Title (EN) ROTATING ELECTRIC MACHINE
(FR) MACHINE TOURNANTE ÉLECTRIQUE
(JA) 回転電機
Abstract:
(EN) A rotor of a rotating electric machine has a rotor shaft and a rotor body provided on the rotor shaft. A baffle plate is fixed to an end of the rotor body in the shaft direction at a plurality of positions and forms a ventilation path for a cooling gas. The baffle plate is also divided into a plurality of baffle divided bodies arranged in the circumferential direction of the rotor. Each of the baffle divided bodies has an overlap portion overlapped with an adjacent baffle divided body in the shaft direction of the rotor.
(FR) Un rotor d'une machine tournante électrique comporte un arbre de rotor et un corps de rotor disposé sur l'arbre de rotor. Une plaque déflectrice est fixée à une extrémité du corps de rotor dans la direction de l'arbre à une pluralité de positions et forme un trajet de ventilation pour un gaz de refroidissement. La plaque déflectrice est également divisée en une pluralité de corps divisés déflecteurs agencés dans la direction circonférentielle du rotor. Chacun des corps divisés déflecteurs a une partie de chevauchement chevauchée par un corps divisé déflecteur adjacent dans la direction de l'arbre du rotor.
(JA) 回転電機において、回転子は、回転子軸と、回転子軸に設けられている回転子本体とを有している。バッフルプレートは、回転子本体の軸方向の端部に複数箇所で固定されており、冷却ガスの通風路を形成する。また、バッフルプレートは、回転子の周方向に並んだ複数のバッフル分割体に分割されている。各バッフル分割体は、隣接するバッフル分割体と回転子の軸方向に重なる重なり部を有している。
