Abstract

L'invention porte principalement sur une machine électrique tournante (10), notamment pour véhicule automobile, comportant: - un stator (11), - un rotor (12) comportant: - un corps (28) comportant au moins une cavité (30), - au moins un aimant permanent (29) disposé dans la cavité, caractérisée en ce qu'une couche de résine (38) polymère recouvre au moins une face de l'aimant permanent (29) de sorte à être interposée entre ladite face de l'aimant permanent (29) et une face interne de la cavité (30).The invention relates mainly to a rotary electrical machine (10), in particular for a motor vehicle, comprising: - a stator (11), - a rotor (12) comprising: - a body (28) comprising at least one cavity (30) , - at least one permanent magnet (29) arranged in the cavity, characterized in that a layer of polymer resin (38) covers at least one face of the permanent magnet (29) so as to be interposed between said face of the permanent magnet (29) and an internal face of the cavity (30).
