That's another reason why those Lehners have better efficiency: Longer magnets in comparison to the copper strand layer. The copper "behind" the magnet does nothing for power, it's just electric loss.
I'm almost sure the 1950 has a 50mm magnet, and the Feigao XL have 45mm.

Yeah, exactly. The Lehner magnets alone are rather cheap. And the 1950 already has a 5mm shaft, too.
