In accordance with at least one aspect of this disclosure, a system (100) includes an airflow line (108), a main compressor (110) disposed in the airflow line configured to receive a ram air flow (112) and supply a compressed air flow (113) to the air flow line, and a motor (114) operatively connected to drive the main compressor. An air cycle machine (116) is disposed in the airflow line downstream of the main compressor configured to receive the compressed airflow and supply a cooled cabin airflow (117) to an aircraft cabin (104). A cooling line tap (118) disposed in the airflow line downstream of the air cycle machine configured to communicate a flow of cooling air (119) to the motor from the airflow line to supply a portion of the cooled cabin airflow to one or more portions of the motor as motor cooling air (119) via a first cooling airflow line (120).
