Abstract: The disclosure relates to a rotating electrical machine (1), in particular an alternator or an alternator-starter for a motor vehicle. At least one bearing mount (48) is provided with at least one opening (49) opening onto the exterior of the bearing mount. A stator (16) comprising an electric coil (18) is provided. This coil includes a plurality of electric conductors, at least one of which includes an end forming an electrical neutral point of the coil. The machine further includes an electrical insulation member (70) configured to prevent any contact between the bearing mount (48) and said neutral point-forming conductor end. The insulation member extends at least partially through the opening of the bearing mount and is at least partially outside the bearing mount. The electrical insulation member being furthermore configured to rest at least partially on an outer surface (71) of the bearing mount.
