Abstract
A flywheel includes a shaft a rotor attached to the shaft. The rotor rotates using the shaft as a central axis. The rotor includes at least one magnet along an outer circumferential surface thereof, at least one coil spaced apart from the rotor in a radial direction. The coil may form a magnetic field that exerts a magnetic force on the magnets when current is supplied to the coil by an electric circuit, thus mitigating fluctuations in rotation of the rotor.

An apparatus, comprising:
- a plurality of blades coupled to a rotation center body;
- an electric generator configured to generate electricity when the rotation center body rotates;
- a flywheel including a rotor coupled to the rotation center body, and a magnet attached to an outer surface of the rotor;
- and
- a trigger coil spaced apart from the rotor in a radial direction and coupled to an electric circuit;
- the trigger coil configured to exert a magnetic force on the magnet when the electronic circuit supplies the trigger coil with current,
- wherein the magnet is one of a plurality of magnets disposed on the outer surface of the rotor, each of the plurality of magnets having an N-pole pointed radially from the rotor.

A method of rotating a rotor, comprising:
- generating an attractive magnetic force between a trigger coil and a magnet attached to the rotor by inducing a first current signal in a trigger coil when the magnet approaches the trigger coil;
- and
- generating a repulsive magnetic force between the trigger coil and the magnet by inducing a second current signal in the trigger coil when the magnet passes the trigger coil,
- wherein the magnet is one of a plurality of magnets disposed on an outer surface of the rotor, each of the plurality of magnets having an N-pole pointed radially from the rotor.
