Abstract
The present invention relates to a linear traversing carriage for use in the papermaking industry and the like, which incorporates an air gap inductive motivator and eliminates all mechanical devices between the electrical power supply and the traversing mechanism. Specifically, the present invention relates to a linear traversing device comprising an inductor type linear motor comprising an electrical stator winding, a conductive platen extending over an entire traverse length of the device, a ferromagnetic material affixed to said conductive platen, a support means for supporting the device and maintaining an air-gap between the stator winding and the conductive platen, a user selected feed forward velocity map for driving the device, a controller that controls a movement of the device according to the user selected feed forward velocity map.
