This is what I’ve seen explained as well.

Motor Efficiency Discussion

I have yet to see a numeric factor but it’s coming down to the efficiency of series motor windings (delta) vs parallel (wye) Sharts and hummie would always claim higher kv motors are better at heat disappation because of joules law (copper loss proportional to I^2 * R) But then while I was separately looking up motor can materials earlier I read this: " There are two common electrical winding configurations; the delta configuration connects three windings to each other (series circuits) in a…
