2. The forms of automobile generators include: DC generators and alternators, which are divided into synchronous generators and asynchronous generators (rarely used); alternators can also be divided into single-phase generators and three-phase generators. There are many kinds of generators.
3. Automobile generators can be divided into DC generators and alternator generators. Because alternators are superior to DC generators in many aspects, DC generators have been eliminated.
The following is a list of specific elimination plans for each failure: the charging current is too small: when the battery storage capacity is insufficient and the engine speed increases, the ammeter refers to The needle indicates that the charging current is small, indicating that the charging current is too small.
Troubleshooting: Find the leak, re-seal or replace the phase parts. Troubleshooting of the fuel injector: clean the fuel injector, check the fuel injection volume of each fuel injector and confirm that there is no blockage or dripping.
High-speed electric shock sintering, contact cauterization, and adjustment of the resistance segment at the same time; (2) The voltage regulator of the transistor voltage regulator is short-circuited or the power triode is open; the grounding method of the regulator does not match the generator. The troubleshooting method steps are as follows: 1) Check the tightness of the belt and the connection of the wire (looseness or error) in turn.
should respond; the battery is seriously out of power in the later stage, and the starter cannot work at startup. [ Reasons why automobile generators do not generate electricity] Common reasons why alternators do not generate electricity: (1) The diode is penerced and cannot be rectifyed.(2) The electric card is in the grip, and the generator cannot generate electricity due to non-excitation.
The unstable voltage of automobile generators has the following analysis and solutions. Analysis of the causes of voltage instability of automobile generators. The contact point between the generator stator and the carbon brush is dirty, resulting in the instability of the excitation voltage, and the output of alternating current is also unstable.

2. The gasoline engine drives the generator to run and converts the energy of gasoline into electricity.In the cylinder of the gasoline engine, the mixed gas burns violently, and the volume expands rapidly, pushing the piston down to work.
3. The working principle of the automobile generator is that when the external circuit energizes the excitation winding through the brush, a magnetic field is generated, so that the claw pole is magnetized into n poles and s poles. When the rotor rotates, the magnetic flux changes alternately in the stator winding. According to the principle of electromagnetic induction, it can be seen that alternating induced electromotive potential is generated in the three-phase winding of the stator.
