Abstract
An electric motor assembly includes a stator assembly and a rotor assembly positioned adjacent the stator assembly to define an axial gap therebetween. The stator assembly is configured to induce a first axial force on the rotor assembly. The electric motor assembly also includes an impeller directly coupled to the rotor assembly opposite the stator assembly such that the rotor assembly and the impeller are configured to rotate about an axis. A fluid channeled by the impeller induces a second axial force on the impeller. The electric motor assembly further includes a hydrodynamic bearing assembly including a rotating member coupled to the rotor assembly and stationary member at least partially circumscribing the rotating member such that rotation of the rotating member with respect to the stationary member is configured to induce a third axial force on the rotor assembly.
