Abstract

An arrangement for gripping metallic workpieces formed of ferromagnetic materials or electrically highly conductive materials, by means of electromagnetic forcs. In one embodimet, two linear-motor stators perform as gripping elements by producing travelling fields which exert gripping forces on the workpieces. The linear-motor stators may be configured to conform to the geometry of the workpieces, and are supported by at least one gripper arm.
