Abstract: An end shield for a rotary electric machine includes a plate which extends generally transversely in relation to an axis (X), and a skirt which extends generally axially from the plate. The skirt has at least one shoulder which forms an axial stop, the shoulder being intended to axially block a stator body of the rotary electric machine. The shoulder extends only over a portion of the circumference of the skirt.

Abstract: The invention relates mainly to a rotary electric machine for a motor vehicle. The machine (10) comprises a shaft (13); a rotor (12); a stator (16) comprising a body (25) provided with slots, and a winding (26) inserted into the slots; a first bearing (37) and a second bearing (38) surrounding an assembly formed by the rotor and the stator and each comprising a housing (40, 44) for rotatably mounting the rotor shaft (13). The first bearing comprises a transverse flange (371) and a cylindrical wall (372) of axial orientation derived from an outer periphery of said flange. The second bearing comprises a transverse flange (48) closing the first bearing and at least one rim (63) projecting from the flange and forming a junction area (64) where it joins the first bearing. Furthermore, the stator body has a region (Z1) of shrink-fitting to the cylindrical wall.

Abstract: The fitting of a stator (13) body (14) equipped with a winding (12) in an inner support surface (250) for a skirt (155) of a bearing (15) of a rotary electrical machine, such as an alternator or an alternator-starter of a motor vehicle, characterized in that the skirt (155) is heated locally by induction before fitting of the body (14) equipped with its winding (12) in the skirt (155). The invention also relates to a rotary electrical machine comprising a fitting of this type.

Abstract: The invention relates to a stator (13) for an alternator or an electric machine, which comprises: a cylindrical hub (14) in which a plurality of slots (201) that extend in the axial direction are formed, and a coil (12) mounted in the slots; in which the stator core (14) comprises: a cylindrical base portion (203) forming a cylinder head (203), a plurality of teeth (202) arranged such as to extend from the base portion towards an axial center (X-X), the plurality of slots (201) being defined by the base portion and by an adjacent pair of the teeth (202). For each notch (201) the width at the opening of the notch (l_eo) is smaller than the width (l_ec) at the cylinder head (203).
