Abstract
The invention relates to a flange (1) for an electrical machine (100), said flange being configured to at least partially cover winding overhangs (10) that form part of the electrical machine (100), the flange (1) comprising a chamber (5) able to receive a cooling fluid, characterized in that the flange (1) comprises at least one first orifice and at least one second orifice allowing cooling fluid to enter the chamber (5) or allowing cooling fluid to leave the chamber (5), said chamber (5) having a profile that compliments that of at least one winding overhang (10). Said invention is applicable to motor vehicles.
Claims14
A flange for an electrical machine configured to at least partially cover winding overhangs that form part of the electrical machine, the flange defining an axis, an axial inner surface, an axial outer surface, and an outer peripheral face;
- said flange comprising:
- a chamber able to receive a cooling fluid, wherein the flange comprises at least one first orifice and at least one second orifice allowing cooling fluid to enter the chamber or allowing the cooling fluid to leave the chamber, said chamber being defined by surfaces which in turn define at least one accommodation sized to receive at least one winding overhang;
- said accommodation having a profile complementary to that of the at least one winding overhang;
- and wherein said chamber is configured to be leakproof so as to substantially prevent the cooling fluid from contacting the at least one winding overhang.
A flange for an electrical machine configured to at least partially cover winding overhangs that form part of the electrical machine, the flange comprising a chamber able to receive a cooling fluid, wherein the flange comprises at least one first orifice and at least one second orifice allowing cooling fluid to enter the chamber or allowing the cooling fluid to leave the chamber, said chamber having a profile complementary to that of at least one winding overhang;
- wherein the chamber is delineated by two semi-disks between which extends a semi-circular bottom in such a way as to delineate at least one accommodation that complements at least one winding overhang.
A flange for an electrical machine configured to at least partially cover winding overhangs that form part of the electrical machine, the flange comprising a chamber able to receive a cooling fluid, wherein the flange comprises at least one first orifice and at least one second orifice allowing cooling fluid to enter the chamber or allowing the cooling fluid to leave the chamber, said chamber having a profile complementary to that of at least one winding overhang, wherein the flange comprises a ring which encircles an inner part of the flange and delineates at least partially the chamber.
