Abstract
An end ring assembly for a rotor, wherein the rotor is rotatable about a central longitudinal axis, includes a plurality of annular sheets stacked adjacent one another. Each of the plurality of annular sheets has a first surface and a second surface spaced opposite the first surface. The end ring assembly also includes a braze material sandwiched between and joining only a first portion of the first surface of each of the plurality of annular sheets, and a corresponding second portion of the second surface of a respective adjacent one of the plurality of annular sheets without joining an entirety of the first surface of each of the plurality of annular sheets and the second surface of the respective adjacent one of the plurality of annular sheets. A method of forming the end ring assembly is also disclosed.
