Abstract
A motor housing for a cabin air compressor includes a central body portion having a center wall thickness and an internal cavity that is configured to receive an electric motor, a first end portion having a second internal cavity that is configured to receive a first end winding of the stator, and a second end portion having a third internal cavity configured to receive a second end winding of the stator. A ratio of a wall thickness of either of the first or the second end portions to the motor wall thickness is at least greater than 1.68 to 1.
