電磁型吸着装置。 A low coercive force magnet with an excitation coil wound around the outer periphery and a high coercive force magnet arranged in parallel or around the outer periphery of the excitation coil are fixed to the other side of the magnetic pole piece, one side of which is an attractive surface, and the magnetic pole piece is fixed to the other side of the magnetic pole piece. At least the other end of the permanent magnet is connected to the inner surface of the yoke cup, which is encapsulated so that the attracting surface is exposed, and the low coercive force magnet is magnetized in the same direction as the high coercive force magnet when a magnetic body is attracted,
In a permanent electromagnetic attraction device in which a low coercive force magnet is magnetized in the opposite direction to a high coercive force magnet when not attracted, a magnetic shorting piece is inserted between the outer circumferential surface of the high coercive force magnet and the inner circumferential surface of the yoke cup. A permanent electromagnetic adsorption device characterized by:
