The invention relates to a rotor (6) for a dynamo-electric machine (7) having: a rotor body (10) which rotates about a rotation axis (R) which runs in the direction of gravity (9), winding elements (14) which are arranged in slots (13) which run axially in the rotor body, two winding heads (9) which are arranged above and below the rotor body in the axial direction, wherein the winding elements emerge from the slots in the axial direction in the region of the winding heads and are connected to further winding elements, a winding head carrier (15) for each of the winding heads, which winding head carrier is arranged radially within the winding head and coaxially to the rotation axis, and which winding head carrier is fixed at least indirectly on the rotor body, or on a component which revolves with said rotor body, in a rotationally fixed manner and such that it can move in the direction of the rotation axis. The invention is characterized by the following features: spring elements (19) are provided in the region of the fixing means, said spring elements acting in the axial direction against the force of gravity (9) between the rotor body, and/or a component which revolves with said rotor body, and the winding head carrier (15), each of the winding head carriers (15) has at least one carrying ring (15.1,15.2) which is integral or is segmented in the circumferential direction, each of the carrying rings is mounted at least indirectly in relation to the rotor body (10) in the axial direction by means of spring elements (19).
