Abstract: A linear motor may comprise a first member including a plurality of amature modules; and a second member including a permanent magnet module that includes a plurality of permanent magnets, of which the poles are alternated in a first direction along which the plurality of amature modules are arranged, wherein each armature module includes a magnet core including a connection part, and two or more salient poles protruding from the connection part, and a coil carrying a current of the same phase and wound around the magnetic core; wherein the permanent magnet module is disposed between two salient poles of the amature module; and wherein a distance between two neighboring armature modules is larger than a distance between two neighboring salient poles within the same amateur module.

Abstract: A method for manufacturing a magnet module. The method may include injecting a magnet module including a plurality of magnetless magnets arranged in a straight line; and magnetizing the plurality of magnetless magnets mounted on the injected magnet module. The injecting of a magnet module may include mounting the plurality of magnetless magnets to a first part forming a frame of the magnet module in a mold frame including first and second mold frames molded inside to fit an external shape of the magnet module; injecting a resin in a liquid state into the mold frame; and separating the mold frame when the resin is hardened. The injecting of a magnet module may further include mounting a metal plate to a second part forming a base of the magnet module in the mold frame, before performing the step of injecting a resin in a liquid state into the mold frame.

Abstract: A linear motor is provided. The linear motor according to an embodiment of the present disclosure may comprise: a primary member including a plurality of armature modules, each armature module including a magnet core including two or more protruding portions and a coil; and a secondary member including at least one magnet module. The primary member may be fixed and a movable member composed of the secondary member moves by generated thrust. And, along the moving direction, a first interval between first armature modules disposed in a first section may be different from a second interval between second armature modules disposed in a second section after the first section.
