What component of an internal combustion engine is rotated by the electric starter motor?

The flywheel is the component of an internal combustion engine that is rotated by the electric starter motor. When the starter motor is engaged, it provides the initial rotational force needed to turn the flywheel. The flywheel is a heavy, disc-shaped component attached to the crankshaft that helps store rotational energy and smoothens out the power delivery from the engine during its operation.

The electric starter motor connects to the flywheel and, once activated, spins it to start the engine's cycle. This rotation of the flywheel allows the crankshaft to begin turning, which subsequently initiates the movement of the pistons in the engine cylinders.

While camshaft and crankshaft are essential for engine operation, they do not directly interface with the electric starter motor as the flywheel does. The piston, on the other hand, is a component that moves within the cylinders and relies on the crankshaft's rotation generated by the flywheel to move up and down, facilitating the engine's cycle.
