Patent ID: 8878413

Claim:
An alternating-current generator, which is a multi-phase generator, for a motor vehicle, comprising: a rotor including north and south poles, having claw-pole fingers extending in the axial direction and alternating as north and south poles at the periphery of the rotor; and a stator having a magnetic core, the magnetic core being a laminated core, having slots and a multiphase stator winding disposed in the slots of the magnetic core, the stator winding having winding overhangs that in each case are able to be cooled 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 at least more than two sections inserted in the slots, and at least one winding element having more than one reversal section which brings about a change in a radial position; wherein the sections in the slots are arranged in each slot in one radial row, wherein the winding element has a number of loops, wherein the change in a radial position at a first reversal section is greater than in a second reversal section and the change in a radial position at a third reversal section is greater than in the second reversal section, and wherein the first reversal is followed by the second reversal in the direction of the wire path, and wherein the second reversal is followed by the third reversal in the same direction of the wire path.
