The invention relates mainly to a rotary electric machine for a motor vehicle. The machine () comprises a shaft (); a rotor (); a stator () comprising a body () provided with slots, and a winding () inserted into the slots; a first bearing () and a second bearing () surrounding an assembly formed by the rotor and the stator and each comprising a housing () for rotatably mounting the rotor shaft (). The first bearing comprises a transverse flange () and a cylindrical wall () of axial orientation derived from an outer periphery of said flange. The second bearing comprises a transverse flange () closing the first bearing and at least one rim () projecting from the flange and forming a junction area () where it joins the first bearing. Furthermore, the stator body has a region (Z) of shrink-fitting to the cylindrical wall.

Rotary electric machine with shrink-fitted bearing

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