Method for manufacturing a rotor for an electrical machine with an axial fixing of a laminated core by means of friction welding, as well as a rotor

A method for manufacturing a rotor (1) for an electrical machine having a rotor support (10) and a laminated core (4), comprising the steps of:

• positioning the laminated core (4) on a first component (2) of the rotor support (10), wherein the laminated core (4) at least partially radially encloses the first component (2) relative to an axis of rotation (12) of the electrical machine;
• and
• welding an axial end face of the first component (2) of the rotor support (10) with a second component (3) of the rotor support (10) to form the rotor support (10) by friction welding such that a welded joint running in a peripheral direction relative to the axis of rotation (12) arises wherein the welded joint forms a first weld bead (6), wherein the laminated core (4) is fixed on the rotor support (10) by a first fastening element (5) and a second fastening element (7) which respectively enclose the laminated core (4) on both sides of the laminated core (4) in an axial direction, by reducing a size of an axial extension of the first component (2) and/or of the second component (3) relative to the axis of rotation (12);
• wherein the first fastening element (5) is formed by the first weld bead (6).
