs. I read up on the Axiom VESC project but the specs are complete overkill for my needs.

Hall sensors + incremental encoder

Submitted by SAK-SIVAL on Thu, 2020-10-08 18:37

 

I am working on mobile robots and during some phases of operation need high position accuracy in the robot wheels with high torque at low speed, but do not need absolute position.  This is different than robot arms that need an absolute position at startup.

I'd like to use wheels that have an incremental encoder with no index as they are readily available and lower cost.

Implementing developer tools and PID tuning

Submitted by nowholeself on Wed, 2020-10-07 07:04

I've just switched from an ASI BAC800 to a VESC 6.6 on my ebike. So far the VESC is working well. But I'd like to be able to field weaken as on my ASI. How does one implement this experimental feature into the app or pc VESCTool? When I import XML files into the developer editor, nothing shows up in the VESC tool itself. A step-by-step would be helpful. Also, I'd like to tune the PID. A step-by-step would be helpful for that as well. Anyone have any links? So far my searches don't turn up much. Thanks.

VESC on an STM32F4 Discovery board

Submitted by sonnbc on Tue, 2020-10-06 06:55

Hello,

I'm trying to play around with VESC firmware on an STM32F4 Discovery board (that uses an STM32f407VET6 MCU). My grand goal is to eventually build a separate power stage and use this board as "the brain" running VESC. However, I got stuck as the very first step: making VESC-Tool recognize the board. 

So far this is what I have done. There is no power stage, etc. yet. I'm just using the board itself:

Arduino UART max Current and max RPM setting

Submitted by h2omatt on Wed, 2020-09-30 23:49

I am working on a project where I would like to set the max rpm and max current. I was testing using the SolidGeek VescUART library. I was commanding setCurrent and then SetRPM in the main loop. it seems that when using setRPM the motor vesc defaults to its motor current max and overrides the setCurrent command. 

Do you guys have any thoughts on how to make this happen?

On MOSFET choice and replacement

In the product description of the VESC 6 MKIV I read:

In its development, no Mosfet switches were used - due to their tendency to eventually blow up. This saves on the additional costs of replacing them, & also adds to the longevity of the VESC 6 MKIV.

I thought "Cool! Maybe they went for IGBTs", however in the schematics I see that the H bridge is composed by six IRF7749 which are... MOSFETs!
