Abstract
A rotor for electrical rotating machines includes a rotor core with axial grooves for receiving axial conductors. A first element on the axial grooves and a corresponding second element on the axial conductors interact with one another to fix the axial conductors in the axial grooves in particular with respect to centrifugal and torsional forces. The provision of structural features on the rotor in the grooves and corresponding features on the conductors allows a simple and direct assembly of the conductors to the rotor core without additional fixing means. A method of assembling such a rotor is also provided.
