A preliminary understanding of generators with common sense in automotive electrical equipment assembly

　Automobile generators are the main power supply for cars. The function is to supply power to all electrical equipment and charge the battery when the engine is operating normally.
　　Introduction
　　With the advancement of automotive technology, the electricity consumption of cars is getting higher and higher. 20 years ago, the generator output power of intermediate cars
　　was generally only about 500 watts of automobile generators, and now the generators of intermediate cars are generally around 1,000 watts. The increase in generator power increases with the increase in electrical equipment used in the vehicle. Nowadays, generators on cars are air-cooled generators, which are blown into the case by the fan behind the pulleys for cooling. Under the limitations of existing air-cooled power generation mechanisms, the increase in power will inevitably lead to an increase in the generator volume.
　　Functional
　　generators are the main power supply for cars. The function is to supply power to all electrical equipment and charge the battery while the engine is operating normally.
　 Classification
　　Automotive generators can be divided into DC generators and alternators. Since alternators are better than DC generators in many aspects, DC generators have been eliminated. Currently, all cars use alternators. Alternative generators are divided into the following categories according to different classification methods:
　　1. According to the overall structure, five categories
　　of automotive generators. Examples of JF132
　integrated alternators. Examples of Buick cars. The engine is equipped with CS generators
　　with pump alternators. Examples of JFZB292 generators.
　　Brushless alternator example JFW1913
　　permanent magnet alternator
　　2. According to the rectifier structure, four categories,
　　six tube alternator example, JF1522
　　eight tube alternator example, JFZ1542
　　nine tube alternator example,
　　eleven tube alternator example, JFZ1913Z
　　3. According to the grounding form of magnetic field winding,
　　one end of the inner ground type alternator magnetic field winding is directly grounded
　　, and one end of the outer ground type alternator magnetic field winding is connected to the regulator, and then the iron is grounded after passing through the regulator.
