VAZ 2110, generator: voltage, price, installation and repair. How to check the VAZ 2110 generator?

On cars VAZ 2110 the generator is executed on quite standard scheme. No unnecessary elements, all nodes and parts are time-tested and reliable. Such designs are used by all automakers. The reason for this - high reliability of the unit. Simplicity and ease of maintenance are the main criteria for an automotive generator. The simpler it is, the easier it is to repair it and the more reliable it will turn out to be. Consider the main components that make up the tens generator. This will help you understand the principle of its operation, and also facilitate the performance of repairs.

Rotor of the generator VAZ 2110

The rotor is that part of any electric machine that rotates. In alternating or direct-current motors, it is driven by an electromotive force. But not everything is so simple. For example, asynchronous motors have a rotor with short-circuited coils of a thick wire. But the generator VAZ 2110, whose price is about 3000 rubles, has a slightly different design of the rotor.

It uses a metal core made from a special grade of steel. It winds the winding. It is called the excitation winding. It allows us to get the strongest electromagnetic field, which later, when moving, induces EMF in the stator winding. The latter should be discussed separately, since its design is very interesting. At the VAZ 2110 the generator has a design that differs significantly from the one used in the early models. True, the changes are mostly in the drive area.

Stator generator tens

Of course, there is a base - a set of steel plates. Inside, the copper wire is laid. In fact, the winding of the stator in the car generator is exactly the same as in the asynchronous motor. Only three identical windings are located on the entire surface of the stator. They connect to the "star" - their beginning is connected to one point. The AC voltage is removed from the ends of each of the coils.

Of course, it would be possible to use not one but one winding instead of three. Only the effect of this would be small. If you carried out the repair of the VAZ 2110 generator, you know what happens when one of the entire stator windings fails. The ripple of the output voltage increases, the operation of the generator becomes incorrect. Reducing the ripple of the output voltage is exactly the problem solved by the design consisting of three windings included in the star.

Rectifier block

This is an assembly of six semiconductors - elements that pass current in only one direction. It is with their help that the voltage of the VAZ 2110 generator is converted from variable to constant. Consequently, at the output you will get stable 12 volts, which are necessary for charging the battery and supplying the vehicle's on-board network. But a stable voltage is possible only under the condition that a constant magnetic field is created in the excitation winding.

Only under this condition will the output voltage be stable. Otherwise, it will fluctuate from the minimum value (about 10 V) to the maximum (about 30 V). Stabilization of the output voltage is handled by a unit called a relay-controller. If earlier used exclusively mechanical devices, then in modern cars, including VAZ 2110, electronic devices are used. Installation of the VAZ 2110 generator can be done before the brush assembly with the voltage regulator is mounted .

Covers, impeller and bearings

In the front and back of the generator there are aluminum covers. And it should be noted that the rear serves for the most part to close the rotor and brush assembly. But the front performs a more significant role - it mounts an impeller and a pulley for the drive belt. On the new dozens, the belt is multicore, on the first models only wedge-shaped ones were used.

Similar belts were worn on models 2108-21099. In both covers there are bearings. They serve to center the rotor relative to the generator housing. The impeller is made of thin metal, to it one requirement is to provide reliable cooling of the device case. And for this you do not need to make great efforts. That's all the external elements that the VAZ 2110 generator has, the price of which is around 3000 rubles.

Checking the efficiency of the generator

It is not difficult to perform a test if there is at least a simple tester. To understand whether the generator is working on the VAZ 2110, it is necessary to conduct its diagnostics. So, if the lamp in the dashboard burns, then obviously there is some kind of malfunction. Look first at the relay-regulator, assess the condition of the brushes. It is possible that they are torn off or completely worn out. In this case, you can correct the deficiencies only by completely replacing the node.

Start the engine, turn on the dipped beam. In this mode, a good battery charge should be provided. Measure voltage at its terminals. If it is below 12.5 V, then look for a breakdown. It is possible that the belt has a weak tension. If higher than 13.8 V, check the voltage regulator. Most likely, it failed, does not correct the output parameters. That's all the ways that describe how to test the VAZ 2110 generator without dismantling it from the car.

Removing and replacing drive belt

To do this, you will need a new belt. Removing the old is quite simple - you just need to unscrew the nut on the bracket. After that, you need to push the generator housing to the engine - the closer, the better. Consequently, the belt tension will decrease, it will be easier to remove it from the pulleys. Pay attention to the condition of the pulleys. If they are damaged, have excessive wear, then it is desirable to replace them too.

A new belt is put on the crankshaft pulley . Then carefully install it on the pulley of the generator. Try to combine the streams as precisely as possible so that slippage does not occur. Now it remains only to move the generator to the VAZ 2110 to conduct the belt tension. Pay attention to the fact that excessive tension is the rapid wear of the bearing of the generator and the belt itself. And insufficient - this is a high probability that there will not be enough charge. And the belt in this case will simply slip.

Conclusion

It is very important to keep the generator clean. If there is no full-scale crankcase protection, then install the shield. It will reduce the amount of water and dirt that can get to the generator. And not only for him - without shields, all the engine room will get very dirty very quickly. In addition, timely and high-quality repair of the VAZ 2110 generator can increase its service life. The components required for maintenance have a cost several times lower than the entire unit.
