ABSTRACT:
An alternator includes a housing having first and second axial end portions with a plurality of air intake ports for permitting air to pass through the axial end portions. The housing also includes first and second air exhaust ports which are spaced from one another. A stator assembly includes a stator core provided on an inner surface of the housing between the air exhaust ports and a stator winding wound around the stator core. A rotor assembly includes a rotor shaft, a rotor core fixed to the rotor shaft, and a rotor coil wound around the rotor core. The rotor shaft is rotatably supported by the axial end portions of the housing. A diode fin and a voltage regulator are disposed around an end of the rotor shaft. A pair of fans are mounted to the end surfaces of the pole cores of the rotor to increase the cooling efficiency of the alternator.
