Abstract
A stator assembly for a dynamoelectric machine featuring a cascaded construction includes several conductors, each having a plurality of slot segments interconnected by plurality of end loop segments. The consecutive slot segments of a first conductor forms nearly all of a radially-outermost first layer of the stator winding, with the remaining portion of the radially-outermost winding layer being defined by a slot segment of a second conductor that is then inserted into the core to form nearly all of a second layer of the stator winding radially-inwardly of the first winding layer. The second winding layer is completed with an additional single slot segment of the first conductor.
