Vesc 6k limit is 150k…could it be a reason elsewhere?
I switched to BLDC mode, no more cutouts, evetything working perfect. Miss FOC a little bit just for launches.
Stewii sent me some procedures to pinpoint the issue but I still need to find time to open up the enclosure

Just finished my first one… some parts didnt come so I borrowed them from an old vesc…while flashing the firmware there was smoke…sigh I’ll report back when my 2. iteration of parts arrives…
Can you get a closeup of the DRV?
Is that flux or solder? It should really be cleaned up to properly inspect, solder balls floating around
And what’s going on here

To be honest this is the first smd soldering I’ve ever done. So its learning by doing so this was a 80$ lesson so far…

I have an inrunner 5000kv and tested it with a 3S battery (specs says 2S max) and got about 100k erpm. Here is a printscreen, top is BLDC and bottom FOC.

absolutly wonderful! great to see its bullet proof at high erpm
If I aquire a new skill im the process I’m okay with ruining s couple boards 
I also learned to never order the exact BOM since parts cost fractions of pennies sometimes.

Yes, but by ordering not exactly the same parts (lower quality for fewer pennies) you might add one extra “O” to the BOM.
I meant order more than exactly them BOM because the little parts are never to be found once dropped and dont break the bank to order 50 instead of 4.

That makes sense.
Hot air I think my stencil was too thick and added to much solder paste…
Hi Stewii,
At those high erpm, are there still any noise differences bewteen BLDC and FOC?!
