CHECKING CARBON BRUSH

Brush Maintenance Essentials (Effective Length)

The brush is the area which touches the slip ring, and its surface must be kept smooth.

If it is not smooth then carbon and other substances will adhere between the brush and slip ring.

This must be buffed with sandpaper or the like because it is hazardous.

The usable length of the brush is 5~11mm, so if the brush is 5mm long or less replace it with a new one.

ENGLISH

This is done because if the length of the brush gets any shorter, its contact pressure with the slip ring will decrease, resulting in a drop in generator efficiency and the output voltage.

Check the brush every 500 hours to confirm its length.

In addition, check the brush length if the generator malfunctions, such as when it is not generating power or its voltage is low.

Length when new

10~11mm
