Abstract:
An electric machine comprises a frame, a cooling fan disposed in a fan housing and an integrated airflow inducer in a shape of a partial cone. The partial cone defines a skirt disposed as a differential sized ring with a larger entrance and a smaller exit around the frame of the electric machine at a boundary between the frame and the fan housing including a rotating fan to cool the electric machine. The integrated airflow inducer includes an inducer inlet and an inducer outlet. The integrated airflow inducer is configured to increase an airflow across the frame of the electric machine as the rotating fan develops a higher pressure at the inducer outlet than the inducer inlet of the integrated airflow inducer so that the integrated airflow inducer takes advantage of the high pressure to draw in air from a low pressure at the inducer inlet so that the electric machine operates at a lower temperature than without the integrated airflow inducer.
