Functioning and various information
Function of a starter motor on Subaru Impreza
The starter motor is an electric motor whose single function is to start the engine unit of your car. By a magnetic system and a “serial” technology, it will generate an enormous torque that will allow it to drive the pistons of the engine that are exposed 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 Subaru Impreza is activated and turns the drive pinion on the flywheel to start the engine.

Repeated attempts will pre-use your starter motor and if you do not resolve the trigger of your failure to start repeatedly, your starter may be the future part you will have to swap.
