Abstract

The invention relates to an annular rotor having a hollow shaft for an electric machine. In order to allow transport of such a machine, particularly for a very large model, the rotor is divided in the circumferential direction into a plurality of partial annular rotor segments (1). The rotor further comprises a hollow shaft, wherein the closed ring shape of the rotor can be broken by separating the rotor segments (1) from each other.
