Zusammenfassung:An apparatus for contactless transportation of a carrier is provided. The apparatus includes the carrier, being a substrate carrier or a mask carrier. The apparatus includes a linear reluctance motor for providing both a contactless levitation and a contactless drive of the carrier. The linear reluctance motor includes one or more linear stators defining a transportation track for the carrier. The linear reluctance motor includes a mover attached to the carrier. The linear reluctance motor includes a set of electromagnets and a first magnetic material. The one or more linear stators include the set of electromagnets and the mover includes the first magnetic material, or the mover includes the set of electromagnets and the one or more linear stators include the first magnetic material. The apparatus includes a controller connected to the set of electromagnets.
