Abstract
A dynamoelectric machine, of the direct current type, with a circumferentially segmented stationary magnetic field structure providing magnetic poles including diametrically opposed pairs of north and south poles, with intervening poles of alternating polarity; rotor conductors extending longitudinally and selectively interconnected in sets providing a plurality of series current paths each traversing a plurality of stator active pole regions; and a pair of brushes for current collection at one or both machine ends.
