Generators can be divided into DC generators and alternators. Since alternators are superior to DC generators in many ways, DC generators have been eliminated. Currently, all cars use alternators. The classification method is divided into the following categories:
Five categories according to the overall structure
(1) Ordinary alternator (generator that requires a voltage regulator when used)
(2) Integrated alternator (the generator and regulator are transformed into an integrated generator)
(3) Alternator with pump,
< p>(4) Alternator brushless (generator that does not require brushes)(5) Permanent magnet alternator (generator with magnetic poles made of permanent magnets)
Four categories according to the structure of the rectifier
(1) Six-tube alternator
(2) Eight-tube alternator

(3) Nine-tube alternator Alternator
(4) Eleven-tube alternator
Two categories according to the magnetic field winding grounding form< /p>
(1) Internal grounding type AC generator One end (negative pole) of the machine field winding is directly grounded (connected to the case)
(2) One end (negative pole) of the externally grounded alternator field winding is connected to the regulator, and the regulator then takes the train.
