ABSTRACT:
A method of constructing a linear drive motor assembly is disclosed. In accordance with the method, a support plate and a platen with a plurality of teeth are provided. A honeycomb core comprising a commercially available, off-the-shelf honeycomb material is provided. The honeycomb core has a plurality of cells arranged in a planar array where the plurality of cells is defined by walls extending in planes substantially perpendicular to the planar array. The support plate is directly secured to one side of the planar array. The platen is secured directly to the other side of the planar array. A forcer having a motor stack is magnetically coupleable to the platen to form a linear drive motor.
