Abstract
A linear motor includes an armature coil and a field magnet formed of a plurality of alternately arranged magnetic poles of N- and S-poles, one of the armature coil and the field magnet forming a stator element of the linear motor, and the other forming a movable piece element of the linear motor movable with respect to the stator element. The armature coil has a polygonal section perpendicular to a relative moving direction of the armature coil with respect to the field magnet, and the field magnet is opposed to at least two continuous side surfaces among side surfaces of the armature coil extending along the relative moving direction and has an integral bent form extending along these continuous side surfaces.
