  • Driving means to position a load
    Publication number: 20040083929
    Abstract: The invention provides an apparatus and method for positioning a moveable mass, such as the moveable components found in a typical XY table. The apparatus comprises driving means producing a driving force to move the mass along an axis, which mass has a variable center of gravity position perpendicular to said axis. The driving force from the driving means is operative to act through the center of gravity of the mass as the position of the center of gravity changes.

  • Motor system for positioning a load
    Patent number: 6713903
    Abstract: The invention provides a motor system and a method for positioning a load. The system comprises support means such as an XY table for supporting the load. A first motor and a second motor cooperate to drive the load, whereby the first motor is adapted to provide higher thrust than the second motor and the second motor is adapted to deliver higher positioning accuracy than the first motor during a positioning sequence to position the load.
