モータ。[Claims for Utility Model Registration] An elongated stator having a pair of excitation units arranged in parallel, and a permanent magnet, which is provided facing the stator and is movable along the longitudinal direction of the stator. The excitation unit is formed from an elongated yoke, an excitation coil wound around the yoke along its longitudinal direction, and two magnetic pole bodies attached to the yoke, and these two The magnetic pole body has a large number of pole teeth arranged at a pitch four times the amount of one-pulse movement of the movable element,
The pair of excitation units are arranged so that their pole teeth are staggered, and the pair of excitation units are arranged so that their pole teeth are shifted by a pitch equal to one pulse movement of the movable element, so that the magnetic pole surface of the permanent magnet of the movable element is In a linear pulse motor, the magnetic poles are arranged alternately along the moving direction of the movable element at a pitch approximately twice the amount of one-pulse movement of the movable element, and the magnetic pole faces are closely opposed to the magnetic pole body, The magnetic pole body is formed of opposing yoke side wall portions that are connected to each other on both sides of the yoke, and the pole tooth that is integrally bent from the tip of the side wall portion. A linear pulse motor characterized in that the area is larger at the base side integrally connected to the yoke side wall part than at the tip side.
