Rotor carrier for rotor arrangement of electric machine and method for producing positioning means in rotor carrier

Abstract

The invention relates to a rotor carrier (1) for a rotor arrangement (20) of an electric machine of an electric or hybrid vehicle, having:-a flange connection part (2) for connecting to a flange means (22) of a shaft (21) of the rotor arrangement (20), and-a receiving section (3) for a laminated core (23),-wherein the flange connection part (2) is connected to the flange means (22) of the shaft (21) of the rotor arrangement (20), the receiving part (3) has a laminated core holder (4) for a non-rotatable arrangement of the laminated core (23) and an axial stop (5) for limiting a movement of the laminated core (23) in the axial direction (A), and wherein the receiving part (3) has at least one positioning means (6) for positioning the laminated core (23) in the axial direction (A), the laminated core holder (4) has at least one positioning means (6) for the relative alignment of the laminated core (23) on the laminated core holder (4),-wherein the at least one positioning means (6) has two grooves (7, 8) which are designed to have different widths in the circumferential direction (U), and-wherein the two grooves (7, 8) are arranged to be aligned in the axial direction (A). The invention further relates to a rotor arrangement (20) for an electric machine for an electric or hybrid vehicle, to an electric machine for an electric or hybrid vehicle, and to a method for producing a positioning means (6) in a rotor carrier (1).
