Micro Motor Carbon Brushes

Micro-electric motor brush life expectancy shorter than the large-scale electrical machinery, but the use of household appliances is shorter, therefore, a group generally can use the brush a few years in the life of electrical brush need to be replaced during the examples of many . 
Material from the brush of a general can select a low friction coefficient and contact voltage drop of larger graphite electric brush, resin binder for the high resistance of natural graphite brush can be used for the poor motor. In addition, more abrasive strong carbon-graphite brush is mainly used mica sudden ultra-small motor.
