摘要

An electric motor includes a primary part for producing a traveling magnetic field and a secondary part for providing a static magnetic field, wherein the secondary part and the primary part are movable relative to one another under an effect of the travelling magnetic field. The secondary part has a device with a substrate and a conductor track, which track is applied to the substrate, in the form of a layer structure, wherein the conductor track can be supplied with an electric current for the purpose of producing the static magnetic field.
