The Flywheel is also known as the rotating magnetic core, or Rotor, of an Alternator. Flywheels are the moving part in an Alternator that have permanent magnets that move around the Stator’s iron plates to generate an Alternating Current (AC). Made of a combination of carbon fiber and magnetic bearings, these systems can rotate as fast as 60,000 rotations per minute in industrial settings. Flywheels require existing motion to function, so only once the engine or turbine is already running will a Flywheel work with a Stator to provide a charge.
