发明名称 DRIVE FOR AN XY-TABLE AND XY-TABLE
摘要 A drive for an XY-table includes a stationary, ferromagnetic and U-shaped yoke including a first limb and a second limb which are located together in one plane, and having a movable ferromagnetic bar, the yoke and the bar carrying a magnetic circuit with a flux that takes a path across air gaps between the limbs and the bar, and causes vertical reluctance forces there which counteract the gravitational force of the bar. Bar is parallel to and below the plane defined by the limbs.

主权项 1. A drive for an XY-table, comprising: a stationary, ferromagnetic and U-shaped yoke having a first limb and a second limb that are located together in a plane; and a movable ferromagnetic bar; wherein the yoke and the bar are adapted to carry a magnetic circuit with a magnetic flux that takes a path across air gaps between the limbs and the bar, and causes vertical reluctance forces in the air gaps that counteract a gravitational force of the bar; and wherein the bar is parallel to and below the plane.
