Patentansprüche:Patent claims: 1. Belüftungseinrichtung für die Wicklungsköpfe von Induktionsmotoren, deren Läuferwicklung mit Lüfterfahnen ausgerüstet sind, und bei welchen beiderseits der Maschine je ein Zusatzlüfter vorgesehen ist, dadurch gekennzeichnet, daß die einen größeren Außendurchmesser als der Läufer besitzenden Zusatzlüfter (d) mit den Lüfterfahnen (f) der Läuferwicklung in Reihe geschaltet und so angeordnet sind, daß sie die von den Läuferlüfterfahnen angesaugte Luft in zwei die Spulenköpfe des Ständers allseitig umspülende Luftströme (k und p) zerlegen.1. Ventilation device for the winding heads of induction motors, the rotor windings of which are equipped with fan vanes, and in which an additional fan is provided on each side of the machine, characterized in that the additional fan (d) with the fan vanes (f) has a larger outer diameter than the rotor. the rotor winding are connected in series and arranged in such a way that they split the air sucked in by the rotor fan vanes into two air currents (k and p) which wash around the coil heads of the stator on all sides. 2. Belüftungseinrichtung nach Anspruch 1, dadurch gekennzeichnet, daß sich der eine Teilluftstrom (p) unter dem Einfluß der Läuferfahnen zwischen den Spulenköpfen und dem Ständereisen (c) hindurchbewegt.2. Ventilation device according to claim 1, characterized in that the one partial air flow (p) moves through under the influence of the rotor vanes between the coil heads and the stator iron (c). 3. Belüftungseinrichtung nach den An-Sprüchen 1 und 2, dadurch gekennzeichnet, daß die Zusatzlüfter (d) mit Abdeckungen (g) versehen sind, vermittels deren sie am Läufer (δ) befestigt sind.3. Ventilation device according to claims 1 and 2, characterized in that the additional fan (d) are provided with covers (g) , by means of which they are attached to the runner (δ). 4. Belüftungseinrichtung nach den An-Sprüchen 1 bis 3, dadurch gekennzeichnet, daß beide Zusatzlüfter (d) auf der Welle (ff) der Maschine angeordnet sind.4. Ventilation device according to claims 1 to 3, characterized in that both additional fans (d) are arranged on the shaft (ff) of the machine.
