Abstract
An electric machine includes a first active part, which has a plurality of active part segments disposed one behind the other in a direction of movement of the electric machine, with each of the active part segments including a position measuring device, and a second active part with a measuring device for identifying the respective position measuring device. Each position measuring device has at least one position measuring unit having a dielectric constant, wherein the dielectric constant of the position measuring unit in one of the active part segments is different than the dielectric constant in an adjacent one of the active part segments. The measuring device includes at least one measuring unit to determine the dielectric constant of the position measuring units.
