ROTARY ELECTRIC MACHINE STATOR
First Claim
1. A rotary electric machine stator comprising:
- a stator body; and
a stator winding supported by the stator body,wherein the stator body is formed by a core of stacked laminations and extends around an axis while being delimited by an internal radial surface and an external radial surface,said stator body having a plurality of teeth formed respectively between two slots arranged in said stator body from the internal radial surface and extending axially to receive at least one stator winding element, so that along the circumference of the stator the latter has an alternation of slots and teeth,wherein the plurality of teeth comprise at least one deformed tooth having, at a loose end helping to define the internal radial surface of the stator, at least one protrusion extending across at least one adjacent slot, said protrusion being obtained by material deformation of said deformed tooth, andwherein said protrusion is formed by a bead resulting from displacement of material in the deformed tooth, from the external radial surface of the stator towards the internal radial surface of the stator.

Abstract
A rotary electric machine stator (2) includes a stator body (20) and a stator winding (22) supported by the stator body (20), in which the stator body extends around an axis (X) while being delimited by an internal radial surface (3) and an external radial surface (4), said stator bodies having a plurality of teeth (6) formed respectively between two slots (5) arranged in said stator body from the internal radial surface and extending axially to receive at least one stator winding element (22).
The stator has at least one deformed tooth (6) which comprises, at its loose end (7) helping to define the internal radial surface, at least one protrusion (10) extending across an adjacent slot, said protrusion (10) being obtained by material deformation of said deformed tooth (6).
