Abstract: In the formation of coil windings of an electrical machine, the invention provides a ring arrangement device for forming a ring arrangement from a plurality of concentrically arranged rings of electrical conductors to form a coil winding of a component of an electrical machine, comprising a collecting receptacle with a plurality of grooves arranged in a ring around an axis and delimited by radial webs and a ring positioning device for the relative axial positioning of one or more of the rings, wherein the ring positioning device has a support device for supporting the electrical conductors of one of the rings to be inserted in an axial insertion position and one holding device for holding the conductors in a storage position, in which the conductors of a completely inserted ring are moved further into the collecting receptacle.

Abstract: 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.

Abstract: A gripping apparatus for gripping at least one of several conductive members. The gripping apparatus is configured to grip different geometries of conductive members. The conductive member includes a first and a second conductive member end portion. The gripping apparatus includes a basic body, a first gripping device having a first gripper, wherein the first gripping device is configured to grip the first conductive member end portion or the second conductive member end portion of a predetermined conductive member via the first gripper. The gripping apparatus further has a second gripping device including a second gripper disposed to be movable relative to the basic body. The second gripping device is configured to move the second gripper relative to the first gripper such that the second gripper grips the predetermined conductive member at the second conductive member end portion or at the first conductive member end portion.

Abstract: In order to reduce the outlay in terms of apparatus and production technology in the formation of coil windings of an electrical machine, the invention provides a ring arrangement device (10) for forming a ring arrangement (82) from a plurality of concentrically arranged rings (14a, 14b, 14c) of preferably U-shaped electrical conductors to form a coil winding of a component of an electrical machine, comprising a collecting receptacle (12) with a plurality of grooves (24) arranged in a ring around an axis and delimited by radial webs (38) and a ring positioning device (26) for the relative axial positioning of one or more of the rings (14a, 14b, 14c), wherein the ring positioning device (26) has a support device (46) for supporting the electrical conductors of a ring (14a, 14b, 14c) to be inserted in an axial insertion position (16), in which the conductors protrude further from the collecting receptacle (12), and one holding device (48) for holding the conductors of a completely inserted ring (14a, 14b, 14
