Abstract:
A method for producing a wave winding for stators or rotors of electric machines, wherein at least one winding wire (18), which is fed in by a wire guide (20), is wound on a shaping body (10) designed with recesses (16) of a template (10, 12), which can be rotatingly driven, and is cyclically pressed into the respectively allocated recesses (16) in the course of the creation of each winding of the wave winding by means of radially movably guided exterior shaping elements (12) of the template as a function of its angle of rotation position, and thereafter the windings are transferred into longitudinal slits of a coil receiver (34), which can be positioned axially in front of the shaping body (10) and is held, fixed against relative rotation, or performs a positioning movement during the creation of the windings, wound without breaks in the wire, characterized in that the shaping of the end of the last winding of the wave winding is finished by at least one shaping element (12) close to the wire guide (20) in the allocated recess (16), wherein the latter shaping element (12) is moved radially inward in addition to the cyclically performed shaping movement.
