<p>A mechanical translator includes at least one magnet (20) that is disposed on a substrate (22) to carry a load and has a magnetic axis generally transverse to the substrate, establishing a magnetic field with maximum external density adjacent the substrate. An ultra low friction interface is obtained with ferrofluid bearings (24), such as a light mineral oil medium mixed with isoparaffinic acid, which establish a critical angle of displacement from a horizontal static position of less than 1 degree, and preferably less than 10 minutes. A controller (46) of magnetic material can be placed on the opposite side of the substrate (32) to control the movement of the magnets (36).</p> |
