永(yong)(yong)磁吸盤和電(dian)磁吸盤都是(shi)利用磁場作用來(lai)吸住具有導磁性能(neng)的(de)工件(jian)。但(dan)使用時間過長(chang)永(yong)(yong)磁吸盤磁力會(hui)減弱，故(gu)要重(zhong)新充磁。永(yong)(yong)磁吸盤不需供電(dian)，也不因通電(dian)而發熱，故(gu)工件(jian)受熱變形小，能(neng)獲(huo)得較高的(de)加工精度。

當前隨(sui)著人類(lei)生產活動規模的(de)(de)不(bu)(bu)斷擴(kuo)大，為(wei)了提高生產效率(lv)，永(yong)(yong)(yong)磁(ci)(ci)吸(xi)盤(pan)(pan)和(he)電(dian)磁(ci)(ci)吸(xi)盤(pan)(pan)也愈來愈趨向(xiang)高速化和(he)自動化的(de)(de)方向(xiang)發展。電(dian)永(yong)(yong)(yong)磁(ci)(ci)吸(xi)盤(pan)(pan)的(de)(de)吸(xi)持(chi)力比較穩定，不(bu)(bu)會因為(wei)突然斷電(dian)而造(zao)成重物墜落事故，好的(de)(de)永(yong)(yong)(yong)磁(ci)(ci)吸(xi)盤(pan)(pan)也比較安全，至于電(dian)磁(ci)(ci)吸(xi)盤(pan)(pan)，受(shou)電(dian)源穩定性影響較大，不(bu)(bu)好說永(yong)(yong)(yong)磁(ci)(ci)吸(xi)盤(pan)(pan)又名磁(ci)(ci)力吸(xi)盤(pan)(pan)或永(yong)(yong)(yong)磁(ci)(ci)起(qi)重器，是機(ji)械廠(chang)，模具廠(chang)，鍛(duan)造(zao)廠(chang)，煉鋼(gang)廠(chang)，造(zao)船(chuan)廠(chang)等(deng)等(deng)使(shi)用鋼(gang)材場所(suo)的(de)(de)必備搬(ban)(ban)運(yun)工(gong)(gong)具，可以(yi)大大提高塊狀，圓柱狀，板材，不(bu)(bu)規則導磁(ci)(ci)性鋼(gang)鐵材料的(de)(de)搬(ban)(ban)運(yun)效率(lv)。永(yong)(yong)(yong)磁(ci)(ci)吸(xi)盤(pan)(pan)是以(yi)高性能(neng)的(de)(de)稀土材料釹鐵硼(peng)（N>40）為(wei)內核(he)，通過(guo)手扳動吸(xi)盤(pan)(pan)手柄(bing)轉(zhuan)動，從(cong)而改變吸(xi)盤(pan)(pan)內部(bu)釹鐵硼(peng)的(de)(de)磁(ci)(ci)力系(xi)統，達到對需(xu)要搬(ban)(ban)運(yun)的(de)(de)工(gong)(gong)件的(de)(de)吸(xi)持(chi)或釋放。
