  • Rotary electric machine, and in particular motor vehicle alternator, comprising a stator elastically mounted in a heat-conductive resin
    Patent number: 6798094
    Abstract: A rotary electrical machine (10), especially a motor vehicle alternator, having a stator (12) of generally cylindrical annular form, which is arranged in a casing (14) having a rear portion (16) and a front portion (18) in which the outer axial face (24) of the stator (12) and the inner axial face (30) of the casing (14) define an annular radial space (32), and the stator (12) is suspended elastically within the casing (14), wherein at least part of the annular radial space (32) contains thermally conductive resin (50) which is deformable axially and interposed radially between the casing (14) and stator (12), so as to effect radial mechanical decoupling between the stator (12) and casing (14) and so as to dissipate heat energy from the stator (12) to the casing (14).

  • Rotary electric machine, and in particular motor vihicle alternator, comprising a stator elastically mounted in a heat-conductive resin
    Publication number: 20030020338
    Abstract: The invention proposes a rotary electrical machine (10), especially a motor vehicle alternator, of the type comprising a stator (12) of generally cylindrical annular form, which is arranged in a casing (14) comprising a rear portion (16) and a front portion (18), of the type in which the outer axial face (24) of the stator (12) and the inner axial face (30) of the casing (14) delimit an annular radial space (32), and of the type in which the stator (12) is suspended elastically within the casing (14), characterized in that at least part of the annular radial space (32) contains thermally conductive resin (50) which is deformable axially and interposed radially between the casing (14) and stator (12), so as to effect radial mechanical decoupling between the stator (12) and casing (14) and so as to dissipate heat energy from the stator (12) to the casing (14).
