Abstract
The lifetime of an electric-motor depends mainly on the lifetime of its electric-brush. At high-rotating speed the electro-mechanic wear of the electric-brush increases steeply and the knowledge on the dynamics of the electric-brush becomes even more important. The aim of this project is to enhance the electric-brush knowledge to allow substantial increase of rotating speed of suction units at reduced electro-mechanical wear. This aim could be achieved by enhancing the recent and very promising research on physically correct modelling of multibody contacts to the field of electro-mechanic contact. It is believed that this would be a suitable framework for modelling the dynamics of electro-mechanic problems with several degrees of freedom including transitions like: stick, stick-slip, adhesion, detachment and impact. A very important and also challenging role in this project will play the measuring of needed electro-mechanic characteristics and also experimental verification of the dynamical model. The progress on electric-brush dynamics would improve the competitiveness of the Slovene electro-industry.
