Title (EN) ROTOR FOR SYNCHRONOUS MOTOR
(FR) ROTOR DE MOTEUR SYNCHRONE
Abstract: front page image
(EN)A rotor for a synchronous motor used for driving a machine tool or the like has a hollow field member (10) constituted by permanent magnets (11) and magnetic members (12) which are alternately disposed in the circumferential direction thereof. The field members (10) are disposed around the outer periphery of a shaft (16) formed of a magnetic material, with a gap (G) provided therebetween. Thus any leakage of magnetic flux penetrating the shaft (16) is reduced.
(FR)Un rotor de moteur synchrone utilisé pour entraîner une machine-outil ou une installation similaire possède un élément de champ creux (10) formé d"aimants permanents (11) et d"éléments magnétiques (12) disposés alternativement sur sa circonférence. Les éléments de champ (10) sont disposés autour de la périphérie extérieure d"un arbre (16) formé d"un matériau magnétique; un intervalle (G) les sépare. On réduit ainsi les pertes de flux magnétique pénétrant dans l"arbre (16).
