The ac generator has the front region (48) of the outer surface (43) of each of its claw-shaped poles (28,29) passing over into the rearward edge (52) by means of more than one surface (50,51) running across the direction of rotation (D). The flat surface near the rear wall has a larger angle of inclination to a tangent (53) lying on the outer surface (43) in the region of the narrowest air gap (37) of the pole (28,29) concerned than the flat plane lying in front in the direction of the front region.
