Cool article, engineers gonna engineer! Two things that jumped out to me: it’s incredibly seeing copper being compared as the “cheap” alternative! Obviously it would be compared to rare earth but copper is typically “expensive” in general or household applications. Also, I had no idea Tesla motors spin at up to 18k rpm that’s just bonkers. Guess it makes sense because they’re single speed(?) Dang, old diesels (kind of an extreme example, I acknowledge) redline at like 3500 rpm.
