A power electronics cooling system (100) includes a ram air fan (102) with one or more blades (252) and a ram air fan motor (130) connected via an output shaft (120). The ram air fan (102) draws in air and passes it across a heat exchanger (112) to cool one or more cooling liquids (108,118). One or more pumps (104,114) pressurize and pump the cooling liquids (108,118) to various electronic components, including one or more motor controllers (136,178). The pumps (104,114) may be mechanically or electrically coupled to the output shaft (120) of the ram air fan (102), such that the motor of the ram air fan (130) provides energy to the pumps.
