A linear DC brushless motor is provided with a discriminating element, and one of the magnetic field magnets and the coreless armature having the magnetic pole discriminating element is used as a relatively movable mover, and the other is used as a stator, comprising the following components. Features a linear DC brushless motor. The length and width of the armature coil in the direction perpendicular to the moving direction of the moving element are approximately equal to the width of the field magnet in the direction perpendicular to the moving direction of the moving element. The armature coil is located at the outer periphery of one corner of the armature coil, which intersects at a conductor extension position perpendicular to the moving direction of the mover and at a conductor extension position parallel to the mover movement direction. A corner conductor portion of one of the armature coils is wound inward to provide a space for arranging the magnetic pole discriminating element so that the magnetic pole discriminating element can be disposed at a position so as not to overlap with the armature coil. be formed in an air-core shape that allows for A conductor portion of the armature coil that contributes to the generation of thrust in a direction perpendicular to the direction of movement of the mover and a conductor portion of the armature coil in a direction parallel to the direction of movement of the mover intersect and do not overlap with the armature coil.
