Abstract: The invention provides systems and methods for cooling and lubrication of high power density electric machines with an enhanced fluid injection system. A plurality of fluid flow passages may be provided within the electric machine. A method for fluid distribution for cooling and lubrication of the electric machine may comprise providing a fluid distribution manifold with at least one inlet and a plurality of distribution openings leading to a plurality of fluid flow passages within the machine. The fluid within the electric machine may be used to cool and/or lubricate internal components of the electric machine.

Abstract: The invention provides systems and methods for power connection, which may be a sealed power connection. The sealed power connection may be used with an electric machine or any device that may require electrical and/or mechanical connection for power. The sealed power connection may provide an effective electrical connection while providing a robust mechanical connection. The electric machine or device may be fluid-sealed and/or fluid-cooled. The sealed power connection may provide for electrical insulation of the connection from the machine or device enclosure, and may also be sealed to provide for fluid sealing and/or internal fluid cooling of the electric machine or device, as well as fluid cooling of the connection.
