MiDruStat


Project description

Electrically operated micromotors with a diameter of only a few millimetres are already being used in a wide range of applications such as automation technology, robotics or medical technology. However, the conventional winding of stator coils is reaching its production limits with increasing miniaturization. This leads to high reject rates and reduced efficiencies. Within the MiDruStat project, an innovative manufacturing approach is to be investigated by printing the stator system using conductive inks on ferrite foils.

The chair FAPS is investigating the following aspects among others:

  • Analysis of the material properties of different ferrite foils and their suitability for printing with conductive inks and pastes
  • Development of a piezo jet or aerosol jet manufacturing process to produce the printed coils
  • Development of processes for winding, sintering and contacting the printed stator systems
