I see hairpin windings used in many applications, EV motors, 3-phase alternators, various BLDC motors, but so far i cant find any out-runners of any size. I see them used in starter armatures, so clearly they could go on an out-runner stator.
So the question is, if its good so so many other applications why cant i see any hub motors with hairpin windings?
What would be the main benefit? Efficiency? High power/weight ratio?
If they can make this, why not a hub motor:
