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.
