Abstract

L'invention concerne un moteur électrique (10) équipé de balais (12) pour la commutation et d'un composant d'antiparasitage électrique (14). Les balais (12) sont disposés dans un porte-balais annulaire (18) qui repose sur une extrémité axiale (22) d'une partie formant carcasse (24), de préférence une carcasse polaire (240), du moteur électrique (10). Le composant d'antiparasitage (14) est disposé radialement à l'extérieur de la carcasse (24). Le porte-balais (18) comporte un prolongement (30) qui s'étend vers l'extérieur dans le sens radial (2), de sorte que ledit prolongement (30) s'étend à l'extérieur de la carcasse (24), et le composant d'antiparasitage (14) est disposé sur le prolongement (30).
