Abstract
A flywheel power source device for converting electric energy into kinetic energy and for storing the kinetic energy by rotating a flywheel of which rotary shaft is rotatably supported by a bearing mounted in a casing at high speed, wherein the kinetic energy is reconverted into electric energy when necessary; the flywheel power source device is provided with a rotational fulcrum at a bottom of the rotary shaft and a center of gravity of the flywheel being positioned on a line of action of a resultant force of magnetic attractive forces acting on the flywheel.
Claims4
A flywheel power source device for converting electric energy into kinetic energy, for storing kinetic energy, and for reconverting kinetic energy into electric energy when necessary, comprising:
- a casing;
- a flywheel configured to rotate at a selected speed within said casing;
- a rotary shaft for supporting said flywheel;
- a bearing mounted in said casing and rotatably supporting said rotary shaft;
- and
- a rotational fulcrum at a bottom end of said rotary shaft;
- wherein said flywheel has a center of gravity positioned on a line of action of a resultant force of magnetic attractive forces acting on said flywheel, said line of action acting on said rotational fulcrum at said bottom end of said rotary shaft.
