i am confused on how to place my magnets on my steel plates as per hugh's book....i am using 3 phase(4 coils each phase)(12 coils), and 24x1" dia. neo's for magnets...are the magnets layed out concentrically or are they supposed to be staggered and if so, how?..also, because this is a dual rotor what fields(north or south) are supposed to be on each steel plate? thanks ...randy
