Winding overhang having recesses for improving the recovery behavior

An electric machine comprising a stator (12) and a winding (14) has a winding overhang (16) on the end faces of the stator (12), the winding overhang surface (18) of said winding overhang having recesses (20) in the axial direction of the stator (12). Said recesses (20) are designed such that a geometrical moment of inertia of the winding overhang (16) is increased in the axial direction of the stator (12). A device for producing a winding overhang (16) of an electric machine comprises a press tool (32) having elevations (44) which produces recesses (20) in a winding overhang surface (18) in order to increase a geometrical moment of inertia of the winding overhang (16). 具有定子（12）和绕组（14）的电机在所述定子（12）的端面处构造了绕线头部（16），所述绕线头部在其绕线头部表面（18）处沿着所述定子（12）的轴向方向具有凹处（20）。该凹处（20）以下述方式构造：使得所述绕线头部（16）的面积惯性矩沿着所述定子（12）的轴向方向提高。用于制造电机的绕线头部（16）的装置具有挤压工具（32），所述挤压工具具有凸起（44），所述挤压工具在绕线头部表面（18）处产生所述凹处（20），以用于提高绕线头部（16）的面积惯性矩。
