Title: Dynamoelectric machine with air gap armature winding

Abstract: An air gap armature winding is provided for large generators. The armature winding preferably consists of conductors closely packed together in the air gap so that the maximum cross section of conductors can be used, and several radial layers of such conductors may be used. In order to permit forming the end portions of the winding conductors to the usual diamond or an equivalent) configuration, certain of the conductors lying at circumferentially spaced intervals are displaced radially in the end portions to make from for end turns to be formed. The displaced conductors are disposed so that the radial thickness of the end turn portions is not unduly increased.
