Abstract
An electric machine includes a housing having an air intake, an air outlet, and defining an air passage therein. The air passage includes a first channel extending from the air intake in a radial direction and a second channel extending in the radial direction to the outlet. The electric machine further includes a motor assembly positioned within the housing that includes a shaft that rotates about a rotational axis that is generally perpendicular to the radial direction. The electric machine further includes an electronics assembly within the housing interior and a heat sink positioned at least partially within the air passage and thermally connected to the electronics assembly. Operation of the motor assembly draws an ambient airflow into the air passage in the radial direction through the air intake, directs the airflow along the heat sink, and exhausts the airflow through the air outlet in the radial direction.
