Some folks wire their motor wires directly to the VESC, which seems fine. I’ve noticed that some, however, have these connectors that they solder to the board instead of a wire. This is an image I 'capped from one of @onloops’s videos:
Those red, yellow, and blue connectors; what are they? Are they a special right-angled 4mm bullet connector? Is it possible to solder a whole, regular, 4mm bullet connector right onto the VESC board?
Thanks @lox897@torqueboards@lowGuido. I was hoping there was an L-shaped bullet connector out there somewhere! I was thinking that there is some value to keeping the motor wires modular. Then they can be easily shortened or extended without having to desolder from the pcb.
Any thoughts on using a very short wire for the motor connectors on the VESC, perhaps 3cm? (so it would be wire soldered to the board, a short wire, and then a bullet) Then some extensions (12AWG, 4mm bullet) to reach the mounted motor connectors? I’m unsure of the impact of adding another connector into the chain, and that’s not how Vedder does it
the ones in the picture lox posted are soldered on both sides, so there would have to be a slot cut to allow the PCB to slide in the middle and have solder both sides.
you can add as many connectors as you want. I try to avoid it because it just ads another possible thing to come un plugged, but its all up to you. there is no wrong way to build an e board.
personally if it was me, id probably solder on the 4mm bullets that match the motor so that you can just plug the motor direct to the ESC.
Thanks @lowGuido, I agree; I’ve got the 4mm bullets to use. I’ll need to extend them somehow; I don’t think the motor wires will reach the VESC otherwise.
