Shorting the phases would fry a vesc-based controller, right?
So why not put a fuse in each phase?
It would still fry your esc

no fuse would blow fast enough to prevent the drv from going kaput

It’s another failure point, sounds scary
Fuse might not blow fast enough
Motors see instantaneous spikes all the time, hard to even say what the fuse should be rated for

Fuse is an amp-based protection and wont help against voltage spikes. So drv chip gets fried from overcurrent?
Drv chip gets fried from a cross phase short, as far as I know
I am talking about amperage spikes. Amps spike on instantaneous loads like full-current starts from a motor-still position
It is hard to guess what those might be, theoretically they should never go higher than your settings, however. It just sounds like a bad idea on something that can either help you stop your board or send you into the street

Dont we have vesc firmware that has phase-short protection?
Or can we set the motor/battery current in the vesc tool to protect the esc? (rider safety aside)
Not that I know of
Of course, you can set the motor and battery current to whatever you like
It won’t stop the drv from dying on shorted phases though. This is why we always insulate phase wires, and why MR60 / MT60 are great since the phases can’t short - as easily

Zesc maybe has it.

Oh they can. Don’t get water in those plugs. Thats why I always put silicone in there.
