Disclosed therein is a method of operating a variable magnetic flux motor. Each transmitter and receiver module may comprise at least one antenna coil with a magnetic moment orientation not limited to the tool longitudinal direction. The second connection part is thereby formed by a sleeve, which is produced from a platelet by way of deformation and whose adjoining edges are provided with opposed projections and cutouts corresponding with the projections. At the end of the animation, the back side is displayed, and is larger than the initial front side image.
