使用碳刷注意事项

1. 碳刷的引出线套有绝缘管的，应装在绝缘碳刷架内；引出线是裸铜线的，应装在搭铁碳刷架内。

2. 碳刷装入碳刷架上时，应注意曲面方向，装反会接触面过小，发电弱或不发电。

3. 碳刷在碳刷架内应能自由起落，如有发卡现象，应磨去多余部分。

4. 碳刷弹簧应压在碳刷正中，防止受力不均发生偏磨。

5. 碳刷与整流子的接触面积，应不小于全部接触面的3/4，碳刷不得有油污。

Precautions for using carbon brushes

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.
