Abstract: In a lubrication and cooling system for an electric machine operably driven by a turbine, a rotatable shaft may extend through an electric machine housing and a first and second bearing may be operably spaced apart from each other and coupled to the rotatable shaft. Furthermore, an electromagnetic rotor may be coupled to the rotatable shaft and disposed between the first and second bearings. A stator may be fixedly attached within the electric machine housing such that the electromagnetic rotor freely rotates along with the rotatable shaft. Additionally, a fluid passage defined in the electric machine housing delivers a portion of fluid to lubricate the first and second bearings and the remaining portion of fluid to circumferentially flow around the stator such that the fluid is in thermal communication with an outside surface of the stator to help maintain a desired operating temperature of the electric machine.
