回路。 Center the center yoke into which the drive coil is inserted, so that the center yoke sides are of the same polarity.
In a magnetic circuit for a DC linear motor, which is constructed by placing back yokes with permanent magnets fixed on top and bottom, the permanent magnets fixed on the back yokes have a high magnetic flux density at both ends in the direction in which the drive coil reciprocates. The thickness in the magnetization direction of the permanent magnets placed at both ends of the back yoke is made thicker than the thickness in the magnetization direction of the permanent magnet placed in the center of the back yoke, so that the thickness of the permanent magnets placed in the center of the back yoke and the back yoke is A magnetic circuit for a DC linear motor, characterized in that the magnetic circuit has a soft magnetic yoke provided between the magnetic circuits.
