Can the car alternator be repaired if it breaks?

Introduction Can a car alternator be repaired if it is broken? If it is a minor fault in the alternator, it can be repaired by replacing parts. However, if the copper winding in the alternator is burned out, it is still repairable.

Can the car alternator be repaired if it breaks?

If there is a minor fault in the generator, it can be repaired by replacing accessories. However, if the copper winding in the generator is burned out, it is still recommended to replace it.

Because the cost of replacing a generator is actually not very high. If you adopt the method of replacing internal parts, it will not only take time but also get a new generator with only some parts. In this way It's a bit unnecessary.

Methods to determine whether the alternator is broken:

1. Use a multimeter to measure the battery voltage before starting the vehicle and after starting the vehicle. Generally, when the generator is working normally, the battery voltage reading is generally between 13V-14V. If it is lower than this reading, it may prove that the generator is not working;

2. Feel the operating temperature of the generator , if the temperature of the generator is very hot after the engine has been running for a period of time, it may have malfunctioned;

3. Observe whether there is any abnormal sound or jitter when the generator is working. If such a situation occurs It is possible that the belt tensioner or bearing is faulty.

Of course, this is just a simple way to judge the fault by ourselves. If you want a more accurate judgment, it is best to find a professional repair shop or 4S shop for inspection.

What will be the impact if the generator inlet air temperature is too high?

The difference between the maximum temperature of the generator winding and the generator inlet air temperature is long. When the generator is operating normally, the voltage is allowed to vary within the rated voltage range. The maximum allowable voltage for continuous operation of the generator shall not exceed the rated value. The minimum operating voltage of the generator shall be determined based on the requirements for stable operation. The maximum temperature of the generator windings The temperature difference with the generator inlet air temperature is long.

Hello (Yizhong Power Station) will answer for you:

If the generator wind temperature is too high, the stator coil temperature, iron core temperature, and rotor temperature will increase accordingly, causing insulation to occur. Embrittlement and weakened mechanical strength will greatly shorten the life of the generator. In severe cases, it may cause insulation damage, breakdown, and accidents;

Condensation will easily occur if the wind temperature is too low, and water droplets will condense on the generator. The insulation capacity of the generator coil is reduced, threatening the safe operation of the generator.
