Motor cutting out during hard acceleration... VESC issue?

I think something is wrong with either my setup or my VESC, help please.

Setup: SK3 6463 190kv motor VESC-X from Enertion Space cell 3 pro

Problem: I have been riding this setup for around 3 weeks almost daily without any sort of problem with the electronics with the following BLDC settings:

Now after riding around, yesterday I figured I wanted to bump up the braking just a bit and changed the motor min(regen) up to -60amps. Wrote it and put everything back together and took it for a 20min ride and everything seemed fine. Now something really strange happened when when I turned on the battery this morning. I heard a small pop and a spark flew out of the motor. I tried accelerating up a hill and the motor cut off every time the load gets higher.

Hooked up my VESC to my PC and ran for faults. This is what I got:

Well shit looks like I got a DRV failure. But something weird I noticed was the current looks really high for some reason. In all the threads with DRV failures it seemed like the current would be around 0. Does this mean my DRV isn’t fried? What do I do if it isn’t so that I can actually accelerate uphill?

Sounds like the phase wires shorted…

How can I tell? How did they get shorted? How can i fix this?

Look over your cables. Probably broken insulation or something. Or crossing wires inside the motor

5

If a spark flew out of your motor then there is likely a short or intermittent contact in the motor.

How do I fix it?

Try to isolate the problem first.

Sounds like a short in the motor to me as well. Especially since you saw a spark inside the motor. The bad news is that the motor short could have burned out the Drv chip. Disconnect the motor from the vesc and turn the motor by hand. If it feels like the brakes are on, then you have a short. Note: you could have an intermittent short and wiggling the phase wires while turning the motor might make it show up. I would recommend just replacing the motor. ( preferably a motor designed for E-skate) There are numerous sources for these motors.
