  • Electric machine cooling system
    Patent number: 9698638
    Abstract: A cooling system for an electric machine is provided. The cooling system includes an airflow diverter feature configured to provide even distribution of airflow to the electric machine. The airflow diverter feature includes a circular disk mounted to the housing of the electric machine. The disk defines a plurality of vents forming an axial air passage. A plurality of radial air passages are in fluid communication with the axial air passage. The airflow diverter feature defines at least one inlet and at least one outlet. The inlet comprises at least one interior choke and the outlet comprises at least one exhaust choke. The interior choke and the exhaust choke are sized to control a rate of air flow through the radial air passages.
