    Duyunov wheel-hub motor

    I will clarify, but for now I will say. He loses by long-term power. It overheats when the weather is warm. Also remember all the problems of magnets. Fragile magnets, magnetic dust, collection of metal chips, power decreases with time, etc. There is no free rolling.
