Uses of carbon brushes in power tools

The main function of the brush is to make the electrical connection between the components and the moving parts in an electric motor. Namely the stationary part (stator) and the rotating part (roto).

For drilling machines, grinders, saws, polishing machines, vacuum cleaners, … the carbon brush plays an important role, because most of these hand tools use an electric transmission mechanism to strong rotational force.

In addition, carbon brushes also have applications such as:

• Use with car or motorcycle motors.
• Household appliances such as: vacuum cleaner, dryer, blender.
• Generator engine application.
