Summary:A rotor and a method of making such a rotor, wherein the rotor has a shaft, a longitudinal axis, and a rotor packet connected to the shaft at least in torsion-resistant manner. The rotor packet is assembled from individual sheet lamellae, wherein the rotor packet has an opening for receiving the shaft. The shaft is a hollow shaft with a wall, wherein the wall of the shaft has, on its side facing toward the opening, recesses extending in the longitudinal direction. An electric motor, in particular a synchronous or hybrid synchronous machine, including a rotor and a stator, has such a rotor. The recesses are produced by cutting methods, in particular milling, or reshaping methods, in particular pressing.
