摘要： An alternating current generator with a pulley (17) for transmitting driving force from an engine to a rotor and/or to an auxiliary machine, having an external axial fan (18), rotating unitedly with the pulley (17), for drawing external air into the inside of the AC generator through air intake holes provided on both covers of the AC generator housing. The pulley (17) has air-intake vents (17a) axially extending through the pulley to permit relatively cold air to pass therethrough. At each such vent (17a), a guide member (17b) between the blades of the external axial fan (18) and the air intake holes directs the relatively cold air drawn in by the axial fan, to cool the interior components of the AC generator. The guide members (17b) further serve to shut out the outside air that has been heated from having passed near the outer surface of the housing.

摘要： An output power control device for an automotive AC generator includes a field current limiter circuit 9 for controlling the duty factor of the power transistor 305 coupled in series with the field coil 102A of the AC generator 1A, which is supplied with a maximum field current twice the conventional level. A frequency-to-voltage converter 903 converts the input frequency to a voltage corresponding to the rpm of the AC generator 1A, and a comparator 909 compares the sawtooth waveform generated by a sawtooth waveform generator 908 with the output of the frequency-to-voltage converter 903, the upper level of which is limited under a predetermined level by resistors 904 through 906 and a diode 907. When the rpm of the AC generator 1A exceeds a predetermined frequency, the pulse train generated by the comparator 909 reduces the duty factor of the power transistor 305, thereby controlling the level of the output current generated by the AC generator 1A.
