  • Patent number: 6784573
    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.

  • Patent number: 5831511
    Abstract: A resistance temperature detector (RTD) unit includes an RTD assembly that is removably supported in a central chamber of a support assembly. In a preferred arrangement, the RTD assembly and the central chamber are arc shaped to facilitate removal from the support assembly and to maintain contact surface area. By providing a removable RTD assembly, costs are reduced over current RTD assemblies including two monitoring elements, and the RTD elements can be replaced without dismantling the top bar connections.

  • Patent number: 5796189
    Abstract: A method of creating a brazed joint between a plurality of solid and hollow strands of a stator bar and a stator bar end fitting comprising the steps of:a) inserting between free ends of the plurality of solid and hollow strands a preformed braze alloy such that the braze alloy is at least flush with the free ends of the hollow and solid strands;b) applying stop off material to free end edges of at least the hollow strands;c) inserting the solid and hollow strands and preformed braze alloy in an opening of a stator bar end fitting;d) heating the braze alloy to cause the braze alloy to flow about and between the solid and hollow strands and between the fitting and the solid and hollow strands, but wherein the stop off material prevents flow of braze alloy onto the free end edges of the hollow strands.
