Abstract
A liquid-cooled stator and rotor assembly for use as an electric motor or generator includes a housing having a first end bell, a second end bell, and at least one fluid orifice in the first end bell. A stator is fixed within a stator cavity of the housing. The stator includes a stator core and a plurality of windings for conducting a flow of electricity. A rotor for magnetically interacting with the stator is also included, the rotor being rotatably mounted between the first end bell and the second end bell within a rotor cavity. A first sealing ring and a second sealing ring are provided to form a fluid seal against the respective end bells and against a portion of the stator such that a cooling fluid entering the stator cavity via the orifice does not enter the rotor cavity.
