Alternator Components
The alternator in your 2002 Toyota Camry consists of several different components that work together to produce electrical current for your vehicle. These components include:
| Component | Description |
|---|---|
| Stator | Produces AC voltage as the rotor moves past it. |
| Rotor | Consists of a magnet and spins within the stator, creating a magnetic field that produces AC voltage in the stator. |
| Diodes | Convert AC current to DC current for use by the vehicle’s electrical system. |
| Voltage Regulator | Regulates the output voltage from the alternator to maintain a consistent charge for the battery. |
Understanding the function of each of these components is essential for troubleshooting any issues you may be experiencing with your 2002 Toyota Camry alternator.
