An electromotive wheel of which a rotor is attached to the wheel frame and a stator is attached on the the wheel axle. As power has been supplied, the induction electromagnetic field is induced in either the rotor or the stator. When a brake element is fixed on the wheel axle and released as the current is interrupted, then the rotor and the stator are rotated around the wheel axle by the magnetic force of the permanent magnet; but under the condition of supplying power, the brake element brakes the stator located on the wheel axle, thus the stator and rotor produce relative rotation induced from the induction electromagnetic force to drive the wheel frame.
