1. The carbon brush is installed in the brush holder to ensure free up-and-down movement. The gap between the carbon brush and the inner wall of the brush holder is between 0.1 and 0.3 mm, which prevents wobbling due to a gap.

2. The carbon brushes are suitable for a variety of motors, generators, and shafts. They offer improved switching performance.

3. The carbon brush will move up and down in the carbon brush holder. Please remove any excess material if it does not function properly.

If the carbon brush is worn to a certain extent, it needs to be replaced. 4. If the carbon brush's conductor wire is covered with an insulating tube, it must be installed in an insulated carbon brush holder. 5. The surface orientation must be correct; otherwise, if the contact area is too small, electricity production will be low or will not produce any electricity.
