FLYWHEEL AND ITS TYPES

  FLYWHEEL AND ITS TYPES   What is a flywheel? A flywheel as a weighty wheel requires enough forces to rotate on its axis. It resists changes in rotational speed by their moment of inertia. Changing the stored energy on the flywheel, its rotational speed must be increased or decreased. That is, it keeps spinning until lots of force is applied. A great amount of kinetic energy is preserved when the flywheel rotates. This energy is later used to power up the vehicle when starting the engine or speeding.   Construction of a flywheel Due to the toughness requirement of a flywheel, it is typically made of steel that rotates on conventional bearings. High energy density flywheels are made of carbon fibre composites and use magnetic bearings. Such flywheel revolves at speed up to 60,000 RPM (1 kHz).   Functions of Flywheel Flywheels can be found in almost all types of automobiles as they serve a variety of purposes will be discussed here. Below are the functions of the flywheel in an automobi
