Abstract

The present invention relates to a linear motor. According to one embodiment of the present invention, a linear motor may comprise: a primary member including a plurality of armature modules; a secondary member including a plurality of permanent magnet modules; and a supporting member. Each armature module has two or more salient poles projecting from an arcuate magnetic body toward the secondary member, coils, through which current of the same phase flows, are wound at each salient pole, each permanent magnet module has permanent magnets, having the same number of poles as the salient poles included in each armature module, disposed thereon, S armature modules disposed in a direction of movement and P (where P is a multiple of 2) permanent magnet modules are grouped as one unit, electric power having a predetermined phase difference for generating motive force by means of moving magnetic fields is applied to each armature module, and either one of the primary member or the secondary member, as the driver, is moved by the generated motive force, while the other, as the stator, is fixed to the supporting member. Accordingly, a motor can be provided that solves problems caused by magnetic pull, is easy to assemble and highly efficient, and enables movement over long distances.
