Abstract
An assembly for a rotor of an electrically excited electric machine includes a rotor shaft, a slip ring, and two bearing points. The rotor shaft is fixedly connectable to a rotor core of the rotor to thereby conjointly rotate. The slip ring module has at least one slip ring configured to energize rotor windings of the rotor. The two bearing points are arranged at axial ends of the rotor shaft with one annular bearing seat of one bearing of the rotor. One of the bearing points is of two-part configuration. The two part bearing points with the part bearing seats are connected in a positively locking and non-positive manner with configuration of the bearing point with the annular bearing seat.
