RIP TSG Pass you served me well

Good thing you had a helmet on!

Glad to see the helmet got most of it and you’re alive and in one piece.

Sorry as usual I’m late to the party… but I’m glad your that was one hell of a fall.

The TSG helmet served you well. Good safety investment.

I had two TB vescs die in foc using 12s. Until someone can build a reliable 4.12 vesc pushing 12s in foc, I’m sticking with bldc. I loved how quiet and smooth it was but not enough to always be worried about when it’s going to die.

Is the focbox not safe in foc?

I think it was a problem with the fw more than the physical VESC

Evidence points to hardware failure, but it’s possible it’s fw.

@Hummie i was using Ollin vescs

Hardware failure seems almost nonexistent with chaka vesc…

Firmware failure with 3.29 also seems almost nonexistent though…

i could’ve made the drv blow easily on fw 2.18/2.54. FOC was running way less smoothly in those fw’s

Thanks for video…

Shoot motor lockup is my biggest fear after riding @mccloed board lol. Glad your okay @Jinra

one of my Vesc-X/FocBox failed on FOC. I assume it was my setting error that did something, hard to tell if it’s hardware issues since only one failed and the other still works in FOC, it’s still on its way to @JohnnyMeduse. This is scary as hell since I’ve been using bldc for well over a year with no issues. Most likely going to stick with BLDC, don’t want to buy more vesc just to fry them or get injured.

Rest up @jinra. This is why we push to protect our melons

Well, I’ve been using foc on FocBox for more than a year now, with the old firmware of course, without glitch or a problem. I don’t think the issue is Hardware related.

In this case I do believe it’s a hardware issue as I was able to get DRV fault to trigger once on the bench, but it runs normally most of the time. I might be toasting my DRV so I’ll leave it on bldc for now.

There is also the case of the perma braking FOC mode, which may or may not be related to the DRV issue.

And lastly, there is one more issue wither other people who use 3.27+ f/w and have perma braking FOC without ever even running the motors.

When your focbox was failing in FOC mode. Did the motor just brake ? Or did the VESC simply just power down, and leave the board Rolling ?

It was working fine after a few initial tests when I was building, then the last run I did had weak brakes so I was rolling to a stop. It turns out only one motor was working. Plugged the FocBox to the computer and got no fault, inspected everything and it seemed fine. I reset the FB in question and ran fault again, it gave the dreaded DRV failure but nothing else, wasn’t able to get it up and running again.

Motors are new and nothing was shorted…the other FB works fine and turns both motors so off to the DRV wizard it went.

Not sure what your wheel size and gear ratios are but 35mph seems awfully close to hitting the vesc’s know ERPM limit of 60,000. I’ve gotten it to give me a drv fault on the bench but never had the balls to go that fast on the road. So glad your ok! Helmets people hemets!

Depends entirely on your gearing, but for me 35mph is about 50k erpm.
