What are generator brushes, and what are they for?

Brushes generator - this is an integral part of the system of supply and removal of electric current. Despite their small size, they are of great importance to the machine. After all, if the brushes do not function - the generator in the car will no longer generate tension. Accordingly, all electronic mechanisms will not function properly.

What is noteworthy, the generator brushes are used not only in cars with gasoline and diesel ICE, but also in electric engines of trolleybuses and load-lifting machines. In addition, this element is indispensable when using welding machines and many other tools working on electrical energy.

At the moment, all the brushes of the generator are made of graphite, and regardless of whether they are used on the machine or on a car. Now there is a huge number of models and varieties of these details. The coal brushes of the EG-4 model are widely used. They are no different from their counterparts. However, there are also such generator brushes, which are characterized by their special composition with a special impregnation, which does not allow the mechanism to fail before the specified time. Usually they are used for high-speed electric motors. Often these motors are equipped with generators of the EG 61 series. It is also worth noting that not all parts can be fitted to a specific generator. The car starter and all electronic devices will not work if there are foreign brushes under the hood. Therefore, when choosing, always refer to the manufacturer's recommendations. Having learned the exact brand and model of the device, you can easily select the necessary part.

If the purchase of special problems for motorists does not arise, then with the installation quite the opposite. And that the generator brushes worked with maximum benefit, you should closely monitor the sequence of your work. In general, the replacement process is not very complicated. It consists of the following stages:

• Dismantle the generator from the fasteners.
• Remove the special plug from the brush holder.
• Unscrewing the screw securing the last part (here it is desirable to use a small screwdriver, in order to speed up the replacement process).
• Withdrawal of brush holder.
• Installation of parts.
• Assemblage of spare parts in the reverse order.

Also one of the most frequently asked questions is the replacement of brushes. To answer this question, you need to look at the detail externally and evaluate its degree of wear. To do this, take into account the distance to which the generator's brushes protrude from the holder. If this value does not exceed a mark of 5 millimeters, then the part is subject to urgent replacement.

Proceeding from this, it can be concluded that the brush generator, although a primitive detail, but without its presence is no longer possible to make a move on the car. You can start a car, but in this case, all the load from electronic systems will be put on the battery. And she, as a rule, keeps ignition without brushes only a few minutes. Therefore, it is advisable to keep several sets of such devices in reserve so that in the middle of the road you do not have to call the tow truck.
