Although the starter and the alternator are essential parts of a car’s electrical system, they operate in distinct ways and serve separate functions.
Structure
The starter is a motor that starts the engine, whereas the alternator is a generator that generates electricity to charge the battery and operate the vehicle’s entire circuit.
Components
The starter comprises a battery, a solenoid, and an electric motor, whereas the alternator includes a rotor, STARTER MOTOR , and voltage regulator.
Function
The starter’s primary duty is to get the engine to turn over to begin the vehicle. In contrast, the alternator’s primary function is to create electrical power to replenish the battery and power the car’s electrical system.
Conclusion
Despite being both essential components of an automobile engine, the alternator and starting motor serve distinct purposes. The alternator creates power, whereas the starting motor consumes electricity. These engine elements utilize and produce electricity, but they perform different tasks in the cycle. The starter’s primary duty is to get the engine to turn over to begin the vehicle. In contrast, the alternator’s essential task is to create electrical power to replenish the battery and power the car’s electrical system.
