  • Alternator with improved cooling means, especially for motor vehicles
    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.
