Which generator is suitable for the VAZ 2110

If the generator is seriously damaged, it does not have to be repaired, but completely replaced. Parts necessary for repair may be missing, or the breakdown may not be repairable at all. Meanwhile, the on-board voltage and the quality of battery charging depend on the good operation of the power unit. It's a shame when, despite a good motor, electrical equipment does not work properly.

And if we are talking about VAZ cars, then sometimes a replacement is in demand due to the lack of power of standard devices. Modern automakers offer many additional devices that increase the level of comfort when traveling, but they also consume a large amount of electricity, and old devices cannot cope, so they have to be replaced with more powerful ones.

Many people are interested: which generator to buy if they have a VAZ? Here you need to consider them separately by model, so before you go shopping, read the recommendations of specialists and compare them with your wishes and capabilities.

Principle of operation

The principle of operation is this: you turn the key in the lock, and current flows to the excitation wire. The magnetic field that the armature creates penetrates the stator windings, at the terminals of which voltage appears. When the armature reaches a sufficiently high rotation speed, which is provided by the pulley and belt drive, the so-called self-excitation mode occurs.

The rectifier unit converts alternating current into direct current. The voltage regulator starts working when the crankshaft speed changes (accordingly, the armature rotates faster or slower) and regulates the time for which the field wire is turned on. Sometimes a generator malfunction may occur due to a blown fuse in the circuit.

Functions performed

So, what is a generator for? First of all, in order to provide all VAZ 2110 equipment that runs on electricity with energy. Perhaps someone thinks that this is the battery's task. Not really, because the battery is needed to maintain functionality when the engine is not running (it starts the engine, supports the alarm, music system while parked, etc.).

But when the engine has already started, with the help of the battery, the generator comes into play. During the trip, it is he who supports the operation of all electronics, air conditioning, audio (or even video systems), and everything else that you have added to your VAZ 2110.

Another equally important function of the generator is charging the battery. This also happens when the engine is running. And if it weren’t for this device, the battery would not be able to cope with its tasks, and it would have to be charged all the time.

Considering that today on the VAZ 2110, in addition to the standard layout, many additional energy consumers are installed, it happens that the generator voltage is not enough. In this case, it makes sense to install a 120 amp generator.

Specifications

Most often, the VAZ 2110 is equipped with a Katek generator, usually designated by the numbers 5102.3771, but it can also be 94.3701. Both generators have a power of 80 amperes, and the output voltage is about 14V. But recently Katek has been releasing a new type of generator, also suitable for the VAZ 2110.

It produces a current of up to 120 amperes, and is more suitable for the high energy loads of a modern car. By installing a 120-amp generator, you can ensure simultaneous uninterrupted operation of almost all electricity consumers.

Types of generators

There are different types of generators for VAZ cars depending on their design. The most common generators are compact in size - 94.3701 and others.

Owners of Russian-made cars install brushless inductor-type generators. For example, devices modification 955.3701. Such generators differ from traditional equipment by the presence of permanent magnets on the rotor and field windings on the stator. Thanks to this, the design of the generator set does not contain slip rings and an alkaline unit, which is one of the most vulnerable and poorly protected.

Device components

If the generator device is considered in terms of size, then there are compact and traditional ones. They also differ in their design features.

drive pulley;
excitation wire;
bracket;
anchor device.

They can be fastened with one bolt, or with several, and other “little things”. However, any generator has a general structure.

The rotor (or armature) is the rotating part of the generator. The armature is designed to create a magnetic field using an excitation winding located on the shaft. The excitation wire is powered by slip rings located on the same shaft. The following are also located here: the excitation winding wire, the fan impellers (one or two), the drive pulley and the bearing assembly;
The stator is the stationary part of the generator, consisting of three windings (three-phase), which create alternating current. These windings can be connected to each other by the so-called “star” or “delta”;
The housing is most often made of lightweight non-magnetic aluminum alloy; it consists of two covers, secured with a bolt. The front cover is located in the same place as the drive pulley; the back cover is on the side where the slip rings are. Each bolt that connects the back and front covers is tightened. In the future, to disassemble the generator on a VAZ 2110, it is enough to remove the bolt mounts;
Mounting the generator on a VAZ 2110. There is an upper mounting bracket that uses 2 bolts. The lower mounting bracket most often has one bolt, but there may be two, in which case minor modifications may be necessary. The bolt can be anything, the main thing is that the size is suitable, sometimes a sleeve is required for this. It is better not to redo the bracket itself. The bracket securely holds the generator, which has many responsibilities. And yet, we should not forget that the bracket, like the bolt, can break, so you need to monitor its condition;
The structure of the brush assembly consists of two graphite brushes, springs that press them, and a brush holder;
In modern Katek generators, the voltage wire and brush holder are located together in a non-separable unit. Therefore, if the voltage regulator fails, the entire assembly must be replaced. Structurally, this regulator can have a hybrid device - when radio elements with electronic devices are in the same circuit. But an integral is when the regulator is made in thin-film microelectronics technology. Many believe that the integral regulator copes better with its mission - controlling the duration and frequency of current pulses. The regulator changes the voltage used to charge the battery. At higher temperatures, less voltage goes to the battery. Although, in principle, it is not so important whether the integral is responsible for this regulation, or the hybrid;
A rectifier unit with six diodes is responsible for converting the alternating current generated by the armature and stator into direct current, directly used by all on-board equipment. It also serves to charge the battery;
The device is driven by a belt drive. It provides a significant increase in the speed at which the crankshaft rotates. In this case, the V-belt wears out faster if the pulley has a small diameter. If the driven pulley is small, it is better suited to a serpentine drive, which is more often used in modern generators.

Here, in brief, is the basic structure of generators, regardless of whether they produce 80 or 120 amperes.

Design Features

The stator core has a cylindrical shape. A three-phase winding is wound on it according to a star circuit, the ends of which are brought out to the rectifier block. The stator is protected from above by a housing consisting of two covers fastened together with four bolts. There is an anchor inside it. It is mounted on two ball bearings. Their purpose is to ensure uniform rotation of the shaft.

At the rear of the generator there is a rectifier module consisting of six diodes, as well as a voltage regulator with a brush holder and brushes. For protection purposes, these elements are covered with a steel casing.

What to choose?

In terms of popularity and reliability, the first places are occupied by manufacturers Bosch (Bosch), Denso (Denso) and Delphi (Delphi). But you should know that Katek (KZATE) (made by us) are also quite reliable and do a good job of their duties on the VAZ 2110, creating the required voltage. Maybe somewhere they lose against Bosch, but compared to the Chinese they are at their best.

VAZ generators of the tenth family:

So it’s difficult to say for sure which generator is right for you; the best one is the one that provides the necessary power to operate electrical appliances and charge the battery. If we take the advantages that Katek clearly has, then this is sufficient reliability, and also - what is important - the availability of inexpensive spare parts for sale: you can always buy at least a fuse, a pulley, an armature, a voltage regulator, an excitation wire, etc.

Step-by-step instructions for installing and assembling the tens generator

Guide to dismantling the VAZ 2110 generator:

The tensioner nut is unscrewed.
The generator unit moves slightly back towards the vehicle interior. The drive belt is removed from the pulleys. Then the electrical power circuits of the device are turned off. One block with wires is fixed with a nut and a stud; they must be unscrewed and disconnected. The second connector is attached using a regular block, which is detached.
After this, the lower nut securing the assembly is unscrewed. This action is performed from under the bottom of the car. To complete the task, it is necessary to dismantle the power unit protection, if any.
The screw that needs to be removed is usually fastened tightly. When unscrewing it, you need to treat the part with WD-40 if it is stuck and cannot be removed. You can use a hammer to remove the retainer.
Then, from the reverse side, this element is removed completely.
At the final stage, the nut that secures the tensioning device is completely unscrewed. The generator unit is moved to the side, this will allow it to be completely dismantled.

Generators for VAZ 2106 and 2107

The generator on the VAZ 2106-2107 costs the same as on the VAZ 2101 - G221. If you install additional external current consumers that operate constantly, this will lead to undercharging and insufficient current will be supplied from the relay regulator. These additional devices include:

powerful audio systems;
fog lights;
TV;
preheater;
additional heater;
fridge.

Any similar device will lead to greater power consumption and, consequently, to premature battery discharge, even when the engine is running at high speeds. Standard devices for 2106 were developed a long time ago and are not designed for modern energy-consuming add-ons.

In this case, it is recommended to replace the standard generator with a more powerful unit.

What to install?

G 222

If you need to increase the current power, then, when deciding which generator is better to install on the VAZ 2106 or 2107, instead of the standard one, take the G 222, which was installed on the VAZ 2105, Nivakh. It would seem that it itself is no better than the standard one on the “six”, but you can take an upgraded version that will be more powerful. Unlike the 221, this unit is designed with a built-in regulator relay, assembled into one unit with brushes. The G 221 gives an output of 42 A, and the 222nd - 50 A. Increasing the cross-section on the rotor winding increases the power, although the design is completely similar to the G 221. However, to install it on the 2106 you will need minor modifications. The easiest way is to install brushes from G 221. They fit perfectly in place of the relay. This modification is quite feasible even for car enthusiasts who do not have the skill.

It can be installed on a VAZ 2106 G222 with a standard regulator, but then it is necessary to change the connection diagram of the electrical machine.

On 2107 everything is installed without problems.

Check the voltage at medium engine speeds at the battery terminals, if it is 14 V at 2500 rpm, then everything is fine. You can drive with a more powerful unit by connecting additional options.

2. Generator 2108

This installation has greater efficiency, delivering a current of 55 A. It is installed on both 2106 and 2107.

The mount is identical to the standard ones, there are no problems during installation. Just remember to remove the battery terminal. You'll have to tinker with the connection to 2106. There are 4 wires going to the standard device. On the “eight” - three, since the voltage relay is built-in. To get a good result, insulate the black wire, connect the rest according to the standard system. The light bulb - the discharge indicator will light up when the generator is running, and will go out if there is no charging.

It is useful to make some more minor modifications. Instead of the old relay, install a regular power one. Then the light comes on only when the engine starts and at low speeds.

On 2107 you only need to add a power relay.

2107-3701010

An even more powerful installation is from the VAZ 2107i, producing 80 A, which can also be installed on the VAZ 2106–2107. With such equipment it is possible to install any electrical systems. For VAZ 2106 only 2107-3701010 is suitable; You can use any generator of this series for the carburetor “seven”.

When installing this equipment on 2106, it is better to modify it: replace the relay regulator with a similar one from G 222.

Some useful tips to extend the life of your generator

To ensure that your “ten” generator serves for a long time and does not present unpleasant surprises, use the following tips.

At least once a month, check the condition of the device’s drive belt and its tension. If it is damaged, immediately take measures to replace it.
Pay attention to the sound of the generator. If you hear a hum characteristic of failed bearings, replace them yourself, or contact a service center for this.
Do not connect electrical appliances to the vehicle's on-board network that consume a current greater than the current generated by the generator.
If the warning light on the instrument panel is constantly on, indicating that the battery is not charging, check the voltage regulator. If it fails, replace it.
Do not expose the generator to water. It can cause a short circuit.

Lada Priora - generator replacement

The Priora requires a powerful generator; the car has a lot of electronics and a weak installation cannot cope with it.

A generator labeled 5102.3771 is recommended for the Priora, providing a power of 80 A; on luxury versions with even more electronics, a 115 A device is installed. Then which generator is better to install on the Priora?

Car owners recommend a unit produced by KZATEtm Samara plant under number 9402.3701-14, producing 115 A.

There is no need to modify it during installation, you just need to find the connector, because there are differences from the standard one. You can use a plug from a VAZ-2108 from the limit switch for turning on the reversing lights, which costs only 20 rubles.

Next, you will have to make a little modification when connecting to the “B+” power terminal in order to fit it to the desired size.

The cost, of course, of domestic units is higher than that of Chinese or Bulgarian ones, sold for 2200 and 3000, respectively. For Russian ones they ask for about 4000. But if you need repairs with Russian-made components, you can easily find spare parts.

Interchangeability of autogenerators

Interchangeability of generators for Lada cars is achieved if the following requirements are met:

Most Russian-made automobile generators have a 2-leg mount. These fasteners are found on both covers. For equipment of foreign brands, installation is carried out using 1 paw, the fasteners are located on the front cover.

In order to correctly install and securely fasten a foreign generator in a car from AvtoVAZ, it is necessary to replace the bracket.

Which generator is better to put on a VAZ 2110

VAZ 2110 factories install KATEK generators with a current of 80 A. The service life is 140,000 km, which is approximately 10 years of vehicle operation. Answering the question of which generator is better to install on the VAZ 2110, experts recommend products from Russian manufacturers.

What to consider when choosing

Russian manufacturer or foreign? Of course, first of all, Russian manufacturers are preferable. If only because it is easier to find spare parts in the event of a minor breakdown. If you purchase a generator for a VAZ 2010 from a not so popular company, it may be difficult to find spare parts, and they will not cost you so much.

Current strength. Factory models for VAZ 2010 - 3771 or 94.3701 - are designed for 80 A, this current is enough, even if there are additional devices that consume it. More powerful ones - 120 A - are installed in the presence of powerful acoustics, no harm is done to the battery, and you will provide all energy consumers with uninterrupted current.
It is better to purchase a generator if there is a warranty on it. There may well be a defective product, and the warranty will provide the opportunity to replace it with a new one.

Generator Manufacturers

It is best for 2010 to purchase a standard generator from KATEK or KZATEtm Samara plant, and about 50% of owners do just that, according to statistics. They are reliable, cope perfectly with their functions, creating the necessary tension.

Among the foreign-made generators, we can recommend Bosch, Delphi and Denso, which are also reliable and popular.

Generators for VAZ 2114

The generator initially built into the 2114 is low-power, and if it also breaks down and you decide to purchase a new one, the question arises: which generator is better to install on the VAZ 2114? It is important here that the unit is more powerful, but there is no need to change the fastenings.

The most successful replacement option for a VAZ 2014 is a generator from a Priora or Kalina with air conditioning. This installation has a power of 115 A, which is 35 A more than the characteristics of the units.

Installing these generators for 2014 usually does not cause problems, however, it will be necessary to replace the pulley, but it only costs about a hundred rubles and is not difficult to find.

The Eldix brand generator also has a power of 115 A and works well. The disadvantage is that it is almost impossible to find spare parts, and even if there is a minor breakdown, you will have to replace the entire generator instead of repairing it.

Please note that a lack of charging voltage can occur simply due to oxidation of the battery terminals; keep an eye on them by cleaning them regularly.

Generators for VAZ 2115

VAZ 2115, created on the basis of the “nine”, adopted the main components and assemblies from it. Accordingly, there are also many problems with equipment. If the car has a carburetor engine, it can be equipped with a 55 A generator 37.3701, which differs from the above in the mounting method. However, this voltage is not enough for the constant use of modern audio systems, fog lights and other energy-consuming options. Which generator is better to install on a VAZ 2115 - car owners definitely recommend installing it with a power of at least 80 A. Now on the VAZ 2115, as well as on 2113-2114, three-phase 94.3701 with an output of 80 A are installed.

For more power, you can install a 90 A Priorov generator KZATE 9402.3701 in 2015, which is suitable for the mounting and pulley. A reliable unit will provide you with the necessary energy for any number of energy-consuming devices.

Summarizing the above, it can be noted that when buying a generator at a VAZ to replace a broken one or to increase power, it is better to choose Russian models, since they are most suitable in design and you will not have to carry out expensive modifications. In addition, you will always find the necessary

The best prices and conditions for the purchase of new cars

My adventures began three years ago, being in a semi-fainting state, I came to the electricians for service with the problem of the battery being discharged - after poking around for about 10 minutes under the hood, the electrician rendered a verdict: Gena is dead - install a new one, because... the way was far, I went to a nearby store of the rank of PBOYUL (or there were already individual entrepreneurs then, I don’t remember) and purchased a generator of the KZATE brand (see Fig. 1) for 80Ah (a standard generator for the 10th eight-valve Zhiguli family).

Device Description

First, let's look at the generator design. Regardless of which unit we are talking about - old or new model, it includes many different elements. A more detailed description is given in the figure below. For the VAZ 2110, the Katek device is initially installed from the factory.

Principle of operation

As for the operating principle of Katek or any other device, the following:

When you turn the key in the ignition switch, voltage begins to flow to the excitation wire.
The armature comes into operation and when it reaches a high rotation speed, provided by the belt drive and pulley, a self-excitation mode is formed.
Next, the alternating voltage is converted to direct voltage through a rectifier unit.
The 3-level 2110 comes into operation after the crankshaft speed changes. The regulator adjusts the time at three levels at which the excitation wire is activated.

Removal and Installation Guide

Dismantling and installing a new device at home is not so difficult.

The connection diagram for the generator and the connection of all components is as follows:

First you need to turn off the power to the car's on-board network; to do this, open the hood and disconnect the battery.
Next, locate the generator assembly in the engine compartment and disconnect the excitation cable from it.
Using a 10mm wrench, you need to unscrew the nut that secures the two wires to the “B+” terminal. Once the nut is unscrewed, the wires can be disconnected.
Next, you need to remove the strap. If its condition is deplorable, then the belt needs to be changed to prevent it from breaking at the most inopportune moment. The strap should be replaced if it shows signs of damage, such as cracks or other signs of wear. Unscrew the mechanism adjusting screw, after which you can unscrew the fixing nut.
After these steps, you can remove the tension bar of the assembly.
Using a 13 mm wrench, you can unscrew the nut that secures the lower fastening of the unit.
Remove the screw and remove the device from the car. Further installation of the new unit is carried out in the reverse order.

Price issue

If you need to buy a new generator unit, then you need to take into account that its cost varies not only depending on the manufacturer, but also on the technical characteristics. The more powerful the generator, the more expensive it will cost.

The main electrical device that provides power to the VAZ 2110 2111 2112 car while the engine is running is the generator.

Maintenance of the VAZ 2110 2111 2112 generator and the applicability of the generator from Lada Priora.

A guarantee of uninterrupted and reliable power supply to the car is the correct and timely maintenance of the generator. (replacement and adjustment of the generator belt, brushes, preventive cleaning of dirt and dust). The VAZ 2110 generator has similar electrical output characteristics and connections as the Lada Priora generator, or rather, the Priora borrowed the generator from the VAZ 2110 - 2112.

Voltage regulator

The regulator performs the function of a kind of stabilizer. Thanks to it, the voltage of the vehicle’s on-board network is the same, regardless of the number of revolutions of the running engine.

Essentially, a regulator is a relay that closes and opens a circuit. It happens like this. The voltage dropped below the required value, or rose above the norm - the relay disconnected the generator from the network. The voltage has reached the desired range - the regulator connected the device.

There are no electromechanical elements in the VAZ-2110 generator relay. It is built on semiconductors. In addition, its design also includes a brush holder with brushes. It is almost impossible to repair the regulator on your own. It's easier to replace it with a new one.

Checking the functionality of the relay takes no more than five minutes. Yes, and there is no need to disassemble anything here. The diagnostic procedure is as follows.

We start the engine and warm it up to operating temperature.
Turn on the low beam headlights and the heater fan.
Using a tester turned on in voltmeter mode, we measure the voltage at the battery terminals.

The voltage should not go beyond 13.2 - 14.7 V. If it is higher or lower, the relay is faulty.

A regulator is considered faulty if its brushes are damaged or excessively worn. The minimum length of brushes is 5 mm.
