ABSTRACT:
An axial gap synchronous dynamoelectric machine consists essentially of a disc-shaped rotor having axially oriented permanent magnet pole bodies with faces lying in an annular surface; a stator core spaced axially from the pole faces; and a discoidal AC winding linked with the pole bodies and the core. The winding consists of a plurality of coils laid overlapping in an annular array and bonded together with a resinous material into a unitary structure having an annular disc portion containing the coil sides and inner and outer ring portions containing the coil end-heads. It is supported by the stator with its disc portion in the space between the stator core and the pole faces, and its disc portion is spaced axially from the pole faces.
