Abstract

Eine geräuscharme luftbewegende Motoranordnung umfasst eine Motoranordnung mit einer rotierbaren Welle, eine mit der rotierbaren Welle verbundene Lüfteranordnung, die einen Luftstrom erzeugt, der über wenigstens einen Teil der Motoranordnung strömt. Eine flammenselbstlöschende und geräuschunterdrückende Hülle ist wenigstens teilweise um die Motoranordnung angeordnet. Idealerweise ist die Hülle ein mit V-O bewertetes Schaummaterial. Die Lüfteranordnung umfasst einen Lüfter, der an der Welle befestigt ist und eine mit der Motoranordnung verbundene Diffusor/Träger-Anordnung, die rotierend die Welle empfängt. Eine Lüfterhaube ist an der Diffusor/Träger-Anordnung befestigt, wobei eine Rotation des Lüfters Luft durch die Lüfterhaube aus der Diffusor/Träger-Anordnung einsaugt, wobei die Diffusor/Träger-Anordnung wenigstens ein Schaumstück hat, das mit gekrümmten Flügeln verbunden ist, um die Geräusche hindurchströmender Luft zu reduzieren.A low noise air moving engine assembly includes a motor assembly having a rotatable shaft, a fan assembly coupled to the rotatable shaft that generates an airflow that flows over at least a portion of the engine assembly. A flame self-extinguishing and noise suppressing sleeve is at least partially disposed about the motor assembly. Ideally, the shell is a V-O rated foam material. The fan assembly includes a fan attached to the shaft and a diffuser / carrier assembly connected to the motor assembly that rotatively receives the shaft. A fan cowl is attached to the diffuser / carrier assembly with rotation of the fan drawing air through the fan cowl from the diffuser / carrier assembly, the diffuser / carrier assembly having at least one foam piece connected to curved wings to reduce the noise of air flowing through.
