Patent ID: 7741587

Claim:
A method of forming a brazed joint between an armature bar and a hydraulic header clip comprising: a) assembling free ends of hollow strands and of solid strands of the armature winding bar and positioning the assembly within the hydraulic header clip; b) interleaving a silver based braze alloy 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; c) positioning the assembly of the free ends, hydraulic header clip and the braze alloy in a braze chamber, such that the clip is seated in an induction heating coil of the chamber; d) heating the assembly to a first temperature below a solidus temperature of the braze alloy and within a 200 degrees Fahrenheit of the solidus temperature by activating the induction heat coil to heat the clip; e) heating the assembly to a second temperature above the liquidus temperature of the braze alloy; f) pooling liquid braze alloy on ends of the armature bar, and g) cooling the assembly and clip thereby forming a braze isolation layer on the end of the armature bar.
