Abstract

A motor housing includes a motor support portion defining a central axis and including a first end and a second end, a wall surrounding the motor support portion, a surface offset from the wall toward the second end in a direction parallel with the central axis, a cooling air passageway oriented generally parallel with the central axis and offset from the central axis, and an inlet, opening directly into the cooling air passageway, at least partially defined between the wall and the surface. The inlet is configured to permit entry of a tangential airflow into the cooling air passageway, and the inlet is configured to permit entry of a radial airflow into the cooling air passageway.
