Title: System of generating electricity while maintaining constant number of revolution of flywheel
Inventor: FURUKAWA CHOJI
IPC: H02K7/20
Filed: 2018-05-17
Abstract: To minimize energy consumption by keeping the number of revolution of a flywheel at a constant set number of revolution, thus allowing long time electricity generation, rotation of the flywheel slows down due to the loads, such as air, bearing, the generator, and the like, but it is dealt with by a speed changer by always changing the power usage.SOLUTION: The number of revolution of a flywheel is kept at a constant set number of revolution by a small geared high rotation small power motor so that rotation of the flywheel is not stopped, thus preventing the flywheel generator from decreasing the number of revolution with time or stopping. Power usage always changes, but since the number of revolution of the flywheel of the flywheel generator system is constant, a speed changer is built in between the flywheel and the generator and the number of revolution inputted to the speed changer is changed.SELECTED DRAWING: Figure 1
