Abstract
To provide for effective cooling of an automotive-type alternator and/or other equipment within an automobile, for example the radiator or other heat exchanger, even under external high-temperature conditions and low engine speed (n.sub.E), for example under idling conditions, the alternator phase windings (6, 7, 8) are connected to respective phase windings (16, 17, 18) of a three-phase squirrel-cage motor which is connected to a blower (2), preferably a radial-type fan, directing forced air circulation towards the alternator and/or the vehicle radiator, the alternator then being placed within the airstream of the radiator as well. A temperature and/or speed-responsive switch can be interposed between the alternator and the motor to energize the motor only if the temperature of the alternator and/or the engine, or other component, rises above a predetermined level, or if the alternator speed drops below a predetermined level.
