Title (EN) ROTATING ELECTRIC MACHINE
(FR) MACHINE TOURNANTE ÉLECTRIQUE
(JA) 回転電機
Abstract:
(EN) The rotating electric machine according to the present invention has a rotor having: a rotor core; a permanent magnet buried in the rotor core; and a one-end side end plate for supporting one end side of the rotor core. The rotor core is provided with a rotor refrigerant path through which a refrigerant for cooling the permanent magnet circulates in the axial length direction of a shaft. The one-end side end plate is provided with an end plate refrigerant path communicating with the rotor refrigerant path. The end plate refrigerant path is provided with a refrigerant reservoir projecting outside in the radial direction of the shaft.
(FR) La présente invention concerne une machine tournante électrique comprenant un rotor comportant : un noyau de rotor ; un aimant permanent enfoui dans le noyau de rotor ; et une plaque d'extrémité de côté d'extrémité destinée à porter un côté d'extrémité du noyau de rotor. Le noyau de rotor est pourvu d'un circuit de fluide frigorigène de rotor dans lequel circule un fluide frigorigène destiné à refroidir l'aimant permanent dans le sens de la longueur axiale d'un arbre. La plaque d'extrémité de côté d'extrémité est pourvue d'un circuit de fluide frigorigène de plaque d'extrémité communiquant avec le circuit de fluide frigorigène de rotor. Le circuit de fluide frigorigène de plaque d'extrémité est pourvu d'un réservoir de fluide frigorigène faisant saillie vers l'extérieur dans la direction radiale de l'arbre.
(JA) この発明による回転電機では、ロータは、ロータコアと、ロータコアに埋め込まれる永久磁石と、ロータコアの一端側を支持する一端側端板とを有する。ロータコアには、永久磁石を冷却するための冷媒がシャフトの軸長方向に流通するロータ冷媒路が設けられる。一端側端板には、ロータ冷媒路と連通する端板冷媒路が設けられる。端板冷媒路には、シャフトの径方向外側に突出する冷媒溜りが設けられる。
