  • Rotor assembly
    Patent number: 11381142
    Abstract: A rotor assembly for an electric machine includes a cylindrical rotor core, a set of posts extending radially outward from the rotor core defining a set of slots between adjacent posts, a set of windings formed by conductive wire wound in the set of slots having end turns extending axially beyond the rotor core, and a retention case overlying the end turns.
    Type: Grant
    Filed: March 11, 2019
    Date of Patent: July 5, 2022
    Assignee: GE Aviation Systems LLC
    Inventors: John S. Mears, Austin Michael Cobert, Todd Eric Rook
  • Method and assembly of a stator sleeve
    Patent number: 11128201
    Abstract: A stator sleeve assembly for an electric machine includes a first cylindrical housing portion defining an inner radial cavity defined by at least one circumferential wall and an outer radial cavity, and a set of radial passages fluidly connecting the inner radial cavity with the outer radial cavity, and a second cylindrical housing portion defining a third cavity, the second housing portion axially spaced from the first housing portion.
    Type: Grant
    Filed: September 6, 2017
    Date of Patent: September 21, 2021
    Assignee: GE Aviation Systems LLC
    Inventors: Pradeep Hemant Sangli, Santosh Kumar Prasad, Todd Eric Rook
  • Stator assembly
    Patent number: 10833543
    Abstract: A stator core and method of forming a stator assembly for an electric machine, including a cylindrical stator core, a set of posts extending radially inward from the stator core defining a set of slots between adjacent posts, and a set of windings formed by conductive wire wound in a fewer than all of the set the slots, defining a first subset of wound slots and a second subset of empty slots.

  • Stator support for an electric machine
    Patent number: 10819182
    Abstract: A stator support 40 for an electric machine 10 includes a radial cut 70 in a support ring 46 that releases hoop stress in the support ring 46 and enables more radial displacement during heating and cold soak cycles in the stator 12, 16, thereby allowing a larger range of thermal conditions for the electric machine 10.
