Starter motors are electrical motors used to rotate an internal combustion engine so as to initiate the engine's operation under its own power. That said, whilst starter motors are usually only used within the first few moments of a vehicle's journey, they are very important components indeed.
The modern starter motor tends to comprise a series-parallel wound direct current electric motor with a starter solenoid mounted on it. When the ignition key is turned in the cockpit, current from the starter battery is applied to the solenoid which engages a lever which subsequently pushes a drive pinion on the starter driveshaft into an engaged position within the starter ring gear of the engine flywheel.
The starter motor begins to turn when the high current contacts are closed by the solenoid. Once the engine has started, a spring within the solenoid pulls the pinion gear from the ring gear and the starter motor stops. At this point, the starter motor has fulfilled its purpose.
Of course, starter motors develop faults as they age and it is often necessary for them to be replaced.
