Abstract
A rotor arrangement () for an electric machine of a vehicle. The rotor arrangement () comprises a rotor lamination stack () and the rotor arrangement further comprises a rotor support (). The rotor support () carries the rotor lamination stack (), which is arranged on the radially outer side () of the rotor support (). A retaining element is arranged on the outer side () of the rotor support at the end on the rotor lamination stack (). The retaining element is a one-piece, closed retaining ring () with an axial ring width (SR) and with at least a first ring diameter (R). The first ring diameter (R) is smaller than or equal to the rotor support diameter (TR), so that the rotor laminate stack () is secured axially in a rotationally fixed manner. The invention also relates to two production methods.
