A winding mat formed as a flat winding and to coil mat formed from it for producing a coil winding for an electric machine. To be able to manufacture different coil mats also with layer swap and conductor swap in an automated manner and in large series and with a high degree of reliability, it is proposed to join wave winding wires by plugging. To produce the coil mat, it is proposed, among other things, to join two individual mats by plugging the mats together.

Winding mat and coil mat comprising the same as well as electric machine component formed therewith and method of manufacturing the same

A bending unit for bending a bend of a wave winding for a coil winding of an electric machine, having a first holding element for holding a first segment of a wire to be bent, a second holding element for holding a second segment of the wire to be bent and at least one bending mold for bending a transition region of the wire between the first segment and the second segment. The first and the second holding elements are in engagement with each other via at least one mechanical control cam to control a relative pivoting and a relative displacement of the first and the second holding element. Furthermore, a bending device having a plurality of such bending units, a wave winding production apparatus having a plurality of bending units which are synchronized via control cams, and a bending method and a wave winding production method are described.

Unit, device, apparatus and method for bending and producing wave windings for coil windings of electric machines

A method and device for manufacturing winding mats for manufacturing a coil winding of an electric machine. The winding mat is composed of wave winding wires bent as a flat winding in one plane. To be able to manufacture different coil mats with improved electrical characteristics easily and reliably in large series, it is proposed not to interlace or twist the wave winding wires, but to plug them at least partially. In addition, a method and a device for manufacturing a coil mat from several winding mats designed as individual mats are proposed. The device preferably comprises an offsetting device for introducing height offsets into winding heads of the wave winding wires.
