What is a starter motor?

On turning the ignition on, the starter motor connects and turns the engine over permitting it to pull in air and fuel. The flywheel on the engine has a ring gear connected around the edge that is fitted to the end of your crankshaft.

On the starter, the pinion is constructed to fit into the grooves of the ring gear. When you turn the ignition switch, the electromagnet inside the component engages and pushes out a rod to which the pinion is attached.

Like every car part, the starter motor can be damaged due to usual wear and tear. Usually failure is down to bad solenoid valves within the motor. Most faults with the starter motor can be repaired, but in some cases, the technician may advise that the starter motor needs to be replaced.
