Title: ROTATING ELECTRICAL MACHINE WITH OPTIMIZED COOLING
Abstract:
The invention relates to a rotating electrical machine that includes a shaft (13); a rotor (12) mounted on the shaft; a stator (16) surrounding the rotor, said stator having a body (25) provided with slots and a winding (26) inserted into the slots, the winding having visible portions (27) extending on either side of the body, said visible portions comprising, at their base, openings (30) extending between conductors of the winding leaving the slots in the body; and a first bearing (37) and a second bearing (38) surrounding an assembly formed by the rotor and the stator and each including a housing (40, 44) for rotatably mounting the rotor shaft. The first bearing includes a contact area (Z1) on the body and at least one aperture (551, 552) located radially at least partially opposite at least one opening (30) in one of the visible portions.
