ABSTRACT:
A discoidal armature for dynamoelectric machines has its winding conductors bonded together in a rigid structure by means of a resinous material, and its commutator bonded to the structure. The structure has a disc portion containing the coil sides and outer and inner ring portions containing the coil end-heads and other end connections. The coils have their sides and end-heads of shapes which permit them to nest closely together in an annular array of overlapping coils. They are stranded and have the strands in their side arranged to provide a tapered disc portion which is thicker at the inner ring portion than it is at the outer ring portion. The commutator consists of an annular array of segments bonded to the disc portion adjacent the outer ring portion and presents a working face on the side of the disc portion. A similar array of segments can be bonded to the other side of the disc portion to obtain a duplex commutator.
