Alrightio, first build so it was a matter of time before something came up. So today I finished soldering the three phase wires onto my vesc and plugged everything in. Heres what happened:
the first time I tried holding the throttle I heard a tiny pop / spark from one of the phase wires on the vesc. I don’t know much other than that, sorry, as I said I’m new to this.
The motor will occasionally turn very slightly, a couple degrees, then stop. I haven’t soldered since grade 6 metal shop so I’m hoping I just messed up some solder connection and didn’t fry my vesc or something. Any help would be greatly appreciated. Thanks.
Un-hook everything
Look closely at VESC to see if it shows visible signs of damage
it powers thats good
See if you can get it to work on vesc tool or get it to throw errors
Do qwick hand check on motor to see if it’s fried
Disconnect power! insulate phase leads on motor try with vesc tool
Be ready to pull power qwik if smoke starts to escape
Jeez, I totally forgot about insulating the phase wires. No visible signs of damage on the vesc. Also, how do I hand check the motor to see if its fried?
I literally just fried a focbox like this a few weeks ago…tis a shame. I always just slip loosely some shrink over my phase leads when I’m bench testing but don’t heat it. up
Yeaahhhh, I’m useless on this one. Flux linkage is a thing. I think it’s fixable but not sure… @b264 I feel might know somthing about flux linkage error
sometimes the VESC
sometimes the motor
sometimes both
the motor may be the easiest to check
check resistance of all phases
run a multimeter continuity check on all the phases to stator, shaft, can, bearings
see if there is obvious signs of damage inside the motor in terms of shorts, melted wires etc.
