Title
(EN) ROTATING ELECTRIC MACHINE AND MANUFACTURING METHOD OF ROTATING ELECTRIC MACHINE
(FR) MACHINE ÉLECTRIQUE ROTATIVE ET PROCÉDÉ DE FABRICATION D'UNE MACHINE ÉLECTRIQUE ROTATIVE
(JA) 回転電機、および回転電機の製造方法
Abstract
(EN) A rotating electric machine, according to the present invention, is provided with: a stator which has a plurality of segment conductors and an iron core formed with a plurality of slots, the plurality of segment conductors being disposed in the plurality of slots, and a rotor disposed on the inner peripheral side of the stator, wherein the segment conductors have a straight part that is disposed inside the slots, an inclined part curved at a prescribed angle with respect to the straight part, and a curved part between the straight part and the inclined part, and the curved part has recessed sections on the inner side and outer side thereof or on both side surfaces thereof.
(FR) La présente invention concerne une machine électrique rotative dotée : d'un stator qui a une pluralité de conducteurs de segment et un noyau de fer constitué d'une pluralité de fentes, la pluralité de conducteurs de segment étant disposés dans la pluralité de fentes, et d'un rotor disposé sur le côté périphérique interne du stator, les conducteurs de segment ayant une partie droite qui est disposée à l'intérieur des fentes, une partie inclinée incurvée selon un angle prescrit par rapport à la partie droite, et une partie incurvée entre la partie droite et la partie inclinée, et la partie incurvée a des sections évidées sur le côté interne et sur le côté externe ou sur les deux surfaces latérales.
(JA) 複数のセグメント導体と、複数のスロットが形成された鉄心とを有し、前記複数のセグメント導体を前記複数のスロットに配置した固定子と、前記固定子の内周側に配置される回転子とを備えた回転電機において、前記セグメント導体は、前記スロット内に配置される直線部と、前記直線部に対して所定の角度に折り曲げられた傾斜部と、前記直線部と前記傾斜部との間の折り曲げ部とを有し、前記折り曲げ部は、前記折り曲げ部の内側と外側に、または前記折り曲げ部の両側面に凹状部を有している回転電機。
