(FR) MOTEUR
(JA) モータ
Abstract:
(EN) On embodiment of the motor according to the present invention is provided with a shaft having a central axis extending in a predetermined direction as the center thereof and a stator positioned outside the shaft in the radial direction. The stator has a coil wound therearound. The motor is further provided with: a bottomed substantially cylindrical housing member for housing the substantial whole of the stator and supporting the shaft; a cooling medium which is filled inside the housing member and in which the stator and the coil are immersed; and a rotor rotating outside the housing member in the radial direction about the central axis of the shaft.
(FR) Un mode de réalisation de la présente invention concerne un moteur, qui comporte un arbre ayant un axe central s'étendant dans une direction prédéterminée constituant le centre de celui-ci et un stator positionné à l'extérieur de l'arbre dans la direction radiale. Le stator a un enroulement enroulé autour de celui-ci. Le moteur comporte de plus : un élément de boîtier sensiblement cylindrique avec un fond pour renfermer sensiblement l'ensemble du stator et supporter l'arbre ; un milieu de refroidissement qui remplit l'intérieur de l'élément de boîtier et dans lequel le stator et l'enroulement sont immergés ; et un rotor tournant à l'extérieur de l'élément de boîtier dans la direction radiale autour de l'axe central de l'arbre.
(JA) 本発明のモータの一つの態様は、所定方向に延びる中心軸を中心とするシャフトと、前記シャフトの径方向外側に位置するステータと、を備え、前記ステータは、当該ステータに巻回されるコイルを有し、前記モータはさらに、前記ステータの略全体を収容し、前記シャフトを支持する有底略円筒状のハウジング部材と、前記ハウジング部材内部に充填され、前記ステータ及び前記コイルを液浸する冷却媒体と、前記シャフトの中心軸を回転中心として、前記ハウジング部材の径方向外側で回転するロータと、を備える。
