    摘要： The invention describes a production method for a closed form-wound coil (3) of a stator winding system (2) of an electrical machine (1) comprising a basic coil (21) with a rectangular coil cross section (14) with slot sides (4) and end sides (5), which has a plurality of rectangular conductor elements (16) which are electrically insulated from one another, with the aid of a coil forming machine (22). The coil forming machine (22) has lug holders (23), radius pieces (24) and guide elements (25). In the first step, the end sides (5) are held centrally by a lug holder (23), the slot sides (4a, 4b) are each held by at least two radius pieces (24), and the regions of the end sides (5) between the lug holders (23) and the radius pieces (24) are held by guide elements (25). In the second step, the two slot sides (4a, 4b) are spread by the radius pieces (24) and rotated in relation to one another such that they run parallel in accordance with the slot position. In the third step, the intermediate regions are bent into a defined end position by the guide elements (25) which bear against three sides in a force-fitting or interlocking manner.

    摘要： The invention relates to an active part of an electric machine, wherein the active part comprises at least two teeth (1), which each have a magnetically permeable material and which each protrude from a lateral surface (3) of the active part in a radial direction, and at least one winding groove (4), each of which is arranged between a pair of the at least two teeth (1), wherein the at least one winding groove (4) is arranged substantially along an axis of rotation (5) of the active part and wherein an electrical winding (6) can be arranged in the particular winding groove (4). The invention further relates to an electric machine having such an active part. In order to improve the cooling of an active part economically, the active part according to the invention has at least one open recess (10, 20, 30), each of which is arranged on or in a particular tooth (1) in a particular plane, wherein the particular plane is spanned by a substantially radial direction (2) and a direction substantially along the axis of rotation, and at least one heat-conducting element (11, 21, 31), which is arranged at least partially in the particular open recess (10, 20, 30) and which has a thermally conductive material, the thermal conductivity of which is greater than the thermal conductivity of the magnetically permeable material.
