A flywheel is a heavy disk-like structure used in machinery which acts as a storage device to store energy when energy input exceeds demand and releases energy when energy demand exceeds supply. In steam engines, internal combustion engines, reciprocating compressors, and pumps, energy is produced during one stroke, and the engine is designed to run the entire cycle with the energy produced during that one stroke.
