What are the main aspects of carbon brushes? Track certain areas that touch the carbon brushes to find the correct state of the carbon brushes. Rings with high peripheral speeds often have spiral grooves to increase the stability of the brush. The chamfered edges will not wear out with carbon brushes. The same is true for the commutator. Correct the abnormal phenomenon on the surface to prevent damage to the brush and increase its service life. Solve vibration problems caused by poor alignment, poor operation or improper balance. These conditions prevent good contact between the commutator and the carbon brushes. If you ignore these problems, problems such as vibration can cause serious damage to the brushes and brush holders.

There may be dust grooves on the surface of the brush. These grooves further increase their state and performance. Use a brush of length to adapt it to a constant pressure. Carbon brushes need proper support for a long time. The brush also needs to have a specific gap to prevent wedging. The electrician defines the gaps for different brush sizes. This prevents problems such as hammering or wedging. Correctly align the brush holder and arrange regular cleaning during inspection to prevent damage to the brush.

Carbon is the material of these brushes. Carbon has electrical, physical and mechanical properties suitable for protecting motors from damage.
