ABSTRACT:
A linear guide with an integrated linear motor, the linear guide having a stationary support extending in a guide direction, a table movable in the guide direction and a linear motor. The linear motor includes 1) a movable element connected with the table, 2) a stationary element connected with the stationary support and contactless bearings between the stationary support and the table and 3) an electromagnetic positioner based on electromagnetic interaction for positioning the table transversely in relation to the guide direction. The linear guide includes an integrated position-measuring system having a scale and scanning heads which detect a position of the table in the guide direction and a deviation direction, which lies transversely in relation to the guide direction and parallel in relation to a plane of an air gap of the linear motor. The electromagnetic positioner acts in such a way so that the table is positioned in the deviation direction.
