What is the reason why the rotor of a car generator does not generate electricity without magnetism

The first case is when the starter works, but the engine does not. This is complicated by the fact that it can be caused by one of several failures. It is rare for two or more failures to occur at the same time, but it cannot be said absolutely.

1) First of all, it may be a circuit or electronic fault. The phenomenon that occurs is very sudden and without warning. The faults of the circuit are:

The fuse is blown out, the high-voltage coil is broken, the low-voltage circuit is broken, the center ignition wire is off, the distributor head is leaking, and the spark plug is damaged. Electronic failure mainly refers to the loss of function of the computer control board.

Oil pump failure, oil circuit failure, oil filter blockage, carburetor failure, nozzle damage, etc. Sometimes it happens that the fuel tank is empty and the owner doesn't know about it. Add a few liters of petrol and you'll be able to solve all the problems.

3) Finally, it can also be a mechanical failure. Common mechanical failures are: time band (chain) breakage, cylinder leakage without pressure, etc.

The second scenario is when even the starter does not work or works barely. At this time, the first thing that needs to be checked is the battery or battery.

There are many ways to check, but it's best if you have a voltmeter on hand. Connect the positive and negative poles of the battery, and then twist the key to ignite. At the moment of powering on, if the voltage indication suddenly drops below 8 volts, there must be a problem with the battery.

It doesn't hurt to have a voltmeter, you can replace it with a small 12-volt bulb and a small section of power cord. The same is true for the method, if the bulb suddenly becomes significantly darker, it is also an indication of battery aging. In many cases, the battery has failed, but the headlights can still be lit.

This is not surprising. Only at the moment of ignition can the performance of the battery be truly tested. Because this is when it has the most load.

Another simple way is to look at the outer wall of the battery with the naked eye, and if you find that it has expanded and deformed, it means that a new battery is absolutely needed. In addition to the battery, the reason why the starter does not work can be a damaged ignition switch, a damaged ignition relay, or a damaged starter itself.

Also, check the ground line and fuse.

1.The generator did not operate in accordance with the specified technical conditions.

2.The three-phase load current of the generator is unbalanced.

3.The air duct is blocked by dust and poor ventilation, which makes it difficult for the generator to dissipate heat.

4.The inlet air temperature is too high or the inlet water temperature is too high.

5.Too much or too little grease is applied to the bearing.

Summary. If there is no magnetism in the rotation of the power supply line itself, then you need to check whether the power supply line is normal, and if the power supply line rotates normally and there is no magnetism, then you need to check whether there is a problem with the coil and carbon brush.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

If there is no magnetism in the rotation of the power supply line itself, then you need to check whether the power supply line is normal, and if the power supply line rotates normally and there is no magnetism, then you need to check whether there is a problem with the coil and carbon brush.

The battery died, it started with the power, then the wire was removed and the engine stopped again.

This is that the generator is not generating electricity, and you need to see if there is a problem with the line.

Then there is the fact that the generator is not magnetic.

Is the generator broken?

Check the power supply of the generator line first.

If there is no problem, there is a problem with the generator.

Is it a battery. The power supply is the line, the fuse.

Where is the fuse, the positive and negative poles of the battery are short-circuited, will the generator have no magnetic force, are you the owner or the repairman? This fuse must be in the fuse box, right? You'll need to use a test light to test it.

I am the owner of the car, called to repair the car, he used screws to put the generator there is no magnetism, said to change the generator, nothing checked, because I drove dozens of kilometers a few days ago, the generator has no problem, came back and stopped for more than a week without driving, and then the battery is out of power, the electricity is on fire, the wire is removed, the engine is off, then you check the plug of the generator first, see if there is power supply, if there is no power supply, check the fuse, If the power supply is normal, it is a generator problem.

If I can help you, please give me a thumbs up Thank you!

Car generators have a magnetic field but do not generate electricity Reason:

1. There are at least three open circuits in the generator rectifier diode, positive or negative electrode tube;

2. The stator coil is burned out at least two phases or more;

3. The armature connector has poor contact or output break;

4. The line between the generator and the battery is broken.

1. Appearance inspection: carefully inspect whether the generator, regulator and ignition switch are loose, whether the generator is firmly fixed, and whether the V-belt is loose or has oil stains and slips.

2. Check the regulator: connect the two wires together (that is, the ignition switch to the regulator, and the regulator to the generator magnetic field binding post), and start the vehicle If it generates electricity, it means that the fault is in the regulator (platinum contact ablation, weak contact spring tension or resistance burnout, etc.).

3. Check the generator: remove the generator magnetic field terminal wire, turn on the ignition switch, and scrape the removed wire on the magnetic field binding post, if there is a blue and white spark, it means that the circuit in the magnetic field is good. If there is no spark, it means that the carbon brush is not in good contact or the magnetic field coil is broken.

Fourth, use a screwdriver at the back end of the generator (201 bearing cover) to test whether there is magnetic suction. A normal generator should have obvious suction, if there is no suction or weak suction, it means that the excitation circuit is faulty.

Summary. Hello dear, glad to answer for you! The failure of the new generator of the car is due to the following reasons:

1. The internal damage of the generator may be due to the damage of the magnet inside the generator or the damage of the magnetic core, resulting in insufficient magnetic field, so that the magnetic force cannot be generated. 2. The battery voltage is insufficient, the generator needs enough voltage to generate magnetic force, if the voltage is insufficient, the generator cannot generate magnetic force. 3. Improper wiring of the generator, if the wiring of the generator is improper, it will also cause the generator to fail to generate magnetic force.

4. The magnet of the generator is not magnetized, and the magnet of the generator must be magnetized to produce magnetic force. 5. The magnetic core of the generator is damaged, and the damage of the magnetic core of the generator will also cause the generator to be unable to produce magnetic force. Hope the above can help you solve the problem.

Hello dear, glad to answer for you! The lack of magnetism in the new automobile generator is caused by the following reasons: 1. The internal damage of the generator may be due to the damage of the magnet inside the generator or the damage of the magnetic core, resulting in insufficient magnetic field, so that the magnetic force cannot be generated.

2. The battery voltage is insufficient, the generator needs enough voltage to generate magnetic force, if the voltage is insufficient, the generator will not be able to generate magnetic force. 3. Improper wiring of the generator, if the wiring of the generator is improper, it will also cause the generator to fail to generate magnetic force. 4. The magnet of the generator is not magnetized, and the magnet of the generator must be magnetized to produce magnetic force.

The new generator doesn't generate electricity within 20 minutes.

The generator does not generate electricity every 20 minutes, which is due to the failure of the control system of the generator's pure core, or due to the open circuit of the generator's power line or connecting line, or the failure of the generator's control circuit, or due to the burning of the generator's motor windings. In addition, there may be a program error in the generator's control system, or the generator's control system may have a corrupted control signal, etc. Therefore, it is recommended that you check in time to find out the cause of the failure in time, and take measures to solve the problem in time before the change.

Summary. Hello, I'm helping you sort out the answer to your question, please wait a while What happens when a car generator has a magnetic field but doesn't generate electricity?

Hello, I am helping you sort out the answer to your question, please wait a while If the generator has a magnetic field, it can only mean that there is no problem with the force magnetism of the generator, but if the generator wants to send out an incoming call, the rotor and stator inside the generator need to work, and the rectifier of the generator also needs to be normal to ensure that the generator can generate electricity. So now you can basically be sure that the generator itself is broken, and you can replace it with another one.

Summary. Pro, the generator is the main power source of the automobile electrical system, it is in normal operation, all the electrical equipment except the starter is powered, and the battery is charged to supplement the electric energy consumed by the battery in use. The generators used in automobiles include DC generators and alternators.

The DC generator uses a mechanical commutator to rectify, and the alternator uses a silicon diode to rectify, so it is also called a silicon rectifier generator.

Hello dear, glad to answer for you! The original seepage judgment of automobile generator does not rotate is as follows: 1. The generator is overheated, the neutral line of the generator has abnormal voltage to the ground, the power of the generator is insufficient, and the stator winding insulation breakdown and short circuit; 2. The stator core is relaxed, the iron chips are short-circuited, the generator loses remanence, and cannot generate electricity when starting; 3. After the generator starts, the voltage cannot rise, and the car battery is damaged.

Poor shouting. Pro, the generator is the main power source of the automobile electrical system, it is in normal operation, except for the power supply to all the electrical equipment except the motor of the Ant Bureau, and charge the battery to supplement the battery in the use of the nuclear consumption of the stuffy electric energy. The generators used in automobiles include DC generators and alternators. The DC generator uses a mechanical commutator to rectify, and the alternator uses a silicon diode to rectify, so it is also called a silicon rectifier generator.

Mine is a 12v generator, after the engine starts, what is the reason why the generator won't turn.

Pro, it is the generator overheating, the generator neutral wire has abnormal voltage to the ground, the generator power is insufficient, and the stator winding insulation breakdown and short circuit;

Hello, dear! If the generator does not have a magnetic field without the ear bark, then it cannot generate electricity. The method of processing is to re-establish the magnetic field, which can be achieved in the following ways:

1.Rotate the rotor of the motor with a battery or other magnet with a strong magnetic field for a period of time to establish a magnetic field. 2.

Check that the magnetic poles of the generator are magnetized, if not, the magnetic poles need to be remagnetized. 3.Inspect the generator's coils for damage or poor contact, and if so, need to be repaired or replaced.

Explanation: The working principle of a generator is based on a magnetic field, which generates an electric current by rotating the magnetic field. If the generator does not have a magnetic field, then it cannot generate electric current and cannot generate electricity.

Therefore, re-establishing the magnetic field is a necessary step to deal with the absence of a magnetic field in the generator. Extension: A generator is a device that converts mechanical energy into electrical energy.

Its working principle is based on Faraday's law of electromagnetic induction, which states that when a conductor moves in a magnetic field, an electromotive force is generated. There are many types of generators, including DC generators, alternators, synchronous generators, etc. Generators are widely used in various fields such as industrial production, transportation, and agricultural production.

It is necessary to pay attention to maintenance and repair during use to ensure its normal operation.
