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 (N1 to N36; N1 to 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.

Abstract: A tool clamping device comprises a support which is mounted on or is adapted to be mounted on the bed, carriage or saddle of a turning machine, such as a lathe. A tool holder, in which a tool is clamped, is itself clamped between two mutually facing parallel clamping surfaces on the support by spreading means. Prior to clamping the tool holder between the clamping surfaces it is guided by at least one guide on the support, e.g. during coarse and fine adjustment of the position of the tool holder. The latter is also provided with actuation members for the tool clamping means and the spreading means. The tool can be clamped to the tool holder while the latter is removed from the support so as to form a replaceable tool cartridge.
