Abstract:
A stator for planar motors comprising:(a) at least two temporarily conjoined rectangular platen tiles, each a stator having substantial rigidity and substantial planarity comprising operative surface means providing reactive forces for at least one planar motor in operative juxtaposition thereon; (b) said operative surface means having one or more operative feature means arranged in an array precisely aligned with respect to the edges of said platen tiles and providing electromagnetic interaction with opposing elements of said planar motor; c) said platen tiles having dimension n&lgr;Ã—m&lgr; where n and m are positive integers, said array having periodicity &lgr;, thereby permitting unbroken continuity of said operative feature means when at least two said platen tiles are temporarily conjoined; (d) in combination, said platen tiles and mechanical attachment means ensuring substantial co-planarity of said operative surface means of said platen tiles and substantially precise alignment of said edges of said platen tiles, said mechanical attachment means operable in reverse to unattach said platen tiles; whereby a contiguous ensemble of said platen tiles forms a single continuous said operative surface means of said stator for at least one said planar motor.
