MOTOR HOUSING ASSEMBLY FOR A CABIN AIR COMPRESSOR

摘要

A motor housing assembly for a cabin air compressor assembly is provided that includes a central body portion, a first end portion, and a second end portion. The central body portion has an internal cavity configured to receive an electric motor. The first end portion includes a first and second motor cooling inlet duct. The second end portion includes a flange configured to couple with an outlet housing of the cabin air compressor assembly. A motor cooling duct centerline is defined between the first and second motor cooling inlet duct and is perpendicular to a central body portion centerline. A first distance is defined between an outer edge of the first and second motor cooling inlet duct. A second distance is defined between an outer face of the flange and an intersection of the centerlines. A ratio of the first distance to the second distance is between 1.29 and 1.3.
