Symptoms of a bad alternator regulator: The battery cannot fully maintain electrical power, leading to a gradual decrease in battery power and even the inability to start the car. The standard battery voltage is 12V, and it can reach 14V when the battery is fully charged (the engine working state). Virtual lights on cars, screens, etc. when the battery is discharged (when the generator is not producing electricity). turn on, they don't
What are the symptoms of a broken generator regulator
Symptoms of a broken generator regulator: The battery cannot fully maintain the power supply, resulting in a loss of power to the battery. gradually decrease, or even fail Start the car. The standard battery voltage is 12V, and it can reach 14V when the battery is fullloaded (the operating state of the engine). Virtual lights on cars, screens, etc. when the battery is discharged (when the generator is not producing electricity). Are bright, they are not working properly and indicate intermittent operation.
As its name suggests, the regulator regulates the power generated by the generator. Since the speed of the car engine is uncertain and the generator is driven by the engine, in order to stabilize the electricity generated by the generator at about 14.0V, the internal magnetic field current of the generator needs to be adjusted . When the speed is low, the regulation current is large; when the speed is high, the regulating current is small, so that the generator can output constant voltage.
At present, alternators are widely used in automobiles. The following points should be considered whentheir use:
1. Frequently clean the scale and dust from the outside of the generator. to keep it clean and in good condition;
3. The tension of the transmission belt must be appropriate. If it is too loose, it will slip easily and result in insufficient power production; if it is too tight, it will easily damage the belt and generator bearings
4. When installing the battery, do not install it; incorrectly. Usually install the positive wire first, do not install the ground wire, otherwise the diode will be easily burned out.
5. When using an integrated circuit regulator, the ignition switch should be turned off immediately when the engine is not running
6. Never use the “scrape” method of testing whether; electricity is generated;
7. When the generator cannot generate electricity, it should be eliminated in time, otherwise it will causes more serious defects.
What should you pay attention to when maintaining and inspecting the generator?
Points to note when servicing and inspecting generators: Make sure there are no problems with this part of the connection. On the other hand, it is necessary to carefully check whether the insulation between the turns of the rotating coil is intact. Good insulation is a prerequisite for normal generator operation.
Reduce the effects of magnetic flux. The generator set core end plate is equipped with a conductive shield, which can function as a magnetic baffle. And since most core end plates are stepped, this shape can increase local magnetic resistance and achieve better heat dissipation.
At the same time, in singleThe division of sheets in the element can increase the resistance and extend the path of eddy currents, rthus reducing eddy current losses. Additionally, when designing the core ends, overall considerations must be made not only to reduce eddy current losses as much as possible, but also to maintain appropriate thermal and magnetic characteristics. Laminations must be made from low-loss materials at the right time and must be made with uniform pressure.
Demagnetize the field coil by demagnetizing the component. Routine maintenance and repair of generator rotors should be strengthened. If the rotor is grounded, the fault must be eliminated in time. Workers should always check the exciter, pad insulation to ground, oil pipe insulation, etc. Detailed instructions are given during routine maintenance of the generator set; in addition, the motor components to be demagnetized can be placeded in the excitation coil, which can increase the excitation current, and when the demagnetization component is lifted, the current can be reduced. When the current reaches zero, demagnetization is complete. What are the symptoms of a broken generator regulator? What should you pay attention to when repairing and inspecting the generator @2019
Common faults of automobile generators: 1. Do not charge unless the transmission belt is too loose and. sliding without loading, it generally needs to be checked. The generator itself is not producing electricity or the regulator is faulty, or the charging circuit is shorted. 2. The charging current is too low, which is usually caused by insufficient voltage of the generator itself, poor technical condition of the regulator and increased resistance in the charging circuit.
3. The charging current is too highso much and the car's ammeter pointer deviates to the maximum charging current position; If you are driving at night and the engine speed is high, the instrument lighting and indicators will be particularly bright. 4. The charging current is unstable. When the engine is running above idle speed, the ammeter pointer swings left and right, indicating intermittent charging (sometimes charging and sometimes not charging). Generally, the voltage across the generator is unstable. 5. The generator is not producing electricity. The main reasons why the generator does not produce electricity are: short circuit or open circuit of the rectifier diode; field winding short circuit or three-phase stator winding phase short circuit or rotor slip; heavily oxidized and dirty bushing, carbon The brush holder is damaged or the carbon brush is stuck inthe brush holder. .
Automotive generators can be divided into DC generators and AC generators Since AC generators are superior to DC generators in many aspects, DC generators have been eliminated at the 'actual hour. alternators, so how do alternators work? Automotive generators also rely on the principle of electromagnetic induction. When the external circuit feeds the excitation winding through the brush to generate a magnetic field, and when the rotor rotates, the magnetic flux alternately changes in the stator winding. According to the principle of electromagnetic induction, an alternating induced electromotive force is generated in all three. - stator phase winding. If the stator winding is connected to an electrical load, the motor will produce alternating current. AC current will be converted to DC via the rectifier bridge insideof the generator and output from the output terminal. This is how a car's alternator produces electricity.
