I skipped most of all the posts, so heres my take on it, in the electronics industry ( as far as I know) most companys try to make wires, traces, and whatever else any kind of signal travels threw ASAP to reduce EMI (Electro-mag-interference) which long conductors do fantaasticly good at at picking up EMI, think of a long wire or trace on a circuit board like an antenna, it'll pick up a lot of crap signals that you DON"T want, and the other side of it is, every condutor has a resistance, resistance robs power, in most cases the resistance is so small that its barely even measurable but once you get enough then you start losing power and making heat, and in a wires case I beilieve it has a positive temp coefficent (might be negative) where as the wires temp goes up so does the resistance not by alot but in the end it just keeps reducing the power that goes to your motor..

Hope most of thats correct and hopefully I didn't confuse anyone.

Yeah, im thinking that it doesnt matter. Thanks for all the info guys.

I try to use the thickest wires I could find.. too bad they don't have 8AWG silicone wire... and for sensored and sensorless.. I have never had any problem with cogging when using low KV sensorless motors.. In the past, I only had cogging with higher KV motors... It was the lehner motors.. they have two different winding configurations.. I tried the asterisk or delta .. geared for the same speed.. the lower kv setting was much better...
