ていることを特徴とする自己保持型電磁石。A permanent magnet piece is disposed between magnetic yoke pieces formed in a substantially U-shape so that an armature can be attracted to the tip of the yoke piece, and a coil wound around the yoke piece generates magnetic flux due to the permanent magnet piece. In a self-holding electromagnet that attracts and releases the armature from the yoke piece by generating a magnetic flux in a direction opposite to that of the yoke piece, the lower end of the permanent magnet piece is aligned with the lower end of the contact portion of the yoke piece, and the yoke piece The interval for inserting the permanent magnet pieces is narrower than the interval for coil winding (the outer dimensions of the yoke attachment part are narrower than the outer dimensions of the winding coil, and the upper end of the permanent magnet piece is aligned with the lower end of the coil). Features a self-holding electromagnet.
