Abstract

Dans un embrayage (10) doté d'un électro-aimant fixe (46) destiné à coupler un induit (56) à un rotor (12), le rotor présente des parties cylindriques intérieure et extérieure (14, 24) connectées à une extrémité par une partie d'embrayage annulaire (16) comportant des fentes arquées intérieure et extérieure (18, 22) qui traversent la partie d'embrayage (16) en partant d'emplacements radiaux situés au niveau de la surface d'embrayage (60) pour aboutir à des emplacements radiaux plus proches se trouvant de l'autre côté de la partie (16). La partie (24) peut présenter sur sa surface extérieure soit une gorge polytrapézoïdale (42), soit une gorge trapézoïdale (472), ou encore une denture (166).
