motor brushes

Carbon brush material, can be used for generators or electric motors.

There are mainly 5 types of carbon brush materials:

1)Electric graphite material

Application:

High speed 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

Resin graphite material

Application:

High speed series motors; Electric tools, household applicances; d.c. or a.c. commutator machines…

1-2). Pure graphite

Application: Steel Slip rings for high speed steam turbo-generators; Especially suitable for slip rings of large turbo-generators

2). Metal graphite material.

Application: d.c. generators with low voltage and slip rings of a.c. asynchronous motors; Slip rings of synchonorous generators, wind driven generators; Automobile starters and exciting slip rings of synchronous machines

2-2). Silver graphite material

Application:

Generators for car window scraper, warm air motors, motorcycles; Slip contacts for conducting current and transmit signal; Contacts for signal devices; a.c. miniature electrical machines.
