What is the purpose of the starter motor?

The purpose of the starter motor is to turn the engine over. When you start a vehicle, the starter motor engages with the engine's flywheel, initiating the engine's internal combustion process. This action provides the necessary crankshaft rotation at startup, which is essential for the engine to draw in air and fuel and begin the cycle of operation. Without the starter motor performing this crucial task of turning over the engine, the vehicle would not be able to start and operate. This function is critical in the overall starting system of a vehicle, ensuring that the engine can begin running smoothly and efficiently.
