How does a car generator generate electricity?

How does a car generator generate electricity? Automobile generator is the main power source of automobile. Its function is to supply power to all electrical equipment (except starter) and charge the battery when the engine is running normally (above idle speed). When the switch is closed, the battery provides current first. Circuit: positive battery → charging indicator light → regulator contact → excitation winding → grounding → negative battery. At this point, the charging indicator light will light up because there is current flowing. Automobile is a compound circuit of "double power supply". When the engine is not started, the power of the whole vehicle is provided by the battery. When the engine is started, the whole vehicle point is jointly powered by the battery and the generator (when the engine speed is lower than the requirements of the generator, the battery provides electric energy). When the engine speed is higher than the required generator speed, the generator charges the battery. When the battery voltage rises to 13.8- 14.2V (battery charging termination voltage), the generator regulator cuts off (or reduces) the excitation, so that the vehicle voltage can be stabilized at this voltage, which is beneficial to battery charging. Next, discharge. @20 19
