Abstract
A method for increasing stator cooling airflow in an air cooled electric motor is provided, wherein the air cooled electric motor includes a compressor outlet housing having a motor cavity separator wall and a separator plate defining a separator plate opening, wherein the compressor outlet housing defines a separator plate cavity and a compressor rotor back-face cavity configured to receive a back-face cavity airflow. The motor cavity separator wall separates the separator plate cavity from the compressor rotor back-face cavity and defines a motor cavity separator wall through-hole which communicates the separator plate cavity with the compressor rotor back-face cavity and a motor cooling housing including a motor cooling outlet structure which defines a stator outlet cavity, wherein the separator plate is disposed to separate the stator outlet cavity from the separator plate cavity.
