The invention relates to a method which is used to produce rotors or stators of electric machines, wherein the rotors or stators have radial grooves, into which the webs of flat windings (26) having parallel webs and having winding heads (92) connecting said webs are pulled, wherein the flat windings (26) are prefabricated on a rotating, strip-shaped flat former (20) and the initially flat windings are pulled into the radial grooves (74) of a stator or of a transfer tool (44) for transfer into the grooves of a rotor. In order to enable continuous processing, the winding (26), according to the invention, is produced on a former (20) that is shorter than the entire winding such that the first produced windings are pulled off the former (20) before the production of the winding (26) is concluded, the pulled-off windings are transferred into a linear transfer device (28), which transports the finished windings to a removal position synchronously with the production of windings on the former (20), at which removal position the windings are transferred into the radial grooves of the stator or into the radial grooves (74) of the transfer tool (44) for transfer of the winding (26) into the radial grooves of the rotor, wherein the former (20), the transfer device (28), and the stator or the transfer tool (44) are always jointly rotated about the axis of rotation of the former (20) when the former (20) is rotated in order to form windings.
A method for producing rotors or coils of electric machines, wherein the rotors or stators have radial grooves into which webs of flat windings (26) with parallel webs and winding heads (92) connecting the latter are inserted, wherein the flat windings (26) are prefabricated on a rotating strip-shaped flat former (20) and the initially flat windings are inserted into the radial grooves (74) of a stator or a transposing tool (44) for passing on into the grooves of a rotor, characterized in that the winding (26) is generated on a former (20) which is shorter than the whole winding such that the first turns generated are removed from the former (20) before the production of the winding (26) is complete, the removed turns are transposed into a linear transfer device (28) which, at the same time as turns are generated on the former (20), transports the finished turns to a removal position where the turns are transposed into the radial grooves of the stator or into the radial grooves (74) of the transposing tool (44) for transposition of the winding (26) into the radial grooves of the rotor, wherein the former (20), the transfer device (28) and the stator or the transposing tool (44) are jointly rotated about the axis of rotation of the former (20) whenever the former (20) is rotated in order to form turns.
A device for producing rotors or stators of electric machines, with a winding device (10) which has a winding head (16) with a rotatable former (20), wire shifters (22, 24) and a wire feed device (84) for generating a winding (26) with multiple turns, consisting of parallel webs and winding heads (92) connecting the latter, and a transfer device (28), for transposing the winding (26) onto the stator, or a transposing tool (44) for subsequently transposing the winding (26) onto the rotor, characterized in that the former (20) is shorter than the winding (26) to be generated and a rotating device is provided which effects a synchronous rotation of the former (20), the transfer device (28) and the stator or the transposing tool (44) about the axis of rotation of the former (20) at least when the winding (26) extends from the former (20) to the stator or the transposing tool (44).
