Abstract

L'invention propose un circuit magnétique comportant un empilement annulaire (22) de tôles (12), chaque tôle (12) comporte une couronne (14) une pluralité de branches (16), caractérisé en ce que l'empilement de tôles comporte : - un groupe de tôles primaires (52) dont une branche de raccordement (16) est globalement en forme de L qui s'étend axialement dans un premier sens) ; et - un groupe de tôles secondaires (54) dont une branche de raccordement (16) est en forme de U ou en forme de L qui s'étend axialement dans un deuxième sens opposé audit premier sens.The invention proposes a magnetic circuit comprising an annular stack (22) of sheets (12), each sheet (12) comprises a ring (14) and a plurality of branches (16), characterized in that the stack of sheets comprises: - a group of primary sheets (52), a connecting branch (16) of which is generally L-shaped which extends axially in a first direction); and - a group of secondary sheets (54) of which a connecting branch (16) is U-shaped or L-shaped which extends axially in a second direction opposite to said first direction.
