More laminations make for a more efficient stator (one on the right).
It reduces edy currents which do nothing but make heat, which I think we have all concluded is BAD
I showed this picture to an Electrical Engineer buddy of mine and he was astonished at how thick the laminations are in the BMW version.

Alas, if ElectroSport can't wind the thing properly it doesn't matter -- Hopefully the winding short-circuit was a one-off.

It would be interesting to measure stator temperature of OEM vs. ElectroSport with and without header wrap....
