The basic design of an electric storage flywheel is to attach it to an electric engine and enclose it in a vacuum container to avoid air friction. To store energy, the engine provides motion to the disc/cylinder, increasing the rotational speed of the flywheel; the kinetic energy can later be drawn by the engine to generate electricity, this
Flywheel Energy Storage Systems convert electricity into rotational kinetic energy stored in a spinning mass. The flywheel is enclosed in a cylinder and contains a large rotor inside a vacuum to reduce drag. Electricity drives a motor that accelerates the rotor to very high speeds (up to 60,000 rpm). To discharge the stored energy, the motor acts as a generator,
