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 facilitates 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 bearing support includes an opening. A duct is configured to communicate air from the opening to an inlet of the compressor. A method for cooling a compressor is also disclosed.
