Abstract

L'invention vise à réduire la résistance magnétique entre des dents et une culasse. Une pluralité de dents (200) aménagées selon une forme annulaire sont formées individuellement par la stratification radiale de deuxièmes plaques magnétiques (202). Chaque dent (200) comprend un premier corps trapézoïdal (212) comportant un haut de partie inférieure, dans lequel une deuxième plaque magnétique (202) placée le plus près d'un axe, vu de dessus, présente une longueur (Ln) dans une première direction, et un fond de partie inférieure, dans lequel une autre deuxième plaque magnétique (202), placée dans une position radialement extérieure à celle d'une deuxième plaque magnétique (202) présente une longueur (Lf) (Ln < Lf) dans la première direction. Un premier bord latéral (208) de chacune des deuxièmes plaques magnétiques (202) constituant le premier corps trapézoïdal (212) est incurvé depuis le haut de la partie inférieure vers le fond de la partie inférieure.
