Abstract
An electric generator longitudinally extends along a longitudinal axis between a drive end and an opposite non-drive end. The electric generator includes a stator having: a stator body including a stator yoke and a plurality of teeth protruding according to a radial direction orthogonal to the longitudinal axis from the stator yoke to respective tooth radial ends, each tooth extending longitudinally between the drive end and the non-drive end, a stator support for radially supporting the stator body, the stator support further providing an axial support to the stator body at the non-drive end, an end plate for axially supporting the stator body at one of the drive end or the non-drive end.

An electric generator longitudinally extending along a longitudinal axis between a drive end and an opposite non-drive end, the electric generator comprising a stator having:
- a stator body including a stator yoke and a plurality of teeth protruding according to a radial direction orthogonal to the longitudinal axis from the stator yoke to respective tooth radial ends, each tooth extending longitudinally between the drive end and the non-drive end, and
- a stator support located radially inward of the stator body for radially supporting the stator body, the stator support further providing an axial support to the stator body at the non-drive end, wherein the axial support is provided by a shoulder extending longitudinally past a non-drive end of the stator body, protruding radially outward from the stator support, and extending around a circumferential distance of the stator support,
- wherein the stator further comprises an end plate for axially supporting the stator body at the drive end, wherein the end plate is finger-shaped, wherein the end plate includes a plate yoke adjacent to the stator yoke and a plurality of plate teeth protruding from the plate yoke according to the radial direction, and wherein each plate tooth of the plurality of plate teeth is adjacent to a respective stator tooth of the plurality of teeth of the stator body.
A stator for an electric generator comprising:
- a stator body including a stator yoke and a plurality of teeth protruding according to a radial direction orthogonal to the longitudinal axis from the stator yoke to respective tooth radial ends, each tooth extending longitudinally between a first end and a second opposite end, and
- a stator support located radially inward of the stator body for radially supporting the stator body, the stator support further providing an axial support to the stator body at one of the first end and the second opposite end, wherein the axial support is a shoulder extending longitudinally past the respective one of the first end and the second opposite end, protruding radially outward from the stator support, and extending around a circumferential distance of the stator support,
- wherein the stator further comprises an end plate for axially supporting the stator body at the other of the first end and the second opposite end, wherein the end plate is finger-shaped, wherein the end plate includes a plate yoke adjacent to the stator yoke and a plurality of plate teeth protruding from the plate yoke according to the radial direction, and wherein each plate tooth of the plurality of plate teeth is adjacent to a respective stator tooth of the plurality of teeth of the stator body.
