The functions of automobile generator are as follows:

1. When the engine is running normally, supply power to all electrical equipment except the starter and charge the battery at the same time. The generator is the main power supply of the vehicle.

2. Automobile generator is composed of rotor, stator, rectifier and end cover, which can be divided into DC generator and AC generator.

The following are the precautions for the use of automobile generator:

1. Always clean the dirt and dust on the surface of the generator and keep it clean and well ventilated.

2. Regularly check the fastening of all fasteners related to the generator and fasten all screws in time.

3. If the generator fails to generate electricity, it shall be eliminated in time.

“The main function of the stator assembly and rotor assembly of the automobile alternator is to generate electromotive force at both ends of the conductor. The function of the stator coil is to generate three-phase alternating current, and the rotor coil is used to generate rotating magnetic field.”

1. The generator does not operate according to the specified technical conditions, such as the stator voltage is too high and the iron loss increases; If the load current is too large, the copper loss of stator winding increases; The frequency is too low, which slows down the speed of the cooling fan and affects the heat dissipation of the generator; The power factor is too low, which increases the excitation current of the rotor and causes the rotor to heat. Check whether the indication of the monitoring instrument is normal

2. The three-phase load current of the generator is unbalanced, and the overloaded one-phase winding will overheat; If the difference of three-phase current exceeds 10% of the rated current, it is a serious cricket phase current imbalance. The three-phase current imbalance will produce negative sequence magnetic field, increase loss and cause heating of pole winding, ferrule and other parts. The three-phase load should be adjusted so that the current of each phase

3. The air duct is blocked by dust and the ventilation is poor, which makes it difficult for the generator to dissipate heat. Dust and oil dirt in the air duct shall be removed to make the air duct unobstructed.

4. The air inlet temperature is too high or the water inlet temperature is too high, and the cooler is blocked. The inlet air or inlet water temperature shall be reduced and the blockage in the cooler shall be removed. Before the fault is eliminated, the generator load shall be limited to reduce the generator temperature
