ABSTRACT:
The method of making an electromagnetically excitable core of an electrical machine with a multiphase winding (13) includes preparing a core (10) having a substantially parallelepiped shape, which is provided with a plurality of parallel grooves (N1to N36; N1to N48) in one side in a first step. In at least one subsequent step at least three phase windings (100, 200, 300) are laid in these grooves in such a manner that only one winding overhang is outside of the core.
