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 device for inserting electrical conductors into a machine element of an electric machine comprises a collection receptacle for providing an assembly of one or several crowns formed from electrically conductive hairpins, and an inserting device for removing the crown assembly from the collection receptacle and for introducing the crown assembly into the machine element. An associated method comprises the steps of: providing, in a collection receptacle, an assembly of one or several crowns of hairpins; removing the crown assembly from the collection receptacle; and introducing the crown assembly into the machine element which, in particular, is a stator or rotor of an electric motor.
