Using of brush holders in electric motors

Brush holders are important and integral part of commutator motors. These elements are mounted in electric motors, generators and other engines which use brush systems to transfer electrical contact to rotating parts.

Functions of brush holders

The most common problem with Opel Easytronic, Ford Durashift EST and Honda I-Shift robotic gears occurs when the Latin letter “F” lights up on the dashboard, the box is in emergency mode and the car doesn't start. Connect a diagnostic scanner and read the error codes of the gearbox control module. In our case, there is one error: P1607-00 - malfunction of the actuator clutch. 

To access the block and download the pumping of the battery brake system, remove it.

The pump is located at the bottom of the coupling, so first of all you have to drain the oil from couplings. We loosen the filler plug, but do not unscrew it completely, because it is difficult to catch the oil from the drain. Turn off the drain plug, substitute a clean container (if you want to use the oil again) and merge. As soon as the pressure decreases, you can unscrew jellied for air intake, merged. Disconnect the pump connector from the control unit, it is the first from the cardan coupling.

       Opel Easytronic is an automatic transmission that is designed for Opel cars, its analogues are boxes such as: Ford Durashift EST ASM, designed for Ford cars, and i-Shift Honda Civic 5D, designed for Honda Civic cars. This transmission has been designed to make driving easier and reduce driver fatigue. One of the features of the Opel Easytronic is the ability to shift gears in both automatic and semi-automatic modes. In automatic mode, the system itself determines the required gear, depending on the vehicle speed and driving mode. In semi-automatic mode, the driver can independently select the desired gear using the gear lever on the steering column. 

A copper-graphite, or carbon brush, is a technically necessary component of an electric motor. A real user cannot touch or see these brushes, as they are hidden in the motors of the devices, which will be discussed later, but in this article we will try to reveal the principle of operation and the benefits of copper-graphite brushes.

Usually we associate the word "brush" with a toothbrush, a shoe brush, or a brush for cleaning clothes, but not with a small graphite product that makes a motor working. This name was fixed in the middle of the 19th century, when the first electric motors and generators used brushes made of bonded copper wires (copper-braided brushes). Subsequent inventions replaced them with graphite (carbon) blocks, so the concept of "brush" has survived and people continue to use it.

        A commutator motor is a type of motor that consists of a fixed part and a moving part. The fixed part is called a stator, and the movable part is called a rotor. commutator motors can be DC, AC, and universal, all three types are widely distributed on the market and are found in household electrical appliances, construction and industrial equipment, as well as in various vehicle components, such as: motors for stoves and air conditioners, motors for parking heaters and clutch actuators, four-wheel drive pumps, ABS systems, etc.
