Abstract: front page image
(EN)This invention reduces the size of a dynamo-electric machine provided with a cooling mechanism. Said dynamo-electric machine has a stator and either an inner rotor laid out radially inwards of the stator or an outer rotor laid out radially outwards of the stator. The stator has a stator core, a cooling tube that cools the stator, and a stator coil wound around the stator core and the cooling tube. In the direction of the axis of rotation of the stator, the cooling tube is laid out on the side surface of the stator core, and the section of the cooling tube that corresponds to the stator core comprises a magnetic material.
(FR)L'invention permet de réduire la taille d'une machine dynamo-électrique équipée d'un mécanisme de refroidissement. Ladite machine dynamo-électrique comporte un stator, et soit un rotor intérieur installé radialement à l'intérieur du stator, soit un rotor extérieur installé à l'extérieur du stator. Le stator comporte un noyau de stator, un tube de refroidissement qui refroidit le stator, et un enroulement de stator, enroulé autour du noyau de stator et du tube de refroidissement. Dans la direction de l'axe de rotation du stator, le tube de refroidissement est installé sur la surface latérale du noyau de stator, et la section du tube de refroidissement qui correspond au noyau de stator comprend un matériau magnétique.
(JA) 冷却機構を備えた回転電機の体格を抑制する。ステータと、ステータの径方向内側に配置されたインナーロータまたはステータの径方向外側に配置されたアウターロータと、を有し、ステータは、ステータコアと、ステータを冷却する冷却管と、ステータコアおよび冷却管を巻回するステータコイルと、を有し、ステータの回転軸方向において、ステータコアの側面に冷却管が配置され、冷却管のステータコアに対応する部分が磁性材料で構成される回転電機。
