を特徴とする可動コイル型リニアモータ。A yoke having permanent magnet pieces on one side that are magnetized in the thickness direction and arranged alternately in the longitudinal direction so that each magnetization direction is different, a center yoke arranged opposite to the permanent magnet pieces, and the yoke and the center. A magnetic circuit consisting of a side yoke that holds a yoke and generates magnetic flux in the air gap between the permanent magnet piece and the center yoke, and a magnetic circuit that can move within the air gap in a direction perpendicular to the magnetic flux and that is mounted on a coil bobbin. In a moving coil type linear motor configured by a moving coil having two winding portions whose winding width is approximately half of the width of one piece, a material with high magnetic permeability is used in the portion facing the air gap above the center yoke. A pair of wire rods made of a conductor made of a conductor with a low resistivity and a wire rod made of a conductor with a low specific resistance are combined so as to be alternately arranged adjacent to each other on the center yoke 3, and have a winding formed perpendicularly to the longitudinal direction of the center yoke. Moving coil type linear motor.
