Abstract: A method for producing a formed coil winding includes providing a main body having a plurality of slots distributed across the circumference for arranging layered coils; providing at least one layered coil having a first coil side and a second coil side; arranging the first coil side in a slot in the main body, wherein the layered coil forms a projection at each of the two ends of the main body; form-fittingly and/or frictionally holding the first coil side in an exit region from the slot for holding the first coil side in the slot in a rotationally fixed manner; twisting the coil sides relative to one another in a circumferential direction until the second coil side is aligned with another slot in the main body; and radially shifting the second coil side for arrangement in the other slot.

Abstract: A method for producing a single- or multi-layer coil, includes the steps of: providing a flat wire; deforming the flat wire along a deforming direction in order to produce one or more winding sections which are designed to be offset relative to a starting section of the flat wire, wherein the one or more winding sections are designed to form coil layers which run on winding planes arranged in an offset manner relative to the deforming direction; and winding the one or more winding sections on the respective winding plane in order to form one or more coil layers.

Abstract: An arrangement of a contact element on free coil conductor ends of an electric machine is provided. At least one coil conductor end is inserted into an insertion opening of an assigned contact sleeve on the contact element and is welded to the contact sleeve. The contact element is configured to connect at least two coil conductor ends and/or electrically connect the at least one coil conductor end to at least one phase conductor, and the at least one coil conductor end lies against a wall which delimits the insertion opening of the contact sleeve on the inside over the entire circumference of the coil conductor end at least in a longitudinal region in the insertion direction of the coil conductor end into the contact sleeve.
