電磁式振動盤的工作原理：

振(zhen)動(dong)(dong)盤(pan)是由振(zhen)動(dong)(dong)板(ban)(ban),電(dian)磁鐵,銜(xian)鐵,彈簧片,安(an)裝座,減振(zhen)膠墊組成,利用(yong)(yong)控制器產(chan)生與系(xi)統固有頻率相同的(de)脈沖電(dian)流(liu)使(shi)(shi)電(dian)磁鐵勵(li)磁后,系(xi)統發生共振(zhen),銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)(ban)會快速的(de)拉向(xiang)(xiang)電(dian)磁鐵,因為(wei)下降(jiang)速度(du)很快,所(suo)以(yi)物料會浮(fu)在空(kong)中(zhong),并在重力作用(yong)(yong)下落向(xiang)(xiang)料盤(pan),接著在彈簧片的(de)作用(yong)(yong)下,銜(xian)鐵及振(zhen)動(dong)(dong)板(ban)(ban)又被推回(hui),這時使(shi)(shi)料盤(pan)內(nei)的(de)物料向(xiang)(xiang)前方移動(dong)(dong),該(gai)作用(yong)(yong)以(yi)每分鐘3000---10000次(ci)或更高的(de)次(ci)數(shu)反復進行(xing),使(shi)(shi)用(yong)(yong)權料盤(pan)內(nei)的(de)物料平滑(hua)移動(dong)(dong).

交流電(dian)壓(ya)使(shi)電(dian)磁(ci)鐵(tie)產(chan)生磁(ci)場(chang),由于頻率很高,故產(chan)生的(de)磁(ci)力也是瞬間變化的(de),底盤下面(mian)有3---6組一定的(de)角(jiao)度彈簧(huang)(huang)片,當電(dian)磁(ci)鐵(tie)同交流電(dian)瞬間產(chan)生磁(ci)場(chang),彈簧(huang)(huang)片受壓(ya),當電(dian)壓(ya)正弦(xian)波變化的(de)時候,彈簧(huang)(huang)片彈回來(lai),就產(chan)生了力.
