ABSTRACT:
An electrically motorized wheel assembly comprising a hollow shaft having a first opening at one end thereof and a second opening, the first opening receiving conductors from outside of assembly; a stator coaxial with and fixedly attached to the shaft; and a rotor coaxial with the stator and mounted for rotation about the stator, the rotor comprising a housing having a cylindrical wall having an inner surface provided with a magnetic means surrounding the stator and separated therefrom by an air-gap. The motorized wheel assembly also comprises a cylindrical filler made of a resilient material, the filler having a smooth outer surface and being waterproof, the filler being mounted around the housing, whereby the filler prevents presence of dirt and unwanted impurities between the housing and a rim fixed around an outer surface of the housing.
