Rotor for a dynamoelectric machine, comprising 1.1 winding elements which are arranged in axially extending grooves of a rotor body, 1.2 a winding head which is arranged axially adjacent to the rotor body, wherein, in the region of the winding head, the winding elements emerge from the grooves in the axial direction, then extend at an angle to the axial direction and then, in the region of their axial ends, extend in the axial direction again and are connected to other winding elements, 1.3 a winding head carrier which is arranged radially inside of the winding head, 1.4 the winding head is connected to the winding head carrier by way of tension bolts which, at their radially outer ends, bear against support bodies which in turn rest on the winding elements in the region of the winding head, 1.5 the tension bolts pass through the winding head in the radial direction in the axially extending regions of the winding elements or in the regions in which the latter bend out of the axial direction into the direction extending at an angle to the axial direction, 1.6 the support bodies form at least two circumferential segmented annular assemblies which are spaced apart in the axial direction, 1.7 the tension bolts are screwed into profile bodies which are arranged in the region of the winding head carrier in corresponding, axially extending profile grooves or profile groove sections, characterized in that 1.8 the tension bolts are fastened in the region of the winding head carrier in such a way that a mobility of the support bodies in the axial direction is provided, whereby 1.9 the tightening torque of the tension bolts is selected such that a slight movement of the profile bodies in the profile grooves or profile groove sections in the axial direction is possible in order to compensate a relative movement of the support bodies relative to the winding head carrier. 1.1 winding elements which are arranged in axially extending grooves of a rotor body, 1.2 a winding head which is arranged axially adjacent to the rotor body, wherein, in the region of the winding head, the winding elements emerge from the grooves in the axial direction, then extend at an angle to the axial direction and then, in the region of their axial ends, extend in the axial direction again and are connected to other winding elements, 1.3 a winding head carrier which is arranged radially inside of the winding head, 1.4 the winding head is connected to the winding head carrier by way of tension bolts which, at their radially outer ends, bear against support bodies which in turn rest on the winding elements in the region of the winding head, 1.5 the tension bolts pass through the winding head in the radial direction in the axially extending regions of the winding elements or in the regions in which the latter bend out of the axial direction into the direction extending at an angle to the axial direction, 1.6 the support bodies form at least two circumferential segmented annular assemblies which are spaced apart in the axial direction, 1.7 the tension bolts are screwed into profile bodies which are arranged in the region of the winding head carrier in corresponding, axially extending profile grooves or profile groove sections, characterized in that 1.8 the tension bolts are fastened in the region of the winding head carrier in such a way that a mobility of the support bodies in the axial direction is provided, whereby 1.9 the tightening torque of the tension bolts is selected such that a slight movement of the profile bodies in the profile grooves or profile groove sections in the axial direction is possible in order to compensate a relative movement of the support bodies relative to the winding head carrier.
