Abstract

The present invention discloses a power-saving electrical device, which employs a mechanical power system energized by an initial power supply to rotate a flywheel. Due to the principle of inertia, the flywheel enables the mechanical power system to provide a large torque. The flywheel is connected to an electrical generator so that the mechanical power system can drive the electrical generator to generate a large amount of electrical power, thus achieving the effect of energy saving. In addition, surplus power at the electrical generator can be fed back to a power storage device, which has the function of providing electrical power to initiate the mechanical power system.
