Carbon brush material, also called electric brush material, can be used for generators or electric motors; electrical machinery; carbon brushes.
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 one type of carbon brush material: Electric graphite material. We will show the data sheet of electric graphite material.
Electric graphite material.
application:
Highspeed turbo-generators and d.c. machines of small /medium size; Small high speed series motors; Traction motors and main generators for locomotives high speed excites for turbo-generators, rolling mill motors, and main generators, e.c. commutator motors and other d.c. motors with some difficulties of communtation…
