Abstract
An electric machine includes a rotor located at and rotatable about a central axis and a stator positioned proximate to the rotor and defining a radial machine gap between the rotor and the stator. A cold plate is positioned proximate to the rotor. The cold plate is rotationally stationary relative to the central axis and is spaced apart from the rotor to define a cold plate gap between the cold plate and the rotor. The cold plate includes one or more coolant pathways therein such that thermal energy from the rotor is transferred to a flow of coolant circulated through the one or more coolant pathways.
