A linear motor having an air bearing integrally is disclosed. The linear motor includes a “U” shaped frame having permanent magnets spaced from each other on its inner walls, an inverted “U” shaped frame spaced from outer walls of the “U” shaped frame at interval, having an extension frame for protecting the “U” shaped frame and having air injection openings for injecting air into both ends of a center frame, and an armature coil portion installed on the bottom surface of center frame and spaced from the permanent magnets at interval. Accordingly, a step difference between heights generated when the air bearing and the linear motor are installed, can be removed, and the linear motor can be cooled using the air applied to the air bearing.
