What Is an Automotive Starter Motor and How Does It Work?
An automotive starter motor is an essential component in a vehicle’s ignition system responsible for initiating the engine’s operation. When the ignition key is turned or the start button is pressed, the starter motor engages with the engine’s flywheel to crank the engine and start the combustion process. It converts electrical energy from the vehicle’s battery into mechanical energy, providing the necessary torque to turn over the engine.
Starter motors typically consist of an electric motor and a solenoid. The solenoid acts as a switch that connects the motor to the battery and simultaneously pushes the starter gear to mesh with the engine’s flywheel. Once the engine starts running, the starter motor disengages automatically to avoid damage. Reliable starter motors are crucial for smooth and quick engine startups and are used in almost all internal combustion engine vehicles, including gasoline, diesel, and hybrid models.
