電磁式振動盤的工作原理：

振(zhen)動(dong)盤(pan)(pan)是(shi)由(you)振(zhen)動(dong)板,電(dian)磁鐵(tie),銜鐵(tie),彈簧片(pian),安裝座(zuo),減振(zhen)膠墊組成,利用(yong)(yong)控制器產生與系(xi)(xi)統(tong)固有頻率相同的(de)(de)脈(mo)沖電(dian)流使電(dian)磁鐵(tie)勵磁后(hou),系(xi)(xi)統(tong)發(fa)生共振(zhen),銜鐵(tie)及振(zhen)動(dong)板會快速(su)(su)的(de)(de)拉向(xiang)電(dian)磁鐵(tie),因為下(xia)(xia)降速(su)(su)度(du)很快,所以(yi)物(wu)(wu)(wu)料(liao)(liao)(liao)會浮在(zai)空中(zhong),并在(zai)重力作(zuo)(zuo)用(yong)(yong)下(xia)(xia)落(luo)向(xiang)料(liao)(liao)(liao)盤(pan)(pan),接(jie)著在(zai)彈簧片(pian)的(de)(de)作(zuo)(zuo)用(yong)(yong)下(xia)(xia),銜鐵(tie)及振(zhen)動(dong)板又(you)被(bei)推回,這時使料(liao)(liao)(liao)盤(pan)(pan)內的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)向(xiang)前方移動(dong),該作(zuo)(zuo)用(yong)(yong)以(yi)每分鐘3000---10000次或(huo)更高的(de)(de)次數反復(fu)進(jin)行,使用(yong)(yong)權料(liao)(liao)(liao)盤(pan)(pan)內的(de)(de)物(wu)(wu)(wu)料(liao)(liao)(liao)平滑移動(dong).

交流電(dian)(dian)壓使電(dian)(dian)磁(ci)(ci)鐵產(chan)生磁(ci)(ci)場(chang),由于(yu)頻率很高,故產(chan)生的磁(ci)(ci)力(li)也是瞬間變(bian)(bian)化的,底盤下面(mian)有3---6組一(yi)定的角(jiao)度彈(dan)(dan)簧(huang)(huang)片,當電(dian)(dian)磁(ci)(ci)鐵同交流電(dian)(dian)瞬間產(chan)生磁(ci)(ci)場(chang),彈(dan)(dan)簧(huang)(huang)片受壓,當電(dian)(dian)壓正弦波變(bian)(bian)化的時(shi)候,彈(dan)(dan)簧(huang)(huang)片彈(dan)(dan)回來,就產(chan)生了(le)力(li).
