When I took my courses on electrical machines, it always said about cylindrical rotors surrounded by cylindrical stators. Well, I have been thinking about situating the statoric electrical poles conveniently over an sphere surface. One technological application of this would be the next. Imagine I substitute the entire thermal engine, transmission shafts, and the four tyre wheels of a car, by "four spherical tyre wheels", magnetically well designed, such the statoric poles that cover them fixed in a statoric spherical structure could rotate the rotors in any direction. The stator couldn't be complete spherical, but it would have a part cut in order to allow a road-rotor contact. Can you see my vision?. Shafs, engines, pinions, pistons, air pipes, inyection systems, all of this heavy inertial masses could be depleted and substituted by two electrical engines, their batteries, converter, electronical conmutators. Ok, guys, try to break up my proyect, If you can.
