Brush and commutator motor (or ring collector) contact, as
the sliding contact conduction current and improve the
commutation, brush quality affects directly the using
performance of motor. It is an important component of motor.
Carbon brush processing factory has the international
advanced automatic production line. Mainly the production of
motor brush, brush a larger share of the railway, the
application of our products all over the count
D**4 type brush I plant the first developed for railway
traction motor, Dongfeng series, which is characterized by
good reversing performance, good wear resistance. With the
train speed, our company has developed TMC, TMD and other
products. New products TMD, it is characterized by high
resistance coefficient, fire suppression capability is
strong, good wear resistance, the test run results show that,
the product can run three minor term, TMD is currently the
best brush products of high speed locomotive.
