Abstract:
(EN) A rotating electrical machine 20 comprising a stator 22 and a rotor 24. The stator 22 has a stator core 40 and an armature winding 42 wound around the stator core 40. The rotor 24 is arranged facing the stator 22 in the radial direction, on the inside of the stator 22 in the radial direction. The rotor 24 has: a field core 50 having a plurality of magnetic pole sections 62 each forming a plurality of magnetic poles having alternating polarity in the circumferential direction; a field winding 52 wound around the field core 50; and a cylindrical short circuit member 54 arranged on the outside, in the radial direction, of the magnetic pole sections 62 so as to cover the outer surface of the magnetic pole sections 62 in the radial direction and magnetically connecting magnetic pole sections 62 adjacent in the circumferential direction. Both end sections 54t of the short circuit member 54, in the axial direction, protrude further outside in the axial direction than both end sections, in the axial direction, of the stator core 40.
(FR) L'invention concerne une machine électrique tournante 20 comprend un stator 22 et un rotor 24. Le stator 22 a un noyau de stator 40 et un enroulement d'enduit 42 enroulé autour du noyau de stator 40. Le rotor 24 est disposé en vis-à-vis du stator 22 dans la direction radiale, à l'intérieur du stator 22 dans la direction radiale. Le rotor 24 comprend : un noyau de champ 50 ayant une pluralité de sections de pôle magnétique 62, formant chacune une pluralité de pôles magnétiques ayant une polarité alternée dans la direction circonférentielle ; un enroulement de champ 52 enroulé autour du noyau de champ 50 ; et un élément de court-circuit cylindrique 54 disposé sur l'extérieur, dans la direction radiale, des sections de pôle magnétique 62 de manière à recouvrir la surface externe des sections de pôle magnétique 62 dans la direction radiale et à connecter magnétiquement les sections de pôle magnétique 62 adjacentes dans la direction circonférentielle. Les deux sections d'extrémité 54t de l'élément de court-circuit 54, dans la direction axiale, font davantage saillie vers l'extérieur dans la direction axiale que les deux sections d'extrémité, dans la direction axiale, du noyau de stator 40.
(JA) 回転電機20は、ステータ22とロータ24とを備えている。ステータ22は、ステータコア40と、ステータコア40に巻装されている電機子巻線42とを有する。ロータ24は、ステータ22の径方向内側においてステータ22と径方向に対向して配置されている。ロータ24は、極性が周方向において交互に異なる複数の磁極をそれぞれ形成する複数の磁極部62を有する界磁コア50と、界磁コア50に巻装されている界磁巻線52と、磁極部62の径方向外側において磁極部62の径方向外面を覆うように配置されて、周方向に隣り合う磁極部62同士を磁気的に接続する筒状の短絡部材54とを有する。そして、短絡部材54の軸方向両端部54tが、それぞれステータコア40の軸方向両端より軸方向外側にはみ出している。
