A system for generating air includes: an electromechanical device generating an airflow equipped with an air inlet opening and an outlet; a casing extending between a first end attached to the air inlet opening and a second end located opposite the first end, the casing including two parts together defining a closed recess, each part including a hollow wall defining a channel extending between the two ends of the casing, each channel opening in front of the air inlet opening so that the electromechanical device is supplied with air routed by the channels; and at least one electronic card for power supply or control of the electromechanical device located in the recess of the casing.

Air generation system comprising an electromechanical device, a casing and an electronic card

The invention relates to an electric centrifugal compressor, in particular for a turbine engine or aircraft, including an electric motor, the stator of which is supported by a casing and the rotor of which includes a shaft mounted inside the casing, driving a centrifugal compressor impeller, the casing having a double skin and including two substantially cylindrical, coaxial skins extending around the engine and defining between them an annular section suitable for the circulation of a first cooling air flow, one inlet of which is located at a first longitudinal end of the shaft and an outlet of which is connected to a second longitudinal end of the shaft, which supports the centrifugal compressor impeller, wherein it includes means (J) for collecting a second air flow at the outlet of the centrifugal compressor impeller, means for channelling the second air flow along the shaft up to the first end, and means for discharging the second air flow out of the casing in order to prevent same from mixing with the first air flow.
