AIR BLOWER FOR A MOTOR-DRIVEN COMPRESSOR

摘要

A fluid compression system (10) includes a compressor, an electric motor (15) including a stator (30) and a rotor (20) positioned adjacent to the stator, and a shaft (40) 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 (205) are integrally-formed as part of the shaft and is adapted to induce a flow of fluid (210) from the non-drive end toward the drive end in response to rotation of the shaft.
