At least a part of the annular radial space (32) contains some of the elastically deformable thermal conducting resin (50). The resin is radially inserted between the casing (14) and the stator (12) so as to produce radial mechanical decoupling between the stator and the casing so as to dissipate thermal energy from the stator towards the casing. Only the front part (18) of the casing contains the resin. The alternator (10) is of the type having a rotor (13), cylindrical annular stator (13), surrounding the rotor, fitted into a casing (16). Front (18) and rear (16) parts of the casing are connected together along a joint plane (P) perpendicular to the axis X-X of the rotor. The external axial face (24) of the stator delimits with the axial internal face (30) of the casing an annular radial space (32) in which the stator is mounted and axially clamped between opposite radial surfaces (36,48) formed in each two parts (16,18) of the casing. An elastically deformable part (34,46) is compressed axially between each of the two support surfaces (34,48) and a part of the end annular radial face (20,22) opposite to the stator. The elastically deformable annular flat joint (46) is axially inserted between the radial face (22) of the stator and the support surface (48) formed in the front part (18) of the casing.
