    摘要: A motor includes a magnet assembly to generate a magnetic field. The field includes along the first direction parts which are alternately orientated in the first and the second direction. The parts extend in a third direction which is perpendicular to the first and the second direction. The motor further includes a first coil winding to carry a first current. The first coil winding to extend in the first direction between parts of the magnetic field orientated in the second direction, to generate the force in the first direction. The motor also includes a second coil winding to carry a second current. The second coil winding to extend in the first direction between parts of the magnetic field substantially orientated in the first direction, to generate the force in the second direction.

    摘要: Lithographic apparatus includes a substrate table and a motion control system for controlling a movement of the substrate table. The motion control system includes at least 3 position detectors constructed for detecting a position of the substrate table. For measuring a position and orientation of the substrate table, each position detector comprises an optical encoder of a single dimensional or multi dimensional type, the optical encoders being arranged for providing together at least 6 position values, at least one position value being provided for each of the 3 dimensions. 3 or more of the at least 3 optical encoders being connected to the substrate table at different locations in the 3 dimensional coordinate system. The motion control system is arranged to calculate the position of the substrate table in the 3 dimensional coordinate system from a subset of at least 3 of the 6 position values and to calculate an orientation of the substrate table with respect to the coordinate system from another subset of at least 3 of the 6 position values. Further, a method for calibrating the position detectors is described.
