Abstract
A compressor includes a rotor configured to compress air and driven by a shaft. A motor is drives the shaft. The first and second journal bearings facilitate rotation of the shaft. The first journal bearing is upstream from the motor and the second journal bearing is downstream from the motor. The transfer tube is configured to provide cooling air from a bearing cooling air inlet to the first journal bearing. A method for cooling a compressor is also disclosed.
