An apparatus with an electric motor including a stator and a rotor; a shaft secured to the rotor; a gearing assembly coupled with the shaft; and a housing assembly defining a non-partitioned interior space housing both the electric motor and gearing assembly. The shaft may be unsupported by bearing assemblies and/or free of oil seals and similar sealing engagements between the electric machine and gearing assembly. The motor may be an axial flux motor having a single stator. The gearing assembly may be a planetary reduction gear assembly with a sun gear mounted on the shaft. The apparatus may include only a single electric motor or include a second electric motor and second gearing assembly. The embodiments having a single motor may be used to drive a fan or a vehicle wheel. The embodiments having two motors may be used as a differential drive.
