Schaltung für elektrisch angetriebene Ventilatoren, die zur Kühlung von Hauptstrommotoren dienen.Circuit for electrically driven fans that are used for cooling are used by main current motors.

Patentiert im Deutschen Reiche vom 24. Juni 1905 ab.Patented in the German Empire on June 24, 1905.

Werden elektrisch angetriebene VentilatorenAre electrically powered fans

zur Kühlung von Hauptstromelektromotorenfor cooling main current electric motors

. benutzt, so werden sie gemäß vorliegender Erfindung der Feldwicklung des zu kühlenden. used, they are according to the present invention of the field winding to be cooled

5. Motors parallel geschaltet.5. Motor connected in parallel.

Diese Anordnung bietet den Vorteil, daßThis arrangement has the advantage that

die Drehzahl und damit die Leistung . des Ventilators sich selbsttätig mit der Belastung des zu kühlenden Motors ändert und daß derthe speed and thus the power. of the fan automatically with the load of the motor to be cooled and that the

ίο Ventilatormotor nur mit geringer Spannung arbeitet. Letzteres ist besonders wichtig bei Verwendung hoher Betriebsspannungen.ίο Fan motor only with low voltage is working. The latter is particularly important when using high operating voltages.
