  • the advantages that can be achieved with the invention are, in particular, that one compact, reproducible geometry of the winding arrangement results - d. H. it result very reproducible electrical values (inductance, capacitance) an additional subsequent, cost-intensive coordination (e.g. everyone individual winding in series production).
  • the one for the winding arrangement available space is used optimally, d. H. versus conventionally wound Space is saved in windings.
  • the winding arrangement is inexpensive to manufacture.
  • the general advantage of a three-dimensional winding is that the three-dimensional winding arrangement no special orientation depending on the magnetic field serving for energy supply always requires an optimal To achieve "energy yield".
