An electrical rotating machine includes a stator () provided with teeth () around which a group of coils () is wound, an annular interconnector () resting on a stator lamination stack () provided with tongues () to which ends () of the coils () are welded for the formation of phases (U, V, W) of the electrical machine, and a closure flange () for closing a housing () for receiving the stator (). The machine also includes at least one damper () consisting of a deformable material, configured to be mounted so as to be compressed between the interconnector () and the closure flange () of the machine. The invention also relates to the corresponding damper.

Electrical machine with damper to resist vibratory stresses mechanically, and corresponding damper

A rotary electrical machine ( ), especially a motor vehicle alternator, having a stator ( ) of generally cylindrical annular form, which is arranged in a casing ( ) having a rear portion ( ) and a front portion ( ) in which the outer axial face ( ) of the stator ( ) and the inner axial face ( ) of the casing ( ) define an annular radial space ( ), and the stator ( ) is suspended elastically within the casing ( ), wherein at least part of the annular radial space ( ) contains thermally conductive resin ( ) which is deformable axially and interposed radially between the casing ( ) and stator ( ), so as to effect radial mechanical decoupling between the stator ( ) and casing ( ) and so as to dissipate heat energy from the stator ( ) to the casing ( ).
