How to judge the quality of car alternator

You mentioned that the battery died, which is not necessarily a problem with the generator. Usually, a van's battery will have aging issues after two years of use. After aging, the internal resistance is very high and. it cannot be fully charged for a long time. Start the engine at this time, the internal resistance will prevent the engine from rotating. Additionally, the battery terminals are prone to the formation of white crystals, which can also lead to poor battery charging and difficulty starting the engine. You can pour hot water over 70 degrees onto the terminals. The crystals will melt and be washed away by the water. Get off, it's best to use a wrench to unscrew the fixing screws and scrape the terminals clean. As for whether there is a problem with the generator, you can judge it as follows: start the engine at the nuit, maintain the engine speed at approximately 2000 rpm, turn on the headlights, observe the brightness of the headlights, then turn on the air. air conditioner, then observe the brightness of the headlights. If the brightness drops significantly after turning on the air conditioner, there may be a problem with the generator. If you want to know more precisely, you can install a digital voltmeter. This instrument is inexpensive and can help you accurately assess the battery or generator problem. Measure the voltage of a good battery half an hour after it is fully charged. Between 12.4V and 12.8V, although it can be started at a slightly lower level, it cannot be lower than 11.7V. After starting the motor, if the voltage is between 13V and 16 V, the generator is intact.

How does the electric vehicle motor get water?

Your 2.2 kW generator may have insufficient power, a faultsse standard, etc.

Consequently

The load is too high

The virtual 2.2 kW are not enough to support 3 times the starting current when the water pump starts

The current exceeds the maximum limit of the generator circuit breaker

So it trips Protected

The voltage of 210

p>

is within the normal range

The higher the generator load, the lower the voltage will be.

Generally, 210-230 is the normal range. Suggestion: Change to a larger generator

Or replace the water pump with a smaller one

Or combine a pneumatic switch with larger current to replace the generator circuit breaker itself even

This should solve the problem

The water should be dry, do not remove the lid to dry it. Even though it can be used temporarily, it will cause more serious problems over time, so if you don't save time, it will enterwill lead to higher maintenance costs in the future.

A static sealing mechanism is provided between the connection port and the connection surface, between the fixing bolt and the bolt hole, and between the motor shaft and the mounting hole. TREE.

The outer part of the engine is made of anti-corrosion material or anti-corrosion coating. Since any cracks or channels that may exist inside and outside the sealed motor are blocked by the sealing mechanism, reliable sealing can be achieved. Even if the motor is watered for a long time, water will not enter the motor and cause a short circuit. At the same time, it also has certain explosion-proof performance.

Extended information:

CollectBrushless DC motors using position sensors electromagnetics comprise components of cElectromagnetic adapters (such as coupling transformers, proximity switches, LC resonant circuits, etc.) installed on the entire stator. When the position of the permanent magnet rotor changes, the electromagnetic effect will cause the electromagnetic. sensor to change. A high-frequency modulated signal is generated (the amplitude of which changes with rotor position).

An electric motor is a rotating electrical machine that converts electrical energy into mechanical energy. It mainly includes an electromagnetic winding or a distributed stator winding to generate a magnetic field and an armature or a rotating rotor. Under the action of the rotating magnetic field of the stator winding, a current flows through the squirrel cage aluminum frame of the armature and is affected by the magnetic field to make it rotate. Some types of these machines can be used as electric motors or generators.
