An iron-core linear motor forcer (100) with integrated aerostatic bearing guidance is disclosed. The motor forcer (100) comprises



(i) an iron-core (10) enclosed within an enclosure (13) having an upper surface (11) and a bottom surface (12), wherein the iron-core (10) is mounted with a plurality of coil windings (16), and a plurality of air supply channels (50) are provided substantially in vertical from the upper surface (11) to the bottom surface (12) of the enclosure (13), and each of the air supply channels (50) is terminated at the bottom surface (12) with one or more orifices (32); and
(ii) a linear motor stator (20) having a stator surface (22).




The iron-core linear motor forcer (100) is frictionless moving on the motor stator (20).
