The invention relates to a rotating electric machine, especially an alternator or alternator/starter for motor vehicles, including a stator surrounding a rotor (10) equipped with a pack of metal plates, a gap between the stator and the rotor, permanent magnets integrated into the rotor and excitation coils (14) integrated into the rotor, in which the excitation coils are wound around salient poles (1310) cut out in the pack of metal plates of the rotor, and the permanent magnets are accommodated in housings (13110) formed in the pack of plates of the rotor and open towards the periphery of the rotor, characterized in that the housings (13110) are closed axially at each of their ends by a non-magnetic retaining piece (13) equipped with a part intended to come into abutment with the magnets, and in that the retaining piece features recesses for accommodations [sic] of the buns of the excitation coils (14).
