Abstract
A system can include a compressor outlet line configured to receive compressor outlet flow from a compressor, a bypass line in fluid communication with the compressor outlet line and a motor outlet line to divert a bypass flow of the compressor outlet flow. The system can include at least one pump in fluid communication between the bypass line and the motor outlet line such that the bypass flow at least partially drives the pump to pull cooling flow through a motor to cool the motor.
