Summary:Commutator (1) for a rotor (4) for a rotary electric machine, having a longitudinal axis (X-X) and comprising: - a lower collecting ring (10a) and an upper collecting ring (10b) which are separated from each other by a annular axial space, - a spacing ring (20) which is received in the annular axial space, - a lower line (16a) which is electrically connected to the lower collecting ring and an upper line (16b) which is electrically connected to the upper collecting ring, - a protection element (19) comprising an electrically insulating guiding zone (191b) which is arranged between the upper line (16b) and the lower collecting ring (10b), characterised in that the spacing ring (20) comprises at least one internal means (202) and the protection element (19) comprises at least one external means (196), the internal means cooperating with the external means so as to prevent the spacing ring from rotating relative to the protection element. Collecteur (1) de rotor (4) pour une machine électrique tournante, présentant un axe longitudinal (X-X) et comprenant : - une bague collectrice inférieure (10a) et une bague collectrice supérieure (10b), séparées l'une de l'autre par un espace axial annulaire, - une bague d'espacement (20) logée dans l'espace axial annulaire, - une trace inférieure (16a) connectée électriquement à la bague collectrice inférieure et une trace supérieure (16b) connectée électriquement à la bague collectrice supérieure, - un élément de protection (19) comportant une zone de guidage (191b) isolante électriquement et disposée entre la trace supérieure (16b) et la bague collectrice inférieure (10b), caractérisé en ce que la bague d'espacement (20) comporte au moins un moyen interne (202) et l'élément de protection (19) comporte au moins un moyen externe (196), le moyen interne coopérant avec le moyen externe de sorte à interdire la rotation de la bague d'espacement par rapport à l'élément de protection.
