(EN) POWER GENERATOR
要約
(EN)

A power generator produces electromotive forces in the same direction on all windings to prevent lowering of rotational forces of rotor plates due to magnetic fields. The generator includes first windings divided in plural number and wound around a fixed ring core in opposite directions. Second windings having the same constitution as the first windings are wound at 45° to the first windings. Capacitors are connected to one end of each of the first and second windings. A first rotor plate having first permanent magnets is provided on one surface of the ring core and a second rotor plate having second permanent magnets is provided on the opposite surface of the ring core. The two rotor plates are provided on a driving shaft so that the same magnetic poles thereof oppose each other and rotate to output electricity generated on the first and second windings via the capacitors.
