Specification:
Product: Motor Carbon Brush
If the motor does not run at full load or does not run at all, it is time to replace the brush. When the brush rubs with the motor armature, small sparks are normal, but too many sparks may mean that a new brush is needed.
If a new carbon brush is replaced, and it does not take a few minutes or hours to find that the carbon brush has been worn or half-worn, it means that your rotor has caught fire. Please replace the rotor in time. If you do not replace the rotor, it is useless to replace any more carbon brushes (if the rotor catches fire, it means that the carbon brush is already burning).
