Abstract
A linear motor includes an armature and a field magnet that are disposed to face each other and configured to be subjected to relative movement. The armature includes a plurality of windings that are arranged along a direction of the relative movement. Each of the windings is wound around a first iron core. The field magnet includes a plurality of permanent magnets that are disposed to face both sides of the armature in a direction perpendicular to the direction of the relative movement, and are arranged along the direction of the relative movement. A ratio of a dimension of the first iron core to an arrangement pitch of the windings in the direction of the relative movement is in a range from 0.1 to 0.35.
