Rotor arrangement and method for mounting the rotor arrangement of a separately excited electric machine of a vehicle

Abstract

A rotor arrangement with a hollow-shafted rotor shaft (1) for a separately excited electric machine (2) is proposed, wherein an axially insertable inductive transmission device (4) can be arranged inside the rotor shaft (1) and at least one rotor winding can be arranged on the outer circumference of the rotor shaft (1), wherein a contact is provided for electrically connecting the inductive transmission device (4) and the rotor winding, wherein the contact is a contacting element (5, 5A) fixed in a radial shaft passage of the rotor shaft (1), and wherein the contacting element (5, 5A) has a first axially oriented contact area (6) at one end facing the transmission device (8) for electrical connection with the transmission device (8) and a second contact area (7) at one end facing the outer circumference of the rotor shaft (1) for electrical connection with the rotor winding.Furthermore, a separately excited electric machine (2) with a rotor arrangement and a vehicle (3) with at least one separately excited electric machine (2) are proposed.
