Abstract
A stator assembly for an electrical machine extends azimuthally around an axis. The assembly includes: a plurality of stator teeth projecting radially from a circumference of the stator assembly, wherein the teeth are spaced azimuthally from each other and extend along a direction parallel to the axis of the stator assembly; a plurality of slots defined by azimuthal spacing of the stator teeth, wherein the plurality of slots extends along a direction parallel to the axis of the stator assembly, wherein the slots are arranged to receive a plurality of stator windings; and one or more dividers positioned within the plurality of slots, wherein the dividers define a plurality of cavities for receiving the plurality of stator windings.

A stator assembly for an electrical machine, wherein the stator assembly extends azimuthally around an axis, wherein the stator assembly comprises:
- a plurality of stator teeth projecting radially from a circumference of the stator assembly, wherein the teeth are spaced azimuthally from each other and extend along a direction parallel to the axis of the stator assembly;
- a plurality of slots defined by azimuthal spacing of the stator teeth, wherein the plurality of slots extends along a direction parallel to the axis of the stator assembly, wherein the slots are arranged to receive a plurality of stator windings;
- and
- one or more dividers positioned within the plurality of slots, wherein the dividers define a plurality of cavities for receiving the plurality of stator windings, wherein the divider is T-shaped comprising a body portion and an end portion;
- wherein the stator assembly further comprises one or more end-cheeks;
- wherein the one or more end-cheeks comprise one or more grooves arranged to receive the end portions of the one or more dividers.
A method of assembling a stator assembly for an electric machine, the method comprising:
- providing a plurality of stator teeth projecting radially from a circumference of the stator assembly,
- wherein the teeth are spaced azimuthally from each other and extend along a direction parallel to the axis of the stator assembly,
- wherein the azimuthal spacing of the plurality of stator teeth defines a plurality of slots, and
- wherein the plurality of slots extends along a direction parallel to the axis of the stator assembly;
- providing an end cheek on at least one end of the stator, wherein the one or more end-cheeks comprise one or more grooves formed on a face of the end cheeks;
- positioning one or more dividers within the plurality of slots, wherein the dividers define a plurality of cavities, wherein the one or more dividers are T-shaped comprising a body portion and an end portion and positioning includes positioning the end portions in the one or more grooves;
- and
- inserting a plurality of stator windings into the plurality of cavities, before, during or after the positioning of the one or more dividers,
- wherein the plurality of dividers substantially separates the plurality of stator windings.
