ABSTRACT:
A laminated platen for use with linear motors and the like having a laminated substructure comprised of ferromagnetic plates interspersed with insulating plates. Spaced parallel grooves are formed in the subsurface lamination in which a transverse lamination structure of alternating ferromagnetic and insulator plates are arranged to significantly reduce eddy currents in mutually perpendicular directions. A grid-like pattern is machined into the operating surface and cooperates with electromagnets in the linear motor to affect movement of linear motor along said operating surface in mutually perpendicular directions. Plural linear motors may be operated upon a common surface.
