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.

A liquid cooled alternator comprising a casing, one end of which is closed by a rear bearing which carries a rectifier bridge for rectifying the alternating current produced by the alternator, the bearing having an internal cavity in which a coolant liquid flows. The bearing is formed with at least one chimney element which is open axially at both axial ends of the bearing. These chimney elements extend through the internal cavity of the bearing, so that an outer face of a side wall of the chimney element is in contact with the coolant liquid flowing in the cavity. At least one component of the rectifier bridge is mounted within at least one corresponding chimney element.
