Title (EN) ROTARY ELECTRIC ROTOR AND METHOD FOR MANUFACTURING ROTARY ELECTRIC ROTOR
(FR) ROTOR ÉLECTRIQUE ROTATIF ET PROCÉDÉ DE FABRICATION DE ROTOR ÉLECTRIQUE ROTATIF
(JA) 回転電機のロータ、及び回転電機のロータの製造方法
Abstract:
(EN) This rotor (20) is configured by stacking a plurality of steel plates (21) and burying the plurality of magnets (22, 23, 24) into respective slots (61, 62, 63). The steel plates (21) have holes (41, 42) and bridge parts (Br5) that are inserted into the two holes (41, 42), wherein the bridge parts (Br5) are disposed spaced apart in a plurality of places in a suspension direction, and have a plurality of magnetic resistance parts (51, 52) having smaller magnetic permeabilities than other portions of the steel plates (21). Accordingly, leakage magnetic flux in the bridge parts (Br5) can be efficiently reduced.
(FR) L'invention concerne un rotor (20) qui est conçu par empilement d'une pluralité de plaques d'acier (21) et par enfouissement de la pluralité d'aimants (22, 23, 24) dans des fentes respectives (61, 62, 63). Les plaques d'acier (21) présentent des trous (41, 42) et des parties de pont (Br5) qui sont insérées dans les deux trous (41, 42), les parties de pont (Br5) étant disposées espacées dans une pluralité d'emplacements dans une direction de suspension, et possédant une pluralité de parties de résistance magnétique (51, 52) ayant des perméabilités magnétiques plus petites que d'autres parties des plaques d'acier (21). En conséquence, le flux magnétique de fuite dans les parties de pont (Br5) peut être efficacement réduit.
(JA) ロータ(20)は、複数の鋼板(21)が積層され、かつ複数の磁石(22,23,24)がそれぞれのスロット(61,62,63)に埋設されて構成されている。鋼板(21)は、孔(41,42)と、二つの孔(41、42)に挟まれるブリッジ部(Br5)とを有しており、ブリッジ部(Br5)は、懸架方向の複数箇所に間隔を空けて配置され、鋼板(21)の他の部位よりも透磁率が低減された複数の磁気抵抗部(51,52)を有している。これにより、ブリッジ部(Br5)における漏れ磁束を効率的に低減することができる。
