電磁石装置。[Scope of Claim for Utility Model Registration] (1) A magnetic material comprising a plurality of electromagnets arranged along a suspension beam and a control means for controlling the excitation state of each of the electromagnets, and suspended by the electromagnets. Lifted number detection means for detecting the number of boards to be made is provided, and when the control means detects that a required number or more of board materials have been lifted by the lifted number detection means, one of the electromagnets is activated. An electromagnetic device for lifting plate material, characterized in that it is equipped with a control means for instantaneous excitation interruption for instantaneously interrupting excitation of an electromagnet in the section. (2) The control means includes re-excitation control means for performing excitation at a current value larger than the current value before the instantaneous excitation interruption during re-excitation after the instantaneous excitation interruption by the excitation instantaneous interruption control means. An electromagnetic device for lifting plate material according to claim 1 of the registered utility model claim.
