How does a starter motor work?
Answers:
a starter motor is a simple electric motor with a spring gear at one end.
when you engage the motor it spins forcing the gear into a large cog on the flywheel which turns the main engine to get it started.
the starter motor stops and the spring gear releases while the main engine fires and turns (hopefully)
Find a mechanic to explain that to you. ask me about computers, then you will have a correct answer. great day
.unless it is a pre-engaged starter motor (there are two types), in which case a solonoid (elecrtomagnet) forces the little gear into the big gear on the flywheel of the engine before the electric motor makes the engine go round.
The engine must be turning to make it work, or it can't suck in the fuel or get up the pressure to make the fuel burn correctly. The engine needs the electric motor to make it turn.
Hopefully this is not too confusing for you.

You close the electr.chain w. the key
There is a complete system relating to the starter. It starts with the battery, which a lead runs down to the starter solenoid, then there is a lead from the solenoid that goes to ground. You have a starter relay, which has a wire to the ignition switch, a wire to the solenoid, a wire to the nuetral start switch of the transmission. When you key the starter, there is a constant "hot" on the switch, when you move the key to start, it closes a 12 volt circuit to the relay, which closes another switch that sends 12 volts to the solenoid, and the motor. When the solenoid is energized, it moves a fork inside the casing that engages a gear on the starter motor, the gear moves to the rear to engage the flywheel of the engine, which makes it turn the crankshaft and start the ignition system of the engine, thus starting the car.
