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: An electronic assembly for a rotary electric machine for a motor vehicle is disclosed. The electronic assembly includes electronic component blocks having different thermal dissipation needs, the blocks including a power block and a control block. The assembly also includes a device for cooling the blocks and having a protective cover suitable for covering the power and control blocks. The protective cover includes a first set of openings configured to be positioned opposite a first cooling element coupled to the power block, and opposite the control block, the first cooling element being a first dissipator provided with a base plate, the base plate protruding with respect to the power block to create a first radial flow of cooling air (F1) for the power block and a second radial flow of cooling air (F2) for the control block.
