Abstract: According to some embodiments of the present disclosure, an aircraft electric motor is disclosed. The motor includes a rotor comprising a plurality of magnet segments arranged on a frame of the rotor. The motor also includes an output shaft operably coupled to the rotor radially inward from the plurality of magnet segments and a stator. The stator includes a radially outer rim and at least one winding wrapped about a plurality of stator teeth. The stator is arranged around the rotor and includes cooling fins extending radially outward from the radially outer rim. The cooling fins include wide fins that have a width ww distributed about the radially outer rim and thin fins that have width wt. The thin fins are disposed between the wide fins. The width of the wide fins ww is greater than the width wt of the thin fins.

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.
