摘要： A control device for an alternator which can be fabricated as a single hybrid integrated circuit. The output of the alternator which is to be used to drive the field coil of the generator is rectified, and the rectified voltage is voltage divided by two resistors, one of which has a smoothing capacitor connected in parallel therewith. A detection and amplification transistor amplifies the signal at the junction point of the resistors and applies the amplified signal through a Zener diode to the base of a control transistor, the latter driving a switching transistor which controls the amount of current passing through the field coil of the generator.

摘要： A control apparatus for controlling the power supply to the field coil of a charging generator in which a smoothing capacitor of a low capacitance value is provided to prevent maloperation in the control circuit due to ripples in the output of the generator. A switching transistor controls the current flow through the field coil, while a control transistor controls the switching transistor and a zener diode is provided for energizing the control transistor. A first detection circuit is connected to the smoothing capacitor for detecting the rectified output of the generator and thereby producing a voltage at a first detection point. A second detection circuit produces a voltage at a second detection point which is higher than the first detection point voltage. An amplifying transistor having a base connected to the first detection point energizes the zener diode in accordance with the state of the output of either of the first and second detection circuits.

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.
