ABSTRACT:
An automotive generator that includes a Lundell rotor. First and second protruding portions are disposed so as to project from inner wall surfaces of portions of first and second yoke portions at root portions of first and second claw-shaped magnetic pole portions, and first and second recess portions are recessed into inner wall surfaces of portions of the first and second yoke portions that face the second and first protruding portions. In addition, a shape of a region in which the field coil is disposed is configured into a wave shape that has a cross-sectional shape in a plane that includes a central axis of the pole core that is approximately constant in a circumferential direction and that zigzags alternately in an axial direction at positions of each of the first and second claw-shaped magnetic pole portions.
