Claims

[Claims for Utility Model Registration] (1) It has a central magnetic pole part and opposing magnetic pole parts facing each other across the central magnetic pole part, and the central magnetic pole part is magnetically coupled to the facing magnetic pole part, and the coil is excited. It is equipped with an electromagnetic block that has a polarity different from that of the opposing magnetic pole part, and a permanent magnet block that is made of a non-magnetic material and is made of two parallel permanent magnet pieces with a predetermined interval. The magnetic block is
It is combined with the electromagnetic block in such a way that the central magnetic pole part and the opposing magnetic pole part are inserted into the gap formed by the two permanent magnet pieces, and both blocks become relatively positive as the excitation state of the coil changes. An electromagnet device that moves in reverse, characterized in that the contact area between the central magnetic pole part and/or the opposing magnetic pole part and the two permanent magnet pieces is different on the positive side and the opposite side in the forward and reverse movement direction. electromagnetic device. (2) The electromagnet device according to claim 1, wherein the central magnetic pole portion is connected to the opposing magnetic pole portions at their respective extension portions, forming an E-shape as a whole.
