Household Appliances

Special Requirements for Material and Design

Carbon brushes and brush holder assemblies used in household appliances demand special requirements of both material and design.

Our product range includes carbon brushes, brush holders and modules for electro-motors in washing machines, vacuum cleaners, household appliances, hair- and hand-dryers.

Today's motors are designed to be smaller and lighter, while simultaneously increasing rotational speeds.

The Business Unit Small Motor Technology reacted to this trend with material development many years ago. In this context special value is placed on the continuous improvement of the commutation behaviour as well as a steady increase of efficiency.

The Schunk Advantage - Possibility to Eliminate Radio Interference Suppression Coils

Generally, Schunk carbon brushes ensure a low level of radio interference. In many cases, motor design engineers can achieve required radio frequency interference levels entirely without suppression coils (chokes). Resulting in cost reduction as well as space savings.

Schunk Special Development: Sandwich Carbon Brush

Schunk is the world market leader for the manufacture of carbon brushes and holders / modules for washing machine motors. In most application cases, Schunk’s special development, the sandwich carbon brush, is employed: a carbon brush consisting of two halves glued together and separated by an insulating middle layer, a design which decisively reduces leakage current.

For perfect commutation, we have also developed a matching brush holder and module for these carbon brushes. They provide optimal commutation for both Alternating Current (AC) and Direct Current (DC) power supply.

Carbon Brushes and Modules for High-Speed Vacuum Cleaners

We have been involved in the development and production of high-speed vacuum turbines for years. In this field, we offer solutions for all voltage ranges between 100 and 240 volts, as well as for all power ranges, including the most modern generation of motors with power output of up to 2,000 watts and more. The efficiency of the turbines can be measurably increased through the use of our special materials.
