Patent

CA 2215208

In the motor armature arrangement according to the present invention, because the inner diameter (D2) of one of the axially end portions (3c) of the armature shaft (3) is reduced from the inner diameter (D1) of the motor core mounting portion (3b), the one axially end portion (3c) for a bearing (8b) may be provided with a large wall thickness so that a sufficient mechanical strength can be achieved for the part for mounting the bearing without increasing the outer diameter thereof.

Dans une structure d'induit pour moteur, le diamètre interne (D2) de l'extrémité (3c) d'un arbre d'induit cylindrique (3) est inférieur au diamètre interne (D1) d'un élément de fixation (3b) du noyau du moteur. De ce fait, l'épaisseur est accrue et on est assuré d'obtenir un élément de fixation du palier ayant une robustesse suffisante sans accroître le diamètre externe de l'extrémité (3c) de l'arbre (3) qui est un élément de montage du palier (8a).
