Abstract
In an assembly for electrically exciting the rotor of an electrical machine, the wear of the sliding contacts is reduced in operating conditions with low current density in that an AC current is injected. The additional injection of the AC current is superimposed upon the DC current. The rotor poles function as an open circuit with respect to the AC current through a co-rotating capacitor.
