Abstract
An alternating-current generator, in particular a three-phase generator, for a motor vehicle, having a rotor including north and south poles, particularly having claw-pole fingers extending in the axial direction and alternating as north and south poles at the rotor's periphery, a stator having a magnetic core, especially laminated core, having slots and a stator winding disposed in the magnetic core's slots, the stator winding having winding overhangs that are coolable by an approximately radial air flow produced by at least one fan mounted at the rotor, the stator being situated opposite the rotor, and the stator and the rotor having defined positions relative to each other, the multiphase stator winding being made up of winding elements, at least one winding element having more than two sections inserted in slots, and at least one winding element having more than one reversal section which brings about a change in the radial position.
