The motor (rotor + stator) is the heart of a power tool, and the carbon brush takes on the task of powering the rotor. In the case of rotational speed of more than 10,000 revolutions per minute, carbon brush and the rotor commutator constantly high-speed friction, the quality of carbon brushes have a severe test. Poor carbon brush often have the following performance:
Material is too soft: lead to frequent replacement of carbon brushes, increase the cost of use.
Excellent material: leading to serious rotor wear and tear, shorter life expectancy, outweigh the benefits.
Poor conductivity: affect the performance of electric tools, power greatly reduced.
Poor material, poor welding: the use of wire for a period of time off, carbon brush smash.
Therefore, we strongly suggest that you use the original carbon brush, absolutely value for money! !
