Abstract:
1. A cooling system for an ancillary component of an electric machine comprising: a pumping element configured to urge an airflow across a plurality of permanent magnets of a rotor of the electric machine to remove thermal energy therefrom; a plurality of cooling channels disposed in a housing of the electric machine configured to transfer thermal energy from a stator of the electric machine to a flow of fluid coolant through the plurality of cooling channels; a heat exchanger in thermal communication with the plurality of cooling channels to transfer thermal energy from the airflow to the fluid coolant; one or more coolant supply conduits extending from the electric machine to the ancillary component to divert a portion of the airflow from the heat exchanger to an ancillary component of the electric machine to allow for transfer of thermal energy from the ancillary component to the airflow; and one or more power leads extending through the one or more coolant supply conduits to operably connect the ancillary component to the electric machine.
