Depending on the selected winding method, the individual coil strands of the windings lie unordered and uncompressed in the groove after the insertion process. To allow further phases to be inserted and to increase the mechanical copper filling factor, the windings are widened with the help of a forming machine and pressed into the bottom of the slot (intermediate forming). Once all phases have been inserted and the winding head has been fixed by lacing, the final forming process takes place (final forming). The machine forming thus ensures that the technical properties, especially the filling factor and the final dimensions, are achieved.

Our extensive equipment portfolio, consisting of winding machines, insertion machines, forming machines and lacing machines, completes the process chain for the production of stators.
By using flat wires, the fill factor, and thus the efficiency, of an electric motor can be significantly increased. With the innovative flat wire wave winding, drive concepts can be realised that set benchmarks in the area of power density. An ideal production technology for the challenges of e-mobility.
