Abstract

a. Moteur électrique comportant au moins un balai appliqué sur un collecteur par un ressort spiral 24, dont l'extrémité intérieure est dirigée vers le centre d'enroulement du ressort, pour être insérée parallèlement à la direction de l'axe d'enroulement du ressort dans une fente 22 à bouts ouverts d'une saillie 18 qui s'étend elle-même parallèlement à cet axe d'enroulement. b. Moteur caractérisé en ce que la profondeur d'enfichage 23 de la fente 22 est, parallèlement à l'axe d'enroulement, plus grande que la largeur 32 de l'extrémité intérieure 26 du ressort, la fente 22 présentant au moins une dépouille arrière 38 sur une hauteur 39 adaptée à la largeur 32 de l'extrémité du ressort 22, mesurée à partir d'une butée d'enfichage 34 de l'extrémité 22. c. Dispositif de balais applicable à un moteur électrique.at. Electric motor comprising at least one brush applied to a collector by a spiral spring 24, the inner end of which is directed towards the center of winding of the spring, to be inserted parallel to the direction of the axis of winding of the spring in a slot 22 with open ends of a projection 18 which itself extends parallel to this winding axis. b. Motor characterized in that the insertion depth 23 of the slot 22 is, parallel to the winding axis, greater than the width 32 of the inner end 26 of the spring, the slot 22 having at least one rear relief 38 over a height 39 adapted to the width 32 of the end of the spring 22, measured from a plug-in stop 34 of the end 22. c. Brush device applicable to an electric motor.
