Abstract
A three-phase alternator for a motor vehicle has a rotor consisting of two pole wheels, each comprising a radial plate and a plurality of projecting teeth. Each tooth has an outer surface and two lateral surfaces, the outer surface being joined to a rear face of the radial plate through an inclined surface. Each tooth is formed with at least one antinoise chamfer adjacent to the outer surface, lateral surface, and inclined surface of the tooth, and adjacent also to the rear face, the antinoise chamfer being inclined by a different angle from that of each of these surfaces to which it is adjacent.
