Abstract

L'invention concerne un outil électrique comprenant une culasse généralement cylindrique (31), plusieurs aimants (32) fixés à travers un espace circonférentiel à la circonférence intérieure de la culasse (31), une armature (41) placée de façon rotative sur le côté intérieur de la culasse (31) à travers un espace radial situé entre la culasse (31) et les aimants (32), et un pare-poussière (33) inséré dans une extrémité axiale de la culasse (31). Le pare-poussière (33) possède plusieurs saillies (33b) s'engageant avec l'espace circonférentiel situé entre les aimants (32) dans la culasse (31).
