The correct installation method for carbon brushes

The correct installation method for carbon brushes usually includes the following steps:

Power outage and disassembly. Before starting the installation, ensure that the device is powered off and then remove the old carbon brush. Use appropriate tools (such as a screwdriver or wrench) to remove the carbon brush cover on the motor and expose the position of the carbon brush.

Clean the contact surface. Gently wipe the contact surface and groove of the carbon brush with a cleaning cloth to ensure there is no dust or debris.

Install a new carbon brush. Choose a new carbon brush with the same size, material, and model as the original one, and gently insert the new carbon brush into the carbon brush slot to ensure good contact with the surface of the motor rotor.

Adjust the length and angle of the carbon brush. Adjust the length and angle of the carbon brush according to the equipment requirements to ensure good contact with the collector ring.

Fix the carbon brush. Use fixing screws or clips to secure the new carbon brush in the appropriate position, ensuring its stability and reliability.

Inspection and testing. After installation, open the device for testing to check if the carbon brush is properly installed and functioning properly.

It should be noted that during the installation process, the power supply should be disconnected to avoid electric shock accidents. At the same time, pay attention to the carbon brushes

Manufacturing method of carbon brush box

The so-called carbon brush box (also known as carbon brush holder) is a batch product that provides about 40 million pieces of multi-layer carbon brushes annually. These types of carbon brushes are mainly used in the electric motors of washing machines. The corresponding carbon brush holder is commonly made of brass plate because it can achieve good conductivity. The brass plate also has the advantage of being machinable. If multi-layer carbon brushes are assembled into corresponding carbon brush holders made of conductive materials, large axial and radial clearances need to be selected to avoid short-circuit currents, where the axial clearance is greater than the radial clearance. Here, the axial and radial directions involve the commutator supported by multiple layers of carbon brushes. Due to the fact that the electric motor on the washing machine can work both right-handed and left-handed, the carbon brushes flip and pass through the edges of the brushes. This will emit noise. When in the flipped position, the carbon bars of the multi-layer carbon brush come into contact with the carbon brush grip wire, causing a short circuit current, resulting in high coil temperature and commutator temperature.

In order to use the corresponding carbon brush box or brush holder in places with high atmospheric temperatures, it is necessary to use electroplated coated brass plates, such as nickel plated brass plates, to prevent the occurrence of copper green.
