Description:
There are starter motor carbon brush, generator carbon brush, motorcycle carbon brush that can be called automobile carbon brush. It has a proper chamfer, appropriate specifications, standard structures. There should be no loosing, getting off, damaged parts, dislodged angles or edges or clamps for the good quality one.
Automobile carbon brush (motorcycle carbon brush) is widely used to A/C blower motor, alternator, accessory motor, slip and ring motor, motorcycle starter, automotive starter, A/C blower motor, accessory motor, B/V application, automotive alternator and so on.

Main Feature:
We can offer automobile carbon brush with proper quality.
(1) Our carbon brush can be long duration and not damaging the commutation or the collecting ring.
(2) It is good commutation and collecting capability that can successfully limit the sparks within the capacity and minimize the energy consumption.
(3) The products that we offer feature in no over heat, low noise and no wearing out when the automobile's brush is in operation (the motorcycle's brush).
(4) It is able to form a film of even, moderate and stable oxygen quickly on the surface of the commutation or the collecting ring when it is in operation.

Starter Motor Carbon Brush
There are series motors for starters motors. Different power has different rate voltages. Normally it is like follows:

gasoline car 360-2000 ml displacement	12V/0.4~1.2kw
small diesel vehicles ?2000-3000ml displacement	12V/1.5~3kw
large diesel cars	24V/3.7~11kw

The brushes are required to be high torque and instantaneous overload durability when the motor is starting, for this moments the current is large, the contact voltage drop should be paid attention to and the spring pressure should be increased.

Generally speaking, the carbon brush with a low contact voltage will have a large degree of wear. Therefore, the materials of the carbon brush should be determined according to the torque and the longevity of the motor. .while, the brush's weight decreases when the motors rotating speed increase. The brush's longevity is calculated on the assumption that it is started for 20,000 to 50.000 times. If the motor rotate 10 times per day, the totaling life can be 6 years.

This kind of carbon brush need more mental material in its ingredients, and can be more vulnerable to the low temperature and low moisture compared with the other type. To manufacture this brush, we should add some special ingredients to reduce the wear between the carbon brush and the commutation.

Generator Carbon Brush
The DC shunt generators can improve the output of the power/weight rate. Motors that have difficulties in commutation should use power graphite brush. While those with extreme difficulties use natural graphite that is of high resistance. And using soft graphite can lower the noise made by the carbon brush.
Accessory of Motor Carbon Brush
Those heating equipment, like water heaters, scrubbers have been widely installed in automobiles. As well as the air-conditioning, air-conditioners, window lifters and seat adjustment devices all need to use carbon brush.
