ABSTRACT:
An aligner or positioning system for moving a member in any direction in a horizontal plane includes a planar member having an upper horizontal surface and a platform movable above the horizontal surface. Driving coils extending along either of two orthogonal directions are disposed in one of the members while a pattern of oppositely magnetized permanent magnet elements is disposed in the other in flux coupling relationship. Energization of windings in appropriate senses, in accordance with the position of the platform, generates relative movement in one or both of two orthogonal directions, which may include angular movement as well.
