carbron brush for micro motor with Children's toys, sports models, precision instruments :
Brushes for micro-motors require small sparks, long life, and low noise. Therefore, the brushes must have good electrical conductivity, wear resistance and commutation; various shapes of tiny electric caps (contacts) are automatically formed by a single pressing New technology production.
Details :
The product materials mainly include electrochemical graphite, resin bonding, pitch bonding, grease-impregnated graphite, and metal (including copper and silver) graphite.
Carbon brush advantage :
- Low friction coefficient at 100m/sec
- Low contact drop
- Low losses/Higher load capabilities/
