The invention discloses a lifting electromagnet capable of accurately attracting multiple steel plates and a control method. The lifting electromagnet comprises a top plate and at least one electromagnet group fixed on the top plate, and each electromagnet group is provided with a plurality of different electromagnets; each electromagnet comprises a hollow inner magnetic pole, an outer magnetic pole, a coil and a junction box, the coils are wound on the hollow inner magnetic poles and connected with the junction boxes, and the outer magnetic poles are arranged on the periphery of the coils; and the wall thicknesses of the outer magnetic poles of different electromagnets are different. According to the lifting electromagnet, the at least one electromagnet group is arranged, each electromagnet group is provided with the plurality of different electromagnets, the wall thicknesses of the outer magnetic poles of the different electromagnets are different, so that steel plates with different thicknesses can be attracted and lifted, and therefore, the plurality of steel plates can be accurately attracted and lifted.
本发明公开了一种精确吸吊多张钢板的起重电磁铁和控制方法,起重电磁铁包括顶板和固定于顶板上的至少一组电磁铁组,每组电磁铁组具有多个不同的电磁铁;电磁铁包括中空内磁极、外磁极、线圈以及接线盒,线圈绕在中空内磁极上并与接线盒连接,外磁极设置在线圈的外周;不同的电磁铁的外磁极的壁厚不同。本发明公开的起重电磁铁通过设置至少一组电磁铁组,每组电磁铁组具有多个不同的电磁铁,不同的电磁铁的外磁极壁厚不同,进而可以实现对不同厚度的钢板的吸吊,从而精确吸吊多张钢板。
