The rotor and stator include electric conductor paths leading to exciting coils and/or to electronic components, all arranged on an iron-plate serving as a magnetic return path. The iron-plate has at least one electrical insulating layer that serves to insulate it, as well as at least the conductive layer forming the conductor paths which are on the insulating layer.
