Abstract: The present invention relates to a motor vehicle rotary electric machine (100) drive assembly, the drive assembly comprising a rotor shaft (2) extending along a longitudinal axis (X) and a connecting piece (4) providing connection between the shaft and the torque transmission system comprising a bore (41) for the passage of the rotor shaft, the drive assembly being characterized in that the bore comprises a first wall (41a) extending axially and a cylindrical second wall (41b) extending axially in alignment with the first wall, and in that the rotor shaft comprises: —a first surface (21) extending axially and cooperating with the first wall of the bore to centre the connecting piece around the rotor shaft; and—a second cylindrical surface (22) extending axially and provided with knurling, with a diameter (A) greater than the diameter (A?) of the second wall of the bore, the connecting piece being force-fitted onto the rotor shaft by means of the knurling.

Abstract: A stator of a rotary electrical machine has a stator body formed by a stack of metal sheets. The stator body is delimited by inner and outer radial surfaces. Notches in the stator body extend axially. Each notch has a notch base and a notch opening, and the notch opening is on the side of the inner radial surface. A stator winding is supported by the stator body, and the winding has a plurality of winding parts. Each part is accommodated in one of the notches. Each of the notches at the notch opening has a closure element. Each winding par in a notch is retained between the notch base and the closure element. The closure elements are formed by offsetting at least one of the metal sheets of an adjacent notch in the direction of the notch.

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).
