Operation Principle of Automobile Generator

Operation Principle of Automobile Generator
The working principle of automobile AC generator is based on electromagnetic induction. When the engine is running, the AC generator rotor rotates through the belt. When the excitation winding on the rotor is energized, a magnetic field is generated, which magnetizes the salient poles into N poles and S poles. When the rotor rotates, its magnetic field cuts the stator winding, generating an alternating induced electromotive force in the stator winding, thereby outputting AC power. Then, the rectifier inside the AC generator converts the AC power into DC power to power the car's electrical system and battery.

Common types of starters

Common types of starters

Direct manipulation type: Directly controls the starter circuit through foot pedals or hand levers. The structure is simple but inconvenient to operate, and is now rarely used. Electromagnetic manipulation type: Controls the starter circuit through an electromagnetic switch. It is convenient to operate and is widely used in modern automobiles.
