alternator

Engine-driven dynamo

An alternator is an electrical generator that produces alternating current, typically driven by a belt connected to an engine.

In cars, the alternator charges the battery and powers electrical systems while the engine runs: The mechanic said my alternator needs replacing.

The term distinguishes it from generators that produce direct current.
