2. Balancing machine - Wikipedia

   en.wikipedia.org/wiki/Balancing_machine

   The latter being required when the rotor has a high service speed, or critical application (see ISO 201940 for recommended balancing tolerance.) Hard- and soft-bearing machines can be automated to remove weight automatically, such as by drilling or milling, but hard-bearing machines are more robust and reliable.

3. Balancing of rotating masses - Wikipedia

   en.wikipedia.org/wiki/Balancing_of_rotating_masses

   Under conditions where rotating speed is very high even though the mass is low, as in gas turbines or jet engines, or under conditions where rotating speed is low but the mass is high, as in ship propellers, balance of the rotating system should be highly considered, because it may generate large vibrations and cause failure of the whole system.

4. Flywheel energy storage - Wikipedia

   en.wikipedia.org/wiki/Flywheel_energy_storage

   NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...

5. Rotating unbalance - Wikipedia

   en.wikipedia.org/wiki/Rotating_unbalance

   A static balance (sometimes called a force balance [2] [3]) occurs when the inertial axis of a rotating mass is displaced from and parallel to the axis of rotation.Static unbalances can occur more frequently in disk-shaped rotors because the thin geometric profile of the disk allows for an uneven distribution of mass with an inertial axis that is nearly parallel to the axis of rotation.

6. Governor (device) - Wikipedia

   en.wikipedia.org/wiki/Governor_(device)

   A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...

7. Flywheel - Wikipedia

   en.wikipedia.org/wiki/Flywheel

   Trevithick's 1802 steam locomotive, which used a flywheel to evenly distribute the power of its single cylinder. A flywheel is a mechanical device that uses the conservation of angular momentum to store rotational energy, a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed.
