Long story made short: I have been trying to build a board with dual sk3 5055 280kv motors. It worked for awhile, but the phase wires on one of them shorted. Dead DRV. So I ordered a better motor (KEDA 6364 190kv) because it’s cheaper than a new VESC. Yesterday, the second vesc died for no apparent reason. I tested it without load before the ride to make sure everything was working, got on, and it wouldn’t go. . Went home, plugged in the board, and it threw a DRV8302 error. Joy. I had the phase wires taped over this time, so it wasn’t a short. There was no visible damage to either of the chips. So I am wondering what caused the second one to burn out.
My current setup is: KEDA 6364 190kv motor (ran in BLDC mode) TB VESC Two 4s 5000mAh 20c LiPo batteries wired in series TB nano remote and reciever Anti-Spark loop key HK lipo voltage meter
Not sure if any of this matters, but the other specs are: TB 218mm trucks TB 63mm mount 90mm flywheel clones Arbor Axis 40 deck
I don’t have the money to upgrade to an Ollin vesc, so my next thing will be a FOCBOX unless I can figure out why the TB vescs keep dying. I would like to stick to vescs, because they are super nice for this purpose.
Pictures: Wiring Looking at BLDC Tool, it seems whatever happened reset the vesc settings too. I verified my settings by comparing with multiple other threads and videos, so I highly doubt that is the problem.
Input from @torqueboards would also be greatly appreciated.
I don’t have the equipment or knowledge to fix the DRV8302 chip, so I was planning on selling the vescs to contribute to the FOCBOX fund, unless I can get the TB VESCs replaced somehow. I read somewhere else that $30 was a fair price. Thoughts on that?
Thanks in advanced!
