United States: (12) Patent Application Publication (10) Pub. No.: US 2013/0043679 A1

This patent application describes a wind power generator that has two power generators. The first power generator generates electricity from the rotation of a rotor attached to a central rotation shaft. The second power generator generates electricity from the rotation of a flywheel attached to the rotation shaft through a one-way clutch. This allows the flywheel to continue rotating even if the rotation shaft speed decreases, powering the second generator. Electricity from either generator can be output. The generator aims to maintain power production even when wind speed decreases.

ABSTRACT

A wind power generator comprises a ?rst power generator


including a rotor arranged so as to be coaxial with a rotation
shaft and generates electric power by the rotation of the rotor,
a ?ywheel which is coaxial with the rotation shaft and
arranged through a one-way clutch so that when the rotation
shaft increases its speed, the ?ywheel is in an integrally rotat
ing state with the rotation shaft, and when the rotation shaft
