    • A vehicular alternating current generator includes a Lundell rotor and a stator. The Lundell rotor includes a cylindrical portion around which a field coil is wound; plate-shaped first and second end plate portions disposed on both end faces in an axial direction of the cylindrical portion so as to face each other; a plurality of first claw portions extending in parallel with a rotational axis in a direction from the first end plate portion to the second end plate portion; and second claw portions extending in parallel with the rotational axis in a direction from the second end plate portion to the first end plate portion, the second claw portions being disposed circumferentially and alternately relative to the first claw portions. The stator is disposed on an outer periphery of the rotor so as to face the rotor with a small rotational air gap there between.
    • 车辆交流发电机包括隆德尔转子和定子。 隆德尔转子包括圆柱形部分,围绕其缠绕励磁线圈; 平板状的第一和第二端板部分设置在圆柱形部分的轴向方向上的两个端面上以彼此面对; 多个第一爪部,其在从所述第一端板部到所述第二端板部的方向上与旋转轴线平行地延伸; 以及第二爪部,其在从所述第二端板部到所述第一端板部的方向上与所述旋转轴平行地延伸,所述第二爪部相对于所述第一爪部沿周向和交替地设置。 定子设置在转子的外周上,以便在转子之间具有小的旋转气隙。
