Abstract: A device for bending a plurality of winding segments to form a winding of a winding carrier of an electric machine is provided. The device includes: a holding device designed for holding in place the winding carrier in which the winding segments are arranged; a main bending device, including a number of main locking elements, which point towards the holding device, are arranged along first sections of a circumferential line and are designed to lock exposed end sections of first winding segments; and a partial bending device, including a number of partial locking elements, which point towards the holding device, are arranged along second sections of the circumferential line and are designed to lock exposed end sections of second winding segments. The holding device on the one hand and the main bending device and the partial bending device on the other hand are rotatable relative to each other.

Abstract: The disclosure relates to a method for producing a stator, where, for one or both layers of a two-layer winding, a tool with receiving regions is respectively provided on an end face of a laminated core. A relative arrangement of the receiving regions corresponds to a relative end position for conductor ends of the conductor elements. In a positioning process, the tool is moved into a first turning position and each conductor end of a first group of the conductor elements is respectively inserted into one of the receiving regions. Then the tool is turned into at least one further turning position and each conductor end of a further group of the conductor elements is respectively inserted into one of the receiving regions until the conductor ends of all the conductor elements of the layer are in the relative end position in relation to one another.

Abstract: The disclosure relates to a method for producing a stator. Electrical conductor elements are arranged in slots of a laminated core of a two-layer winding. The conductor ends of the conductor elements are moved relative to one another on an end side of the sheet metal packet at one or both of the layers by a positioning process by axially plugging together a normal helix tool with the axial conductor ends of some of the conductor elements and subsequent relative rotation of the normal helix tool relative to the sheet metal packet, and by axially plugging together a selective skewing tool with the axial conductor ends of the remaining conductor elements, such that they have a provided relative end position with respect to each other for a connection of a part of the conductor ends with corresponding conductor ends of the other layer.
