Divided into graphite carbon brushes and copper added carbon brushes (half copper and all copper)

8mm*8mm*32mm

10mm*10mm*32mm

etc.

1. If the outgoing line of the carbon brush is covered with an insulated pipe, it should be installed in the insulated carbon brush holder; The outgoing wire is bare copper wire and should be installed in the grounding carbon brush holder.

When installing the carbon brush onto the carbon brush holder, attention should be paid to the direction of the curved surface. Reverse installation may cause the contact surface to be too small, resulting in weak or no power generation.

3. The carbon brush should be able to rise and fall freely inside the carbon brush holder. If there is any jamming, the excess part should be ground off.

4. The carbon brush spring should be pressed in the center of the carbon brush to prevent uneven force and eccentric wear.

5. The contact area between the carbon brush and the commutator should not be less than 3/4 of the entire contact surface, and the carbon brush should not have oil stains.
