[0002] A flywheel is a disc-shaped part with a large moment of inertia. It acts as an energy storage device and is an essential part of the engine. With the rapid development of the automobile industry, the demand for flywheels is increasing. The motor drives the large mass flywheel to rotate at high speed, and the kinetic energy is stored through the inertia of its high-speed operation.
