Patent ID: 8558422

Claim:
A liquid-cooled stator and rotor assembly for use as an electric motor or generator, the liquid-cooled stator and rotor assembly comprising: a housing having a first end bell, a second end bell, and at least one fluid orifice in the first end bell; a stator fixed within a stator cavity of the housing, the stator including a stator core and a plurality of windings for conducting a flow of electricity; a rotor for magnetically interacting with the stator, the rotor being rotatably mounted between the first end bell and the second end bell, and being positioned within a rotor cavity; and a first sealing ring adjacent the first end bell and a second sealing ring adjacent the second end bell, each sealing ring being adapted to form a fluid seal against the respective end bell and against a portion of the stator such that a cooling fluid entering the stator cavity via the at least one orifice does not substantially enter the rotor cavity.
