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.

Abstract: A number of variations may include a product comprising: a turbomachinery device comprising: an electric motor surrounding a portion of a shaft constructed and arranged to selectively drive the shaft in rotation about a rotational axis, wherein the electric motor further comprises a stator comprising a lamination stack; a housing surrounding the electric motor, wherein the housing includes a plurality of channels constructed and arranged to lubricate a first bearing; and wherein the lamination stack includes at least one retention component wherein the retention component is constructed and arranged to locking the stator in an axial direction while locking rotation of the stator about the rotational axis and wherein the retention component further comprises at least one conduit constructed and arranged to pass fluid through the electric motor to a second bearing.

Abstract: A turbocharger with a turbine (10) having a turbine wheel (12) in a turbine housing (14) with an associated manifold (24) having individual ports (22) corresponding to unobstructed passageways (26) from each cylinder of an engine. The ports (22) are substantially equally spaced around a face of the turbine wheel (12) to preserve benefits of pulses without interference.

Abstract: A number of variations include a product including system including a fluid circuit comprising a fluid, a pump, an expander, a power generation component, at least one heat exchanger, and a condenser, wherein the condenser is constructed and arranged to be mounted in the path of ram air on a vehicle; and an attachment for attaching at least the condenser to the vehicle in the path of ram air. In a number of variations, the system may include an Organic Rankine Cycle (ORC) system in a vehicle to convert waste heat energy to usable power where the condenser of the ORC system is housed within the fairing on the vehicle cabin roof to ensure placement within the path of ram air on the vehicle.
