Flywheel Energy Storage | Electric Vehicles Research
A flywheel is a rotating disk used as a storage device for kinetic energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based engine, or when the load placed on it is intermittent. Flywheels can be used to produce ...
