What is the normal output power of the generator of a general 5 seat car?

1: Under normal circumstances, the power generation of the generator is about 14V, because after starting the car, there is a generator to supply the whole car and charge the battery, that is to say, the battery is basically useless when the car is started.

Now the car has various speed valve, air conditioning speed, steering speed, power consumption speed, shift speed, etc., you turn on the air conditioner, headlights and gas pedal in the case of power generation only, that is indeed low, under normal circumstances, should be able to reach about 15V.

2: The integral generator is generally replaced as a whole, because his regulator is integrated, and the built-in regulator cannot manually adjust the power generation.

It can be charged and meet the normal operation of the car, but the headlights, starter and CD are the most power-consuming, and if the headlights and CD work at the same time, they cannot be satisfied.

4: No, the normal regulator sets the regulation voltage to about 14V, if there is a problem with the regulator, and the engine does not speed up when the headlights and air conditioning are turned off, the voltage will not go up.

The voltage at idle speed should be about 14V, and when the speed increases, it will be slightly increased to about 15V, which will not be very high.

It can not only be seen from the output voltage, but also involves the battery capacity and current.

The battery can be tested with a discharge test table.

To test whether the generator voltage and current are suitable, there is a simple way: normal driving for about half an hour, touch the side of the battery with your hand to test the temperature, very hot (more than 100 degrees) = power generation is too high, you can also get started (70-80 degrees) = power generation is suitable, micro temperature (within 50 degrees) = power generation is too low.

The temperature of running at high speed is appropriately raised.

Car generatorsThe power is around 1900 watts.

The car generator is the main power source of the car, and its function is to supply power to all the electrical equipment on the car when the engine is running normally, and at the same time charge the battery. The conversion of the high and low speed power supply circuits of the generator in operation is automatic, and no electromechanical control devices are added.

The working principle of the car generator, in the low speed range, due to the low speed of the generator, three phases.

The series output of the winding increases the output voltage of the generator, which greatly improves the low-speed charging performance of the generator.

In the high-speed range, with the increase of the generator speed, the inductive reactance of the series connected three-phase winding.

As it increases, the internal voltage drop increases, and the armature reaction intensifies, causing the output voltage to drop. At this time, the original three-phase winding generates an induced current due to a small internal voltage drop.

Relatively large, ensuring power output at high speeds.

Around 1900w.

The car generator is the main power source of the car, and its function is to supply all electrical devices when the engine is running normally (above idle).

Backup (except starter) power supply, while charging the battery. On the basis of the windings of the ordinary alternator three-phase set, increase.

The number of winding turns and the terminal head are drawn out, and a set of three-phase bridge rectifiers is added. At low speed, it is output in series by the original winding and the additional winding.

At higher speeds, only the original three-phase winding is output.

The normal power of the automobile generator is as follows: 1. Power: The rated speed of the generator is 6000R, the rated voltage is 12V or 24V, and the rated speed of the heat output current is the rated current, and the general consumption is about 1900W; 2. The automobile generator is the main power supply of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally (above idling), and charge the battery at the same time; 3. On the basis of the ordinary alternator three-phase group, increase the number of winding turns, lead out the terminal, and add a set of three-phase bridge rectifier.

Low speeds are output by the original winding and windings in series, while at higher speeds, only the original three-phase windings are output.

The engine power of small cars is generally 350 watts to 500 watts, large ones are 500 watts to 1000 watts, and heavy cars are generally more than 1000 watts.

There are many types of lead-acid batteries, where type Q is defined as a starter battery. It is characterized by a very small capacity but a high maximum rate, the standard is generally 6-qa-55-650, the concept refers to the dry-charged lead-acid battery composed of two groups of cells, and the maximum discharge coulomb is 650 standard. The capacity concept is [12V-55Ah], which is converted into kWh (degree) only degrees; And this is still the best capacity in theory, and it is good to reach 80% or 90% under actual working conditions.

There are very few power-consuming devices when the car is turned off, only the anti-theft system sensor and the remote key sensor, and if the engine is turned off, the navigation and speakers may be used; The normal "standby" of locking the car can generally support about 20 days without losing power, but after adding other power-consuming equipment, it will cause the capacity and voltage to decrease in about 1 hour and cannot be started. However, these devices are not very power-hungry, and if they are powered by batteries at start-up, the vehicle will lose power in a few minutes.

Out-of-the-box. The power consumption of a gasoline-powered car is quite large, such as fuel pumps, cooling water pumps, spark plugs, and electronic devices. Among them, the spark plug needs to boost the 12V electric voltage to more than 10,000 volts through the ignition coil, and the ignition work at an ultra-high frequency can ensure the normal operation of the internal combustion engine. So coupled with air conditioning fans, internal and external lamp groups and other equipment, how long can the battery that relies on about half a kilowatt-hour of electricity last for normal power supply?

Generator rated speed 6000r;

Rated voltage 12V or 24V;

The hot state output current at the rated speed is the rated current; This parameter is set according to the design requirements of different models. Such as (75a; 80a, etc.);

How the integral alternator works.

When the external circuit energizes the excitation winding through the brush, a magnetic field is generated, which magnetizes the claw pole into the n pole and the S pole. When the rotor rotates, the magnetic flux changes alternately in the stator winding, and according to the principle of electromagnetic induction, an alternating induced electromotive force is generated in the three-phase winding of the stator. This is how the alternator generates electricity.

The synchronous generator rotor of the DC excitation is dragged by the prime mover (i.e., the engine) and rotates at a speed n (rpm), and the three-phase stator induces the alternating current potential around the resistance. If the stator winding is connected to the electrical load, the motor has an alternating current output, and the alternating current is converted into direct current through the rectifier bridge inside the generator and output from the output terminal.

The alternator is divided into two parts: stator winding and rotor winding, the three-phase stator winding is distributed on the shell according to the electric angle of 120 degrees different from each other, and the rotor winding is composed of two pole claws. When the rotor windings are connected to direct current, they are excited, and the two pole claws form the n pole and the s pole. The magnetic field lines start from the n-pole, enter the stator core through the air gap, and return to the adjacent s-pole.

Once the rotor rotates, the rotor windings will cut the magnetic field lines, generating a sinusoidal electromotive force in the stator windings at an electric angle of 120 degrees, that is, three-phase alternating current, which is then converted into a direct current output through a rectifier element composed of diodes.

When the switch is closed, the battery first supplies the current. The circuit is:

Battery Positive Charge Indicator Regulator Contact Excitation Winding Resist Tie Negative Pole of Battery. At this time, the charging indicator light will be on due to the current passing through it.

However, after the engine starts, as the speed of the generator increases, the terminal voltage of the generator also increases. When the output voltage of the generator is equal to the battery voltage, the potential of the "B" and "D" ends of the generator is equal, and at this time, the charging indicator is extinguished due to the zero potential difference between the two ends. Indicates that the generator is working normally, and the excitation current is supplied by the generator itself.

The three-phase AC electromotive force generated by the three-phase winding in the generator is rectified by the diode, and the direct current is output, which supplies power to the load and charges the battery.

Generally a few amps, twenty or thirty amps when just starting. However, the output current of the generator is large, plus the load consumes electricity.

Usually it's 12v or 24v300 watts, and it's to say more than a thousand watts

The output voltage of the automobile generator is generally about to.

Methods of detecting generators:

1. Prepare a universal watch.

2. Adjust the gear to DC voltage and select the 20V position.

3. Open the car cover and find the positive and negative poles of the battery.

4. Then the red pen is connected to the positive pole, and the black pen is connected to the negative pole.

5. Start the engine, and then you can see the numbers displayed by the multimeter, such as is.

Power: generator rated speed 6000r; Rated voltage 12V or 24V; The hot state output current at the rated speed is the rated current; Generally, it consumes about 1900w.

The car generator is the main power source of the car, and its function is to supply power to all electrical equipment (except the starter) when the engine is running normally (above idle), and at the same time charge the battery.

On the basis of the three-phase winding of the ordinary alternator, the number of winding turns is increased and the terminal is drawn out, and a set of three-phase bridge rectifier is added. At low speeds, it is output in series by the original winding and additional winding, and at higher speeds, it is only output by the original three-phase winding.

The working principle of the integral alternator: when the external circuit energizes the excitation winding through the brush, a magnetic field is generated, so that the claw pole is magnetized into the N pole and the S pole. When the rotor rotates, the magnetic flux changes alternately in the stator winding, and according to the principle of electromagnetic induction, it can be seen that the alternating induced electric turbulence potential is generated in the three-phase winding of the stator.

This is how the alternator generates electricity.

According to the different box lengths of the vehicle, the appropriate generator set can be installed, which can be installed with 50 kW-500 kW. Clan raids such asIsuzuThe generator car can be equipped with 30-120 kW generator set.

The carriage equipped with the generator set is required to be silencing and irritability, and it is also equipped with auxiliary fuel tanks, cable reels, lighting and other equipment. It can be used for power generation, equipment maintenance, conference support, field operations and other functions.

The work of the mobile emergency power supply vehicle has the following characteristics

1. It is used as an emergency, and the use time of its continuous operation will not be too long, under normal circumstances, it only needs to work for a few hours, and the maximum time will not exceed 12 hours.

2. It is to be used as a backup of Youshi, the emergency generator set of the vehicle is generally in a shutdown waiting for the emergency start, only when the main power supply is lost in the event of a failure, the emergency generator set will run and start the power to the emergency power load.
