Abstract
An elevator, particularly for transporting passengers, has an elevator car guided in an elevator shaft a direct drive motor. The drive motor includes an active primary part at the elevator car and a passive secondary part that is fixed in the elevator shaft and is spaced from the primary part by an air gap. In order to achieve a high power capability, the drive motor is configured as a transverse flux motor that moves the primary part linearly relative to the secondary part under the influence of an electromagnetic propulsive force. The secondary part has at least one rail made of a soft magnetic material and subdivided into a plurality of segments having a predetermined length. The segments are fixed to a wall of the elevator shaft by intermediate elements.
