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.
Claims14
An electric machine comprising:
- a rotor fixed to a rotatable shaft and supported by means of one or more bearings;
- a stator stationary in relation to the rotatable rotor and shaft with a gap between the rotor and the stator;
- a housing surrounding all or part of the machine;
- and
- 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 that are in fluid communication with the rotor, stator, or housing, wherein the plurality of fluid flow passages includes one or more stator fluid flow pathways between the stator and housing directing fluid to flow circumferentially around the perimeter of the stator.
