Abstract: A method of stacking wave winding wires (wires) for forming a winding mat for a stator coil winding including providing a drop magazine containing a plurality of similar wires in a receiving space, wherein a receiving space contour is configured to the received wires, such that the wires are positioned at a plurality of guide devices at different receiving space boundary locations and guided through the receiving space without changing their geometry, positioning a workpiece carrier having a retaining structure for a winding mat formed of multiple stacked wires in a first transfer position below the magazine and depositing a wire from the magazine at a first position on the workpiece carrier, positioning the workpiece carrier in a second transfer position offset from the first transfer position below the magazine, and depositing a further wire from the magazine at a position offset from the first position on the workpiece carrier.

Abstract: A device and method for producing a plugged wave winding by plugging together first and second wave winding parts. A first receptacle receiving the first wave winding part includes elements for guiding first wave winding part straight wire sections. A second receptacle receives the second wave winding part and has elements for guiding second wave winding part straight wire sections. A device for bending portions of at least one of the wave winding parts is configured to displace one or more of the winding heads directed towards the other wave winding part to plug the wave winding parts together. A relative displacement device pushes and plugs the first and second wave winding parts into one another. The first and/or second guide elements are movable between a position for guiding the straight wire sections and a position for releasing the path of winding heads while plugging into one another.

Abstract: A pre-fitting nest and a method serve for forming a crown from a plurality of U-shaped electrically conductive hairpins to then be able to install the crown in a machine element of an electric machine, e.g., a stator. Here, an accommodating member has a plurality of grooves in which the legs of the hairpins are accommodated. The grooves are annularly disposed about a center and extend perpendicularly to the plane of the accommodating member. With respect to their size and geometry, they are configured such that in each case a first leg of a hairpin rotates within the groove thus to enable an unconstrained positioning of the second leg of the hairpin in another groove. One or several crowns formed from hairpins are provided for introduction into a machine element and inserted into the machine element.

Abstract: A mounting device for inserting magnets into magnet accommodating portions of a rotor of an electric machine. The mounting device comprises an aligning device configured to accommodate and align the magnets by means of at least one channel. In this case, a shape of the at least one channel is adapted to a shape of the magnets. The channel comprises a channel inlet, which is disposed at an end face of the aligning device and via which the magnets can be fed to the channel, and a channel outlet, which is disposed opposite the channel inlet and is disposed at an end face of the aligning device opposite the end face and via which the magnets can be discharged from the channel. Furthermore, the at least one channel is twisted.
