A motor includes a housing including separate motor and bearing cooling inlets. A motor is arranged within the housing and includes a stator and rotor assembly that is supported on air bearings. The motor cooling inlet is in fluid communication with the stator, and the bearing cooling inlet is in fluid communication with the air bearings. A vent is arranged in the housing and is common to the motor and bearing cooling inlets. The vent is in fluid communication with a low pressure side of a ram air duct. The bearing cooling duct is in fluid communication with a high pressure side of a ram air duct, such as through a reverse J-tube. A differential pressure between the high and low pressure sides moves cooling fluid from the bearing cooling inlet to the vent to cool the bearings.
