Abstract: In one aspect, a flexible fan blade for use in a centrifugal fan impeller having at least one of a rear plate and a front plate with an air inlet is provided. The flexible fan blade comprises a fixed central portion fixedly coupled to at least one of the front plate and the rear plate of the centrifugal fan impeller. The flexible fan blade also includes a trailing edge extending from the fixed central portion and being moveable between a first position and a second position. The trailing edge is fabricated from a compliant material. Furthermore, the trailing edge is flexible in relation to the fixed central portion between a first position and a second position. The flexible fan blade also includes a leading edge extending from the fixed central portion in opposed relation to the trailing edge.

Abstract: A fluid circulating assembly includes a fan impeller having an inlet ring and a rear plate that define a central chamber. The fluid circulating assembly includes an electrical machine having a rotor assembly, a stator assembly, and a housing. The electrical machine is coupled to the rear plate of the impeller such that the electrical machine is positioned entirely outside the central chamber. The housing includes a plurality of fins on a side of the housing opposite the rear plate. The fins extend axially away from the stator assembly. The assembly includes a duct attached to the housing. The duct covers a portion of the fins and extends radially outward from the housing towards an outer edge of the rear plate. The duct is configured to channel air over the portion of the fins to facilitate cooling the electrical machine.
