So, a car starter motor is an electric motor, that turns over or “cranks” the engine to start it.
But, to turn over the engine, the starter also requires, a very high electric current.
So, if the battery is low, the lights in a car might come on. But, it won’t be enough power, to turn over the car starter motor.
Consequently, starting system problems are common. But, a faulty car starter motor, may not be the cause of all of them.
How your starter works
Your starter is really an electric motor. It engages, when you turn the ignition to “run” and turns the engine over, allowing it to suck in air.
- Attached to the back of the crankshaft, is a flex-plate or flywheel, with a ring gear around the edge.
- On the car starter motor, there’s a starter gear, designed to fit into the grooves of the ring gear.
- When you turn the ignition switch, the starter motor is energized, and the electromagnet inside the body engages.
- This magnet, pushes out the starter drive gear.
- The gear meets the flywheel, and the starter turns.
- This spins the engine over, sucking in air (as well as fuel).
- At the same time, electricity is sent through the spark plug, igniting the fuel in the combustion chamber.
