Re: Solar car races

Hey, nice to here there is still some interesst. I see you posted at Fallens thread, too. Do you have some specific scenario to use a VESC+ for? The latest commits in my github repo contain some minor bug fixes and optimisations. Beyond that the design is pretty much final. At the moment two prototy...

Re: Solar car races

Mhh, that const is interessting but I can only find references to it in the BLDC code (mcpwm.c). I only use FOC mode and the issue is there, too. Therefore I doubt that this is the cause to the problems. I also noticed that in FOC mode the triggered graphs are not 0 centered. It typically does not m...

Re: High Power VESC

Well, it is open source. That does not mean that I use github as my official release channel. If you want to use my design you will have to use my EDA toolchain, too. ;)

Re: High Power VESC

Hi, just found your project of implementening what I call a VESC+ xD First up the DRVs are very sensitive from end to end. Benjamin himself had issues with the DRV dying because of a inappropriate layout. I am not exactly suprised that it did not like your wiring^^. Just forget this chip. I realy do...

Re: Other voltage scaling.

Well, the STM32s are pretty unforgiving regarding over voltage^^ Not a AVR which can run on 12V just fine xD I just posted about the voltage divider issue in my own thread regarding the HSWR. The firmware indeed does not like it if the division factor is changed. To get it running anyway I just left...

Re: Solar car races

Hey, me again! I have a mysterious issue with the observer algorithm. I ignorred it for now because I found a crude workaround which I now want to fix for good. The problem occurs as soon as I change the division factor of the voltage dividers for the phase voltage measurment. As long as the Motor i...

Re: Solar car races

I am making a high voltage controller too, will be releasing it shortly, next few days.

Uh! I am exited!

Are all components Q-100?

Most of them are and the rest should be available Q-100 rated.

Re: Solar car races

The motor in the video is our second generation radialflux motor. It is custom designed and build by our team. Interessted in one? :mrgreen:

Re: Solar car races

At the moment both are 0 but you can try for yourself. Let's write a little update if I am already at it: I got the motor running pretty reliable now. A few issues are still unsolved. First up the voltage dividers are a bit finicky. I am running higher input voltages which requires a higher division...

Re: Solar car races

Well, I got some realy good news to report. I started setting up the lab for benchmarking the controller yesterday and got my first results today. Staring small with 12V in the intermediate circuit und 1A motor current limit delivered these results: https://youtu.be/v2nc7Fdntmc Note: The motor is co...
