Abstract:
An end structure for a rotor of an electric machine is attachable to an end of the rotor. The end structure includes a ring arrangement, a rotational axis of which is parallel to that of the stacked rotor, and at least one reinforcing structure at least partly within the ring arrangement. A value of a tensile strength of the at least one reinforcing structure is higher than that of the ring arrangement.
