Abstract
A fluid compression system includes a compressor, an electric motor including a stator and a rotor positioned adjacent to the stator, and a shaft coupled to the rotor to support the rotor for rotation and having a drive end and a non-drive end. A plurality of flow-inducing elements are integrally-formed as part of the shaft and is adapted to induce a flow of fluid from the non-drive end toward the drive end in response to rotation of the shaft.
