Function of a starter motor on Audi S5

By a magnetic system and a “serial” technology, it will launch an enormous torque that will allow it to drive the pistons of the engine that are subjected to enormous compression and an oil that provides additional resistance being not very fluid when cold.
It is completed by the “solenoid”. It is an electromagnet that goes under a 12 volt electric impulse to push the fork (link part between the “solenoid” and the electric motor of the starter) and thus engage the starter drive pinion on the engine flywheel. Following this action, once in engagement, the starter motor of your Audi S5 is activated and turns the drive pinion on the flywheel to start the engine.
