Using segmented system may also have something to do with reducing hysteresis, but not quite sure on that. It's been a LOONG time since I was in shcool studying magnetic theory.

From my understanding, having more segments would create better efficiency and less resistance with better flow of "eddy" currents. the more segments that are used, the better the conductivity creating less loss? Did I understand that right?

BrianG, right, i don't know why i didn't think of that! Duuuh ;) Honeywell has magnetic core that has 10,000's of laminates, then with ton's of force it's squeezed to together with resin. They are suppossed to have super low losses, if you put a NIB magnet inside them, you can't even attract a small nail to stay on it...

Serum, that's what i was think for the Feigao motors...
