  • Patent number: 9509182
    Abstract: Embodiments of the invention relate generally to turbo-generators and, more particularly, to suspension systems for turbo-generators and the attenuation of vibration in a stator core induced by an electromagnetic load. In one embodiment, the invention provides a support clamp comprising: an arcuate body; a first affixation point; a second affixation point; and a securing point between the first and second affixation points, wherein each of the first and second affixation points includes a radially-oriented opening extending from an inner surface to an outer surface and the securing point includes an area adjacent to an angled opening extending from a first surface to a second surface, each of the first and second surfaces lying substantially perpendicular to the inner and outer surfaces of the arcuate body.

  • Patent number: 9263921
    Abstract: Embodiments of the invention relate generally to electromagnetic devices and, more particularly, to the compression of stator core laminations using wire rope members and to stator cores and electromagnetic devices employing such wire rope members. In one embodiment, the invention includes: affixing a first end of a wire rope member to a first flange plate disposed adjacent a first end of a plurality of stator laminations; affixing a second end of the wire rope member to a second flange plate disposed adjacent a second end of the plurality of stator laminations; tensioning at least one of the first end or the second end of the wire rope member against at least one of the first flange plate and the second flange plate to exert a compressive force against the first flange plate, the second flange plate, and the plurality of stator laminations.

  • Patent number: 7936103
    Abstract: A method for assembling an electric machine is provided. The method includes providing a rotor having a cavity formed therein. At least one contoured recess is formed in a portion of the cavity. A wedge is inserted into the cavity. The wedge includes at least one contoured protrusion that is configured to mirror the at least one contoured recess of the cavity. The wedge is inserted such that the at least one contoured protrusion is positioned within the at least one contoured recess to facilitate positioning the wedge within the cavity. The at least one contoured protrusion and the at least one contoured recess are shaped to facilitate minimizing stresses within the rotor and the wedge.
