Abstract
A compressor includes a rotor driven by a shaft and configured to compress air, and a motor for driving the shaft. At least one bearing is utilized for facilitating rotation of the shaft. A motor cooling loop is configured to provide motor cooling air to the motor. A bearing cooling loop is configured to provide bearing cooling air to the at least one bearing. A bearing support is configured to support the least one bearing. The rotor includes an opening which is configured to communicate bearing cooling air into a cavity between the rotor and the bearing support. A method for cooling a compressor is also disclosed.
