ROTOR OF AN ELECTRIC MACHINE

The invention relates to a rotor (1) of an electric machine, said rotor comprising: a rotor carrier (3) which can be rotated about a rotor axis (2), in particular for arrangement on a rotor shaft (4); and a plurality of separate pole segments (5) which are fastened to the rotor carrier (3) and on each of which at least one magnet (6), in particular a permanent magnet, is provided and each of which form a rotor pole (7) having in each case a pole centre (8). The invention is characterised in that: each pole segment (5) has at least two separate sub-segments (10) which are positioned one behind the other, at a distance (a) from one another, in the radial direction with respect to the rotor axis (2) so as to create a layered intermediate space (11) between each pair of adjacent sub-segments (10) of each pole segment (5) in order to accommodate a layer of inserted magnets (6) or to accommodate a cast-in or injection-moulded magnet (6); and the pole segments (5) of the rotor (1) are enclosed in a sleeve-like manner by a rotor sleeve (15) which is in particular prefabricated or wound onto the rotor.
