The apparatus according to the present invention comprises three independent complementary brush-less variable speed electric motor generators having a common stator with three radial and lateral electromagnets, which are interfaced to a complementary rotor with permanent magnets installed within a magnetic field containment frame as a means provide a virtual self- centering electromagnetic bearing for the power ON mode of operation. A pair of radial and lateral roller bearings provides support for the wheel in the power OFF mode of operation. Two sealing rings between the stator and rotor, and an "O" ring in the outer rim of the rotor covers form a watertight assembly. The rotor forms a tire rim that adapts to conventional tubeless tires fitted with a flat and blowout proof multi closed cell assembly and a tire compression rim to facilitate tire exchange. A conventional hydraulic foot operated drum brake like system, which is manually and electrically interfaced, in addition of electromagnetic braking by automatic computer control, is adapted to the front-side of the rotor and stator. An integral stator rear heat sink is cooled by forced air induced by slanted vanes in the rear rotor- cover, to provide a heat pump for the electromagnets by thermal conduction. A decorative cover is installed over the stator assembly, which is interfaced to a stationary mounting plate in the vehicle, having threaded stud bolts matching the drillings in the stator.
