Abstract
A linear motor comprises a first member including armature modules, a second member including permanent magnet modules, and a supporting mechanism. Each armature module has at least four salient poles projected from a magnetic body to the second member and coils winding round the salient poles, through which a single-phase current flows. Each permanent magnet module has as many permanent magnets as the number of the salient poles included in each armature module. Currents having a predetermined phase difference are applied to the armature modules such that a thrust according to a traveling magnetic field is generated in a unit composed of S armature modules and P (P is a multiple of 2) permanent magnet modules arranged in a moving direction. A stator corresponding to one of the first and second members is fixed to the supporting mechanism such that a mover corresponding to the other moves by the thrust.
