Abstract:
(EN) Provided is a dynamo-electric machine in which vibration occurring during driving can be suppressed and which can be made compact. This dynamo-electric machine is provided with: a rotor 1; a stator 2 having a stator core 21 provided outside the rotor in the radial direction of the rotor 1; a motor frame 3 which has a cylinder section 31 provided outside the stator core 21 in the radial direction and to which the stator 2 is affixed; and an intermediate member 4 provided to the outer peripheral surface, in the radial direction, of the stator core 21 while being press fitted in the inner peripheral surface, in the radial direction, of the cylinder section 31. The rigidity per unit length of the intermediate member 4 is higher than the rigidity per unit length of the cylinder section 31.
(FR) L'invention concerne une machine dynamoélectrique dont les vibrations se produisant pendant l'entraînement peuvent être supprimées et qui peut être rendue compacte. Cette machine dynamoélectrique est pourvue : d'un rotor 1 ; d'un stator 2 ayant un noyau de stator 21 disposé à l'extérieur du rotor dans la direction radiale du rotor 1 ; d'un bâti de moteur 3 qui a une section de cylindre 31 disposée à l'extérieur du noyau de stator 21 dans la direction radiale et auquel est fixé le stator 2 ; et d'un élément intermédiaire 4 disposé sur la surface périphérique externe, dans la direction radiale, du noyau de stator 21 tout en étant ajusté par pression dans la surface périphérique interne, dans la direction radiale, de la section de cylindre 31. La rigidité linéique de l'élément intermédiaire 4 est supérieure à la rigidité linéique de la section de cylindre 31.
(JA) 駆動時に発生する振動を抑制することができるとともに、小型化を図ることができる回転電機を得る。この回転電機は、回転子1と、回転子1の径方向について回転子よりも外側に設けられた固定子コア21を有する固定子2と、径方向について固定子コア21よりも外側に設けられた筒部31を有し、固定子2が固定されたモータフレーム3と、径方向についての固定子コア21の外周面に設けられ、径方向についての筒部31の内周面に圧入された状態の中間部材4とを備え、中間部材4の単位長さ当たりの剛性は、筒部31の単位長さ当たりの剛性よりも高い。
