Title (EN) ELECTRIC COMPRESSOR
(FR) COMPRESSEUR ÉLECTRIQUE
(JA) 電動コンプレッサ
Abstract:
(EN) This electric compressor comprises a rotating shaft, a compressor impeller, a rotor part, a stator part, and a motor housing. The motor housing is provided with an inner housing including a first cylindrical part that encircles and holds the stator part, and an outer housing including a second cylindrical part that encircles and holds the first cylindrical part of the inner housing. The outer peripheral surface of the stator part is in contact with the inner peripheral surface of the first cylindrical part of the inner housing. A first groove part disposed so as to revolve one or more times around the axis of the rotating shaft is formed in the outer peripheral surface of the first cylindrical part, and the first groove part includes a linear groove part.
(FR) L'invention porte sur un compresseur électrique comprenant un arbre rotatif, une roue de compresseur, une partie rotor, une partie stator et un carter de moteur. Le carter de moteur comporte un carter intérieur qui comprend une première partie cylindrique qui entoure et maintient la partie stator; et un carter extérieur qui comprend une seconde partie cylindrique qui entoure et maintient la première partie cylindrique du carter intérieur. La surface périphérique externe de la partie stator est en contact avec la surface périphérique interne de la première partie cylindrique du carter intérieur. Une première partie de rainure disposée de manière à tourner une ou plusieurs fois autour de l'axe de l'arbre rotatif est formée dans la surface périphérique externe de la première partie cylindrique, et la première partie de rainure comprend une partie de rainure linéaire.
(JA) 電動コンプレッサは、回転軸と、コンプレッサインペラと、ロータ部と、ステータ部と、モータハウジングと、を備える。モータハウジングは、ステータ部を包囲して保持する第1筒状部を含むインナーハウジングと、インナーハウジングの第1筒状部を包囲して保持する第2筒状部を含むアウターハウジングと、を備える。ステータ部の外周面は、インナーハウジングの第1筒状部の内周面に当接している。第1筒状部の外周面には、回転軸の軸線回りに1周以上旋回するように配置された第1溝部が形成され、第1溝部は、せん状の溝部を含んでいる。
