An electric motor includes a stator and a rotor movably disposed within the stator to define a gap therebetween. A central shaft extends outwardly from the rotor, and a bearing element is disposed in supporting relationship with the central shaft for providing bearing support of the rotor within the stator. A lubricant is disposed in the gap for providing additional or auxiliary lubricant support of the rotor within the stator. In an alternative arrangement, the central shaft is operably connected with a drive assembly, which is operably connected with a wheel hub assembly. In this arrangement, the bearing element is disposed in supporting relationship with the wheel hub assembly. In either arrangement, the wheel end electric motor includes both lubricant support as well as bearing support for optimizing performance of the electric motor in shock load environments.
