Rotor for rotary electric machine

回転電機用ロータ

Abstract

PROBLEM TO BE SOLVED: To provide a rotor for a rotary electric machine capable of easily narrowing or eliminating a gap between a laminate and an annular end plate. SOLUTION: An annular spacer 18 of the same size with an annular steel plate 22 is provided between a laminate of which a protruding part 34 for jointing is protruded on the end face and an upper end plate 30 on the protruding part 34 side of the upper end plates 30 pinching the laminate. The annular spacer 18 is provided with a through hole in which the protruding part 34 is housed. The upper end plate 30 on the protruding part 34 side is also provided with an annular groove 42 for housing the protruding part 34. COPYRIGHT: (C)2005,JPO&NCIPI
【課題】より容易に積層体と環状端板との間の隙間を小さく、または、無くすことができる回転電機用ロータを提供する。 【解決手段】端面に接合用凸部である突起部34が突出している積層体と、積層体を挟持する上端プレート30のうち突起部34側の上端プレート30との間に、環状鋼板22と同じ大きさの環状スペーサ18を設ける。環状スペーサ18は、突起部34が収納できる貫通孔が形成されている。また、突起部34側の上端プレート30にも、突起部34収納のための環状溝42が形成されている。 【選択図】 図6
