電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)(dong)盤是由振(zhen)(zhen)動(dong)(dong)板,電(dian)磁(ci)(ci)鐵,銜鐵,彈簧片(pian),安(an)裝座,減振(zhen)(zhen)膠墊(dian)組成,利(li)用(yong)(yong)(yong)(yong)控制(zhi)器產生(sheng)與(yu)系(xi)統固有頻率相同的(de)脈沖電(dian)流使電(dian)磁(ci)(ci)鐵勵磁(ci)(ci)后(hou),系(xi)統發生(sheng)共振(zhen)(zhen),銜鐵及振(zhen)(zhen)動(dong)(dong)板會(hui)快速(su)的(de)拉(la)向電(dian)磁(ci)(ci)鐵,因為下(xia)降(jiang)速(su)度很快,所以物(wu)料會(hui)浮在(zai)空中,并在(zai)重(zhong)力作用(yong)(yong)(yong)(yong)下(xia)落向料盤,接著在(zai)彈簧片(pian)的(de)作用(yong)(yong)(yong)(yong)下(xia),銜鐵及振(zhen)(zhen)動(dong)(dong)板又(you)被推回,這時使料盤內的(de)物(wu)料向前方移(yi)(yi)動(dong)(dong),該(gai)作用(yong)(yong)(yong)(yong)以每(mei)分鐘(zhong)3000---10000次或更高的(de)次數(shu)反復進行,使用(yong)(yong)(yong)(yong)權料盤內的(de)物(wu)料平滑移(yi)(yi)動(dong)(dong).

交(jiao)流電(dian)(dian)壓(ya)(ya)使電(dian)(dian)磁鐵產生(sheng)磁場(chang),由于頻率很(hen)高,故產生(sheng)的(de)磁力(li)也(ye)是瞬(shun)間變化的(de),底盤(pan)下(xia)面有3---6組(zu)一定(ding)的(de)角度彈簧(huang)片,當電(dian)(dian)磁鐵同交(jiao)流電(dian)(dian)瞬(shun)間產生(sheng)磁場(chang),彈簧(huang)片受壓(ya)(ya),當電(dian)(dian)壓(ya)(ya)正(zheng)弦(xian)波變化的(de)時候,彈簧(huang)片彈回來,就產生(sheng)了(le)力(li).
