  • 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
    Publication number: 20230336059
    Abstract: A method for manufacturing a rotor for an electrical machine having a rotor support and a laminated core includes positioning the laminated core on a first component of the rotor support, where the laminated core at least partially radially encloses the first component relative to an axis of rotation of the electrical machine. The method further includes welding an axial end face of the first component of the rotor support with a second component of the rotor support to form the rotor support by friction welding, where the laminated core is fixed on the rotor support by fastening elements which respectively enclose the laminated core on both sides of the laminated core in an axial direction. At least one of the fastening elements is formed by a weld bead.
