Abstract
A rotor for an electrical machine includes a first shaft part and a second shaft part, which is arranged separately from the first shaft part. A first supporting element is connected in a manner fixed against rotation to the first shaft part, and a second supporting element is connected in a manner fixed against rotation to the second shaft part. The rotor has a yoke which connects the first supporting element to the second supporting element and includes a plurality of laminates arranged one behind the other, and which has cutouts extending in the direction of the axis of rotation in the interior of the yoke, and permanent magnets arranged in the cutouts. The yoke has holes extending in the direction of the axis of rotation, with tensioning pins extending through the holes in the yoke to brace the laminates.
