Oh damn that looks like a ball ache. I’m definitely gonna need to shorten my phase wires. Hopefully its not too difficult with the wire brush like @Static has recommended.

Its enameled wire, i scratched the surface of the wires clean thoroughly with a sharp knife, then put solder flux on it and soldered it. Worked for me i guess.

This means stiff wire, somewhat vulnerable to breaking with movement over time? Here come the silicone wire mods.

@glyphiks it’s possible to cut and resolder, just a bit of work. I hit the copper with 400 grit sandpaper, and in between every strand. Fortunately its not a lot of strands and not fine so it’s not too bad to sand. Make sure the bare copper shows.

Bit late to the party, but yes, all motor wires are coated, else the motors wouldn’t work (each strand would short circuit to each other).
I use the same method you did, flatten out the strands, sand untill they shine, flip em over a few times until shine is uniform - > solder.
Think the “correct” way is to dip them in acid, removing the coating.

Probably a really stupid question but why do you have multiple strands in a wire rather then I single very large strand
Stranded cables are much more flexible and can withstand more bending compared to rigid solid conductors that can break if flexed too many times.
and depending on the cable itself you need multiple for different purposes.

From the looks of it they are not silicone flexible wires? I remember in the old days @longhairedboy said that you must have flexible wires. If not they will break eventually. Almost all motors have them now but hubs are often different.
Yep they’re not silicone wires. The copper in the wire is pretty much the motor windings.

Abraision resistance in most chepo silicon wires are pretty poor tho, They can take heat all day long but if you stick your fingernail on the isolator it breaks very easly.
Worth a thought since the cables to the hubs are on the exterior

Would 0.5 Hydrochloric Acid work for this?
