One of our greatest strengths is the development and production of small and micro carbon brushes, i.e. small, ready pressed precision parts for small and ultra-small motors. Our micro carbon brushes are used in mains and battery powered mini-motors, e.g.
- ultra-small motors for the office area
- high quality motors for toys
- mini-motors for medical equipment
- audio-video appliances
Particularly high demands are placed on precision motors with very small dimensions – namely that they run easily and noiselessly but with a relatively high output.
The physical properties of our materials are defined above all by parameters such as
- transitional voltage
- coefficient of friction
- specific electrical resistance
- Rockwell hardness
- bending strength
- gross density
- metal content
- permissible peripheral speed
- and continuous current density
and designed accordingly. The ‘secret’ is to find the right mix of these properties so that the high demands on the precision motors can be met. With our many years of experience, we can help you to find the optimum mix for your needs.
