Re: VESC 6 Beta

Thanks for the updated schematics. I think now I know why I was thinking the new VESC 6.0 can measure a higher current than the old design. You are using 0.0005 Ohm shunts now. But my fallacy was that I forget to bring the gain into account. The current shunt amplifiers build into the DRV8302 have a...

Re: Measuring pole count in BLDC tool [probably solved]

That's a good idea, and easy to add. Thats great to hear and I find this idea also very helpful. There are a lot of motors out there, where you can count the poles/magnets from the outside, but also other motors where that isn't so easy and disassemble some motors is a pain. So a great feature to h...

Re: code to change the motor amp limit

I don't get what you try to tell me with your words (maybe because I am not a native english speaker), but the graph tells me that you didn't came close to your 200A you are speaking all over the place. Not even close to the max measurable 160A. So you are telling everyone in the electric-skateboard...

Re: why the topic “VESC 5” is gone?

I found the website and it looks like there is at least a little bit from the VESC 5.0 thread available. Maybe that is helpful for someone.

Re: Measuring pole count in BLDC tool [probably solved]

Ahh, that would explain why I was counting just 137 instead of 138 tacho counts per revolution. I was using FW2.18 in FOC mode.

Great that it is fixed in the new firmware for VESC 6.0.

Re: How should the VESC "feel" on a board?

Also, regarding the 160A measurement limit, it is true that any current above 160A will not be measured by the VESC. If you set the current limit that high you are just lucky if things don't fail, or your throttle does not provide the full range. In the new firmware I have added support for individ...

Re: How should the VESC "feel" on a board?

Please stop it devin. You are continuing the nonsense threads/discussions you already started on the electric-skateboard forum. You are just ignoring what the people tell you and steel their time with talking about "XXXw at all physically possible rpms", also they told you x times before t...

Re: Measuring pole count in BLDC tool [probably solved]

Yes, my motor looks similar to yours. (maybe yours is v2 in my is v3, so slight differences) Thanks for sharing the picture and confirm my calculations. I also searched a little bit for pictures of an opened MXUS, but couldn't find one where you see all magnets/poles to count them. :roll: Now we hav...

Re: why the topic “VESC 5” is gone?

Sad story. I would also like to see the VESC 5.0 thread again. There was a lot of good information collected. But mishaps happen. It is just crazy how often spam threads are created on this forum. Just saw around seven spam threads on todays morning. So thank you for helping Benjamin with deleting t...
