Patent ID: 8922088

Claim:
A rotor for a dynamoelectric machine, comprising: winding elements which are arranged in axially extending grooves of a rotor body; a winding head which is arranged axially adjacent to the rotor body, wherein in a region of the winding head the winding elements exit the grooves in the axial direction, then extend at an angle to the axial direction, and then extend in the axial direction again in the vicinity of the axial ends of said winding elements and are connected with further winding elements; and two respective winding elements exit in the axial direction from each of the grooves, wherein after a section in the axial direction the one of the winding elements extends at an angle to the right in relation to the axial direction and the other of the winding elements extends at an angle to the left in relation to the axial direction, and thereafter the winding elements extend in the axial direction again in the region of their axial ends and have a connection with other winding elements; a winding head carrier which is radially arranged within the winding head; the winding head is connected with the winding head carrier by means of tension bolts which engage at the radially outer ends thereof on support bodies, which in turn lie on the winding elements in the region of the winding head; the tension bolts are arranged between the rotor body and the first crossing of winding elements and between the last crossing of winding elements and the connection, as seen from the direction of the rotor body; the tension bolts penetrate the winding head in the radial direction in the axially extending areas or the areas of the bending of the winding elements from the axial direction to the direction extending at an angle from the axial direction; the support bodies form at least two circumferential segmented annular arrangements spaced in the axial direction; the tension bolts are fastened in the region of the winding head carrier in such a way that mobility of the support bodies in the axial direction is provided; and 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.
