Some follow up pics of the enclosure, 95% done. This was in the hand pump vacuum bag which worked perfectly. It’s painted now. Will add a few final photos.
Dealing with this DRV error that came about recently while running at top speed. Went away for a while and came back the other day. 10S190KV now with 10S3P.
40/-40, 25/-14 batt FOC. Temps never been above 50C
If I grab and hold one wheel and run the other wheel to top speed on the bench, the motors each spin fine independently without strange noises or hiccups. If both run, I get a surging that comes with a strange harmonic sound. Also like they are grinding or something.
The noise happens right before the power drops.
Appreciate any input. Will have to test these more. For now, I’m installing the 6.6 dual plus I have handy for another build. A dual 100amp 6.6 is a bit overkill, should run just fine and it fits.
While also installing new grip tape and changing some colors, the FG I laid up before delaminated a bit. I was able to actually muscle the whole sheet off both sides with a chisel. That was unexpected, and the last time I’ll use bar top bulk epoxy.
So now I’ve removed all of the old threaded inserts from the 3 different enclosure variations that were on here in the past, filled them. Laid up fiberglass and two layers of maple in the roarockit vacuum bag. Never easy
