Abstract

The rotor poles (5.1 to 5.7) are rigidly anchored by means of specially formed pole bases having design embodiments (4.3 and 4.4) comprising fastening elements (14.1 to 14.4, 21.1, 21.2, 22) in the rotor poles (5.1 to 5.7) and threaded joints having non-magnetic screws through the non-magnetic main rotor body (3) in the direction of the rotor poles (5.1 to 5.7) and orienting and mounting aids (18.1 to 18.15) for orienting and anchoring the rotor poles (5.1 to 5.7) on the main rotor body (3), wherein permanent magnets (1) separated by pole gap teeth (8) lie between the rotor poles (5.1 to 5.7) as magnetic bodies, wherein the pole gap tooth bases (8.2) are rigidly anchored by means of likewise design embodiments (4.1 to 4.9) comprising fastening elements (14.1 to 14.4, 21.1, 21.2, 22) in the pole gap teeth (8) and threaded joints having screws through the main rotor body (3) in the direction of the pole gap teeth (8) and orienting and mounting aids (18.1 to 18.15) for orienting and anchoring the pole gap teeth (8), and the pole gap teeth (8) are diminished from the pole gap tooth base (8.2) in the direction of the pole gap tooth crown (8.1) and thus the axis of symmetry of the permanent magnets (1) forms an angle to the radius of the rotor.
