What is a Starter Motor?
The muscle that turns your engine over when you twist the key.
Simplified animation — not to scale.
In plain English
The starter motor is a powerful electric motor that spins the engine fast enough for it to fire up. Once the engine is running, the starter disengages.
A simple analogy
"Like the pull cord on a lawnmower — it gets things spinning, then steps aside."
How it works
When you turn the key (or press start), the battery sends a burst of current to the starter. A small gear pops out, meshes with the engine's flywheel, and cranks it round.
