When it comes to powering your car's radio, headlights, and other electronic components, you may think the battery puts in all the work. In reality, it's your alternator that keeps things up and running. But what exactly does an alternator do, and how does it work?
On average, an alternator lasts 7–10 years or about 80,000 to 150,000 miles, depending on driving habits and vehicle type. Can I drive with a bad alternator? Not for long. A failing alternator can cause your battery to die quickly, leaving you stranded.
Your car's alternator generates electricity by converting mechanical energy from the engine into electrical energy. When the engine runs, it spins a belt connected to the alternator, which turns a rotor inside. This motion creates alternating current (AC), which is converted into direct current (DC) to power your car's electrical systems.
The main components of the alternator and their functions are the following: Pulley: Transfers mechanical energy from the engine to the alternator. Rotor: Creates the magnetic field used to generate an alternating current. Stator: This is the static part of the alternator where the voltage is generated.
If it''s time for an alternator replacement, NAPA Auto Parts carries a vast supply of alternator repair kits, condensers, bracket clamps and even rectifiers and brushes for all your alternator repair or
