| Zusammenfassung: | To provide a rotor for a rotary electric machine, a rotary electric machine, and an electric vehicle equipped with the rotary electric machine to suppress deformation of a rotor core and improve holding force of the rotor core fixed to a shaft.SOLUTION: A stator of a rotary electric machine of the present invention includes a shaft 260 and a rotor core 252 arranged radically outside of the shaft 260. The shaft 260 includes a shaft body 262, and a cylindrical body 264 located on the radially outer side of the shaft body 262 and facing the rotor core 252. The cylindrical body 264 includes a notch portion 264d extending in an axial direction, and welding is performed with a part of the rotor core 252 positioned in the notch portion 264d.SELECTED DRAWING: Figure 10
【課題】回転子コアの変形を抑制すると共に、シャフトに固定する回転子コアの保持力を向上させる。【解決手段】本発明の回転電機の固定子は、シャフト２６０と、シャフト２６０の径方向外側に配置された回転子コア２５２とを備える。シャフト２６０は、シャフト本体２６２と、シャフト本体２６２の径方向外側に位置し、回転子コア２５２と対向する筒状体２６４とを備える。筒状体２６４には、軸方向に伸びた切欠き部２６４ｄを備え、切欠き部２６４ｄに回転子コア２５２の一部を位置させた状態で溶接を施した。【選択図】 図１０ |
