Patent ID: 7459808

Claim:
A lithographic apparatus comprising a motor to generate a force in a first direction and a force in a second direction, the motor comprising: a magnet assembly to generate a magnetic field which comprises along the first direction parts which are alternately orientated in substantially the first and the second direction, the parts extending in a third direction substantially perpendicular to the first and second direction, a first coil winding to carry a first current, the first coil winding to extend in the first direction from a first part to a second part of the magnetic field substantially orientated in the second direction and along a third part of the magnetic field oriented along the first direction and located between the first and second parts, the first and second parts of the magnetic field to interact with the first coil winding to generate the force in the first direction, and 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 directions, wherein the first and the second coil windings are spaced apart from each other in the third direction.
