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?
