Abstract: PURPOSE:To improve fuel consumption efficiency by rotatably providing a stator on the same shaft of a rotor, rotating the stator in the reverse direction with respect to the rotor at a reduced speed, thereby converting kinetic energy to electric energy and storing it. CONSTITUTION:A ring gear 6, with the inside of which a pinion gear 5 is engaged, is fixed to a shaft 1 so as to form a unitary body. The center of the pinion gear 5 is coincided with the rotating center of the shaft 1 and supported by a freely rotating disk 7. A sun gear 10, which is rotatably coupled with a stator coil 11 via clutch 9 which is rotated in one direction, is engaged with the shaft 1. The disk 7 is braked by a brake cylinder 13. When the disk 7 is braked at the time of speed reduction, the rotation of the ring gear 6 is increased in the reverse direction via the pinion gear 5 and transmitted to the sun gear 10. Since said rotation is transmitted to the stator coil via the clutch 9 which is rotated in one direction, the direction of the stator rotation is opposite to the roto 4, and the relative speed becomes several times faster than normal speed.
