Abstract
A brazed joint between an armature bar strand package and an end fitting is provided where a plurality of solid strands and a plurality of hollow strands are arranged in an array. The plurality of hollow strands have free ends that extend axially beyond corresponding free ends of the solid strands. A cavity in the end fitting is accessed by an opening, and the free ends of the plurality of hollow and the corresponding free ends of the solid strands extend through the opening into the cavity. A braze alloy joins the free ends of the plurality of hollow strands and the corresponding free ends of the plurality of solid strands to each other and to interior surfaces of the end fitting, wherein the braze alloy does not extend substantially beyond the free ends of the solid strands. A related method of forming the brazed joint is also disclosed.
