Carbon brush material, also called electric brush material, can be used for generators or electric motors; electrical machinery; carbon
resin, copper, antimony, impregnated, mechanical, seal, bearings, carbon, graphite, material, impregnation, manufacturer, factory, China.
There are mainly 5types of carbon brush materials, Main types: Metal graphite material; Silver graphite material; pure graphite material; resin graphite material and electric graphite material. Here we will introduce another type of carbon brush material: Resin graphite material. We will show the data sheet of resin graphite material and its applications.
Resin graphite material: application:
Highspeed series motors; Electric tools, household applicances; d.c. or a.c. commutator machines…
