  • Patent number: 9455613
    Abstract: A winding for a rotor for use in an electrical generator utilized in the power generation industry. The winding includes a plurality of axial sections and a plurality of transversely oriented end arc sections. An integrated leg section extends from each end arc section to form an associated corner section at an intersection of each leg section and associated end arc section. Each leg section is affixed to an associated axial section at a joint that is spaced apart from an associated corner section such that the joint is not subjected to stress concentration which occurs at the associated corner section.
    Type: Grant
    Filed: July 8, 2014
    Date of Patent: September 27, 2016
    Assignee: SIEMENS ENERGY, INC.

  • Patent number: 8541916
    Abstract: A system for securing a nut (24) used to compress a compliant seal (23) surrounding a radial conductor lead (21) of an electric generator (10). The generator has a rotor (11) with the radial conductor lead arranged in a radial lead bore (20) of the rotor and the seal coaxially arranged surrounding the radial lead. A receiving pocket (15) is arranged in a body of the rotor adjacent to the radial lead bore. The nut is arranged coaxially with the radial conductor lead, the nut including a seal contacting surface (35) and a ligament (26) arranged opposite the seal contacting surface, wherein a portion of the ligament is deformed into the receiving pocket to lock the nut against rotation, thereby maintaining a desired degree of compression on the seal.

  • Patent number: 7119462
    Abstract: An interconnecting assembly (100) for a rotor assembly of a dynamoelectric machine is provided. The interconnecting assembly may be part of an electrically conductive path generally extending from a radially inward section of the rotor assembly to a top winding of a stacked winding (128) located at a radially outward section of the rotor assembly. The interconnecting assembly may include a first connecting member (106) connected to a radial lead (104) at the inward section of the rotor assembly. This first connecting member is made up of multiple conductive leaves and includes a flexible bend (108) positioned to provide a resilient-connection relative to at least a radial direction. The interconnecting assembly may further include a second connecting member (124) mechanically connected to the first connecting member by way of the resilient connection. This second connecting member is electrically connected to the first connecting member and to the top winding.
