AbstractThe polyphase stator winding of a dynamoelectric machine consists of a plurality of coils circumscribed about one another. Each coil has at least one end turn which includes two coil sides and a C-shaped connector ring that joins the coil sides together. The coil sides are straight conductors, or ones that are slightly bent on each end, and are embedded within the stator slots and extend into the end basket region of the machine where they are joined together by the C-shaped connector rings.
