Abstract

An nitrogen generation system for an aircraft is provided. The system includes a RAM air circuit, a motor driven compressor (MDC) having a rotor, a stator to drive rotor rotation and a compressor rotatably coupled to the rotor and a cooling system. The cooling system directs cooling air from the RAM air circuit to an inlet of the compressor and an alternative low pressure environment such that the cooling air removes heat from the stator.
