Abstract
The series wound, air core (SWAC) homopolar generator includes a pair of ls connected in series with a rotor having a pair of slip rings joined by conductive bars. To reduce eddy currents induced in the slip rings, their radius and axial length are chosen such that the circumferential and axial resistances of the slip rings fall in a bounded region wherein the axial resistance is minimized and the circumferential resistance is maximized.
