ABSTRACT:
The coil structure for a discoidal winding for use in an axial gap dynamoelectric machine includes a continuously wound substantially flat annular disc portion containing the active coil sides and toroidal-shaped inner and outer ring portions formed by the inner and outer head turn portions respectively for the coil structure. The inner and outer toroidal-shaped ring portions are divided into a plurality of complementary, annular helically-shaped segments that are fitted together to form the complete coil structure having toroidal-shaped inner and outer circumferential ring portions, which define the inner and outer circumferential edges, respectively, of the discoidal winding, separated by the annular disc portion containing the active coil sides. In a preferred arrangement each complementary, annular, helically-shaped segment is itself divided into a number of arcuate sections with each arcuate section having input and output leads that may be electrically interconnected with the leads of adjacent arcuate sections physically juxtaposed to form a complete annular, helically-shaped segment.
