End turn construction for dynamoelectric machines

Claim 1

A dynamoelectric machine comprising: a body of magnetizable material having opposed ends, an opening extending between said ends and plurality of slots about the opening; a rotor within said opening and journalled for rotation therein about an axis; electrical conductors constituting windings for said machine and located in said slots and extending therefrom just past said ends; electrical conductive end turns adjacent each of said ends, each interconnecting a predetermined pair of said conductors, said end turns being shaped as a series of stretched, interwoven "Z's" each connected at its respective ends to said electrical an associated one of a corresponding pair of conductors, tops and bases of said Z shaped series defining closely adjacent, parallel planes transverse to said axis and being concave with respect to said axis; a radially extending baffle disposed between said tops and said bases; and means for flowing coolant into said series in a generally radially inward direction on one side of said baffle and in a generally radially outward direction on another side of said baffle.
