  • Patent number: 8736129
    Abstract: An example end cap of a stator segment is provided for use in locating wires in a segmented stator assembly in desired positions. The end cap generally includes a body and an inboard wall. An identifier is defined by the inboard wall of the end cap for use in determining wire sizes to be used with the end cap. Terminal pockets are provided in the body for receiving the wires and making desired electrical connections, and steps located in the terminal pockets help secure the connectors in the terminal pockets. Plateaus, and troughs defined in the plateaus, are located outside the terminal pockets for use in trimming wires received in the terminal pockets as desired. And, retaining structures are located around the end cap to help with locating the wires in the desired positions.

  • Patent number: 8736130
    Abstract: Segmented stator assemblies having a plurality of stator segments and a plurality of end caps are disclosed. According to one example embodiment, a segmented stator assembly includes a plurality of stator segments and a plurality of end caps. Each stator segment has a yoke portion and a tooth portion extending from the yoke portion. Each end cap is positioned over one of the stator segments. Each end cap includes a body portion positioned at least partially over the yoke portion of its associated stator segment. At least one of the body portions includes at least a first post that cooperates with a post of an adjacent end cap to define a first wire management tie-down. The stator assembly further includes a stator wire coupled to the first wire management tie-down. Stator assemblies and end caps having other wire management and routing features are also disclosed.

  • Patent number: 7586231
    Abstract: A stator for an electromagnetic machine includes a plurality of discrete and individually wound stator segments having end caps positioned on the segments. The end caps have legs for positioning the end cap on the segments with an interference fit. The end caps have angled surfaces to facilitate winding of wire on the segments. The end caps have male and female couplings that mate together to couple adjacent segments together. The end caps have fingers and slots for aligning the segments on substantially the same plane. The end caps have wire isolation features, including hooks, shelves and ledges, for separating the interconnect wires routed on the stator to electrically interconnect the segments. The segments include scalloped contours on their outer edges for draining oil, and the end caps have passages for draining oil.

  • Patent number: 7578047
    Abstract: A method of stitching a plurality of interconnect wires on a stator of an electromagnetic machine is disclosed. The stator includes a plurality of discrete and individually wound stator segments having end caps positioned on the segments. The end caps have wire isolation features, including hooks, shelves and ledges, for separating the interconnect wires routed on the stator to electrically interconnect the segments. The method includes routing the interconnect wires between portions of the stator such that portions of the interconnect wires overlap and separating the overlapping portions in an axial direction with the wire isolation elements.
