The purpose of the invention is to prevent power loss due to centrifugal force and other forces by forming the rotating portion of a motor or a generator into a circular or multi-angular rotating structure having two shafts or multi-shafts and to drastically increase power in such a way that the coils and magnets of the motor or the generator, which conventionally have a single layer structure, are formed into a multi-layer structure or are enclosed so as to be wound. The total amount and weight of the magnets can also be reduced, so that lightweight can be achieved. Further, a large magnetic force body is provided together as an aid to the magnetic force of the generator or the motor. A large magnetic force is transferred to a rotor and a stator by making contact with or not making contact with this large magnetic force body. More power can thereby be obtained. Reducing the weight of the rotor also generates a large amount of electric power or generates a large amount of power. The output of the motor or the generator is reasonably enhanced, which serves for achieving energy saving, small size and high output, and reduction of weight. A permanent power generation by the power-up method described above and a magnetic force shielding control and another permanent power generation by magnetic attraction removal or a magnetic repulsion control serve for solving an energy problem.
