ABSTRACT:
An improved end turn construction to improve cooling in a dynamoelectric machine and to axially reduce the size thereof. The machine includes a body (12) of magnetizable material having opposed ends (18) an opening (14) extending between the ends and the plurality of slots (50) about the opening (14). A rotor (16) is disposed within the opening (14) and journalled for rotation therein and electric conductors (52) are located in the slots (50) and extend to ends (54, 56) just past the ends (18) of the body (12). End turns (58, 60, 68) each interconnect a predetermined pair of the conductors (52) and extend substantially circumferntially and radially of the rotor axis with no appreciable extension axially of the axis.
