Abstract
(EN) The purpose of the present invention is to provide a dynamo-electric machine with which it is possible to inhibit vibration of a frame and a bearing, and which has excellent manufacturability. The dynamo-electric machine according to the present invention comprises: a stator (2); a rotor (1) disposed on the radially inner side of the stator (2), the rotor (1) being provided with a rotary shaft (10); a bearing (16) for supporting the rotary shaft (10); an intermediate frame (15) for supporting the stator (2); and a stator frame (8) for supporting the bearing (16) and the intermediate frame (15). The stator frame (8) comprises pedestals (83) at the two widthwise end sections of the bottom part thereof. The pedestals (83) each comprise an upper surface (83a) positoned higher than the bottom surface of the stator frame (8). The intermediate frame (15) is fixed to the upper surfaces (83a) of the pedestals (83).
(FR) L'objet de la présente invention est de produire une machine dynamoélectrique grâce à laquelle il est possible d'inhiber la vibration d'une armature et d'un palier, et dont la fabricabilité est excellente. La machine dynamoélectrique selon la présente invention comprend : un stator (2); un rotor (1) disposé sur le côté radialement intérieur du stator (2), le rotor (1) comportant un arbre rotatif (10); un palier (16) destiné à supporter l'arbre rotatif (10); une armature intermédiaire (15) destinée à supporter le stator (2); et une armature de stator (8) destinée à supporter le palier (16) et l'armature intermédiaire (15). L'armature de stator (8) comprend des socles (83) aux deux sections d'extrémité dans le sens de la largeur de sa partie inférieure. Les socles (83) comprennent chacun une surface supérieure (83a) positionnée plus haut que la surface inférieure de l'armature de stator (8). L'armature intermédiaire (15) est fixée aux surfaces supérieures (83a) des socles (83).
(JA) 本発明の目的は、フレームと軸受の振動を抑制することができ、製作性のよい回転電機を提供することである。本発明による回転電機は、固定子(2)と、固定子(2)の径方向内側に配置され、回転軸(10)を備える回転子(1)と、回転軸(10)を支持する軸受(16)と、固定子(2)を支持する中間フレーム(15)と、軸受(16)と中間フレーム(15)を支持する固定子フレーム(8)とを備える。固定子フレーム(8)は、底部の幅方向の両端部に台座(83)を備える。台座(83)は、固定子フレーム(8)の底面より上方に位置する上面(83a)を備える。中間フレーム(15)は、台座(83)の上面(83a)に固定される。
