The role of the carbon brush holder is to apply pressure to the carbon brush sliding in contact with the commutator or slip ring surface through a spring, so that it can conduct current stably between the stator and the rotor. The brush holder and the carbon brush are very important parts for the motor.
When keeping the carbon brush stable, checking or replacing the carbon brush, it is easy to load and unload the carbon brush in the brush box, adjust the exposed part of the carbon brush under the brush holder (the gap between the lower edge of the brush holder and the commutator or slip ring surface) to prevent wearing out the commutator or slip ring, the change of the pressure of the carbon brush, the direction of pressure and the position of pressure on the carbon brush wear should be small, and the structure should be firm.
Carbon brush holder is mainly made of bronze castings, aluminum castings and other synthetic materials. The brush holder itself is required to have good mechanical strength, processing performance, corrosion resistance, heat dissipation and electrical conductivity.
Morteng, as the leading manufacturer of generator brush holder, has accumulated a lot of experience of brush holder. We have many type of standard brush holder, at the same time, we can collect the request from our customer, to customized and design different holder according to their real application.
No matter how good the characteristics of the carbon brush, if the brush holder is not suitable, the carbon brush can not only give full play to its excellent characteristics, and will bring great impact on the performance and life of the motor itself.
If any inquiry, please feel free to send to Morteng, our engineering team will fully support you to find a suitable solution!
