Patent ID: 7405379

Claim:
A system for forming a brazed joint between an armature winding bar and a hydraulic header clip comprising: an assembly of free ends of hollow strands and solid strands of the armature winding bar positioned within the hydraulic header clip; a silver based braze alloy interleaved between the strands, wherein a portion of the braze alloy extends axially beyond the free ends of a plurality of the solid strands and the free ends of a plurality of the hollow strands extend axially beyond the braze material; said assembly of the free ends, hydraulic header clip and the braze alloy mounted in a braze chamber, such that the clip is seated in an induction heating coil of the chamber, and a controller receiving a temperature feedback signal from a temperature sensor in the chamber and controlling a temperature in the chamber by controlling power applied to the coil and based on the feedback signal, wherein during a brazing period said coil heats the assembly to a temperature above the liquidus temperature of the braze alloy.
