Abstract
(EN) End face plates (114) are arranged at both end faces of a circular body constituted by annularly arranging permanent magnets (110) and rotor cores (111). The end face plates (114) are integrally formed by shrink-fitting a nonmagnetic annular disk (112) and a ring member (113) having a linear expansion coefficient smaller than the annular disk (112) provided in contact with the inner periphery of the annular disk (112). An embedded magnet-type rotor is formed by press-fitting a shaft (109) having the same linear expansion coefficient as that of the ring member (113) into a hollow part formed by the inner periphery of the ring member (113) that defines a center hole (118) of the end face plates (114).
(FR) L'invention porte sur des plaques de face d'extrémité (114), qui sont disposées aux deux faces d'extrémité d'un corps circulaire constitué par des aimants permanents disposés de façon annulaire (110) et par des noyaux de rotor (111). Les plaques de face d'extrémité (114) sont formées d'une seule pièce par emmanchement à chaud d'un disque annulaire non-magnétique (112) et d'un élément d'anneau (113) ayant un coefficient de dilatation linéaire inférieur à celui du disque annulaire (112) et placé en contact avec la périphérie intérieure du disque annulaire (112). Un rotor du type à aimants encastrés est formé par emmanchement à la presse d'un arbre (109) ayant le même coefficient de dilatation linéaire que l'élément d'anneau (113) dans une partie creuse formée par la périphérie intérieure de l'élément d'anneau (113) qui définit un trou central (118) des plaques de face d'extrémité (114).
(JA)  永久磁石(110)と回転子コア(111)とを環状に配置して成る磁石及びコアの環状体の両端面に設置された端面板(114)が、非磁性の環状円板(112)と、環状円板(112)の内周に接して設けられた環状円板(112)より線膨張係数が小さいリング部材(113)とを、焼きばめで一体化して形成されており、端面板(114)の中心孔(118)になっているリング部材(113)の内周側の中空部にリング部材(113)と同じ線膨張係数のシャフト(109)が圧入されて形成されている。
