| 20220140665 | Power Generator Separating Multiple Electric Sources - A power generator includes a stator iron core and a rotor iron core rotatably mounted in the stator iron core. The stator iron core is at least provided with a first alternating-current (AC) supply unit and a second alternating-current (AC) supply unit separated from each other. The first AC supply unit includes a plurality of first coil windings connected with a first anode electric wire and a first cathode electric wire. The second AC supply unit includes a plurality of second coil windings connected with a second anode electric wire and a second cathode electric wire. The first coil windings to have a winding direction opposite to that of the second coil windings so that the first coil windings and the second coil windings do not interfere with each other. | 05-05-2022 |
