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.
