Method for producing a formed coil winding, stator and mold for producing formed coil windings

A method for producing a formed coil winding, comprising:

• providing a main body comprising a plurality of slots arranged so as to be distributed on a circumference for arranging layered coils, wherein the main body extends along a longitudinal axis;
• providing at least one layered coil, wherein the at least one layered coil has at least one first coil side and at least one second coil side;
• arranging the at least one first coil side in a slot of the plurality of slots of the main body, wherein the at least one layered coil forms in each case one protrusion on both ends of the main body;
• holding the at least one first coil side in a form-fitting and/or force-fitting manner in a region of a first exit from the slot on a first end of the main body, so as to hold the at least one first coil side in a rotationally fixed manner in the slot, further comprising:
• arranging, at the first exit from the slot on the first end of the main body, a first interlock plate and a second interlock plate having contact faces oriented toward one another in a circumferential direction about the longitudinal axis of the main body;
• twisting the first and second interlock plates relative to one another in the circumferential direction such that the contact faces clamp the at least one first coil side to hold it in the slot in the rotationally fixed manner;
• twisting the at least one first coil side and the at least one second coil side along the circumferential direction relative to one another until the at least one second coil side is co-aligned with another slot of the plurality of slots of the main body;
• and
• radially displacing the at least one second coil side for arrangement in the another slot.
