Automobil carbon brush

•  starter carbon brush:

The series e*cited motor is for Starter motor. The rated voltage and rated power is as following: 12 volt/0.4-1.2 kilowatt is for the gasoline automobile petrol car (air capacity 360-1200 milliliter). 12 volt/1.5-3 kilowatt is for minitype diesel car (air capacity 2000-3000 milliliter). 24 volt/1.5-3 kilowatt is for umbrella diesel car.

It needs the carbon brushes to be with high torque characteristic when the car is in low speed and instantaneous over loading resistance to wear. We have to be careful about the brush contact drop because the starting current is very strong. And at the same time the spring pressure have to be improved accordingly. General speaking, the carbon brush wear quickly the touch voltage is low. So, we can apply the right carbon brush grade according to the torque. The electric machine's rotation rate is gradually increased as the carbon brushes' weight lightened when the electric machine are running. The international standard for the carbon brushes' life time is about 20000-25000 times starting (ten times starting per day, which can be used about 6 years) .

Compared with the other kinds of carbon brushes, The starter carbon brushes can be affected easily by low temperature and low humidity because the starter carbon brushes contain high component copper. To reduce the abrasion between the carbon brush and commutator, we generally add some plumbum and stannum and other special element.

•  Generator machine carbon brushes

Shuntwound direct current generator also can improve the rate of output power/weight. We choose the most appropriate carbon brush material grade is very important, such as, the electro graphite carbon brushes is for commutation hard motors; and the high resistance natural graphite carbon brushes is for those commutation very hard motors; and we also can use the soft grade carbon brushes to resolve the motor noise problems.

•  Au*iliary motor carbon brushes

Heating installation, wiper and washer have been widely used in the car. Besides, the air condition, car window lifting equipment and seat adjust equipment also need to use the carbon brushes.

BOYO AUTOMOBIL CARBON BRUSHES have been FORMED A COMPLETE PRODUCTION NETWORK for the car parts OEM company. And we also e*ported a lot to the European countries and American countries.
