  • Patent number: 6087746
    Abstract: A motor vehicle alternator has a casing carrying a stator, with a rotor of the interleaved-claw type mounted rotatably within it. Air inlet ports are provided in the casing of the machine, on one side, and air outlet ports on the opposite side, to allow cooling air to flow through the machine. The air inlet ports are situated closer to the axis of rotation of the rotor than the air outlet ports. In this way, rotation of the rotor produces a flow of air through the machine by centrifugal effect. The alternator may then be made without any ventilating fan.

  • Patent number: 5270605
    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.
