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.

Method for forming a crown from a plurality of U-shaped electrically conductive hairpins

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.
