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).
