Abstract
A dynamoelectric machine utilizing stiff, multiple component phase leads for connecting potentially misaligned stator coils and parallel phase rings. The phase leads, when attached to stator coil and phase ring coolant headers, provide electrical communication therebetween. The first and second phase lead components have a hole and cylindrical portion respectively wherein the cylindrical portion is insertable in the hole. Such phase lead hole has a longitudinal axis perpendicular to both slot elongation directions. Intimate electrical contact between the phase lead components and their connected coolant headers is insured by disposidng solder between their mateable, plane surfaces. Intimate electrical contact between the phase lead components is insured by brazing the components together at the interface between the assembled cylindrical portion and hole. Translational misalignment between the connectable phase ring and coil is accommodated in the three perpendicular directions by providing the slotted openings and permitting insertion of the cylindrical phase lead portion into the phase lead hole for selected distances. Such selective insertion is obtained by supplying extra stock to the cylindrical phase lead portion and trimming that portion to the appropriate length at assembly time.
