電磁式振動盤的工作原理：

振動(dong)(dong)(dong)盤(pan)(pan)是由振動(dong)(dong)(dong)板,電(dian)磁(ci)鐵,銜(xian)鐵,彈簧片(pian),安(an)裝座,減(jian)振膠墊組(zu)成(cheng),利用控制(zhi)器產生與系統(tong)固有頻率相(xiang)同的脈沖電(dian)流使電(dian)磁(ci)鐵勵(li)磁(ci)后,系統(tong)發生共振,銜(xian)鐵及(ji)(ji)振動(dong)(dong)(dong)板會快(kuai)速(su)的拉向電(dian)磁(ci)鐵,因為下降速(su)度很(hen)快(kuai),所以物(wu)料會浮在空中(zhong),并在重力作(zuo)(zuo)(zuo)用下落向料盤(pan)(pan),接著在彈簧片(pian)的作(zuo)(zuo)(zuo)用下,銜(xian)鐵及(ji)(ji)振動(dong)(dong)(dong)板又被(bei)推回(hui),這時使料盤(pan)(pan)內的物(wu)料向前(qian)方(fang)移(yi)(yi)動(dong)(dong)(dong),該作(zuo)(zuo)(zuo)用以每分鐘3000---10000次或更高的次數反(fan)復進行,使用權料盤(pan)(pan)內的物(wu)料平(ping)滑移(yi)(yi)動(dong)(dong)(dong).

交流(liu)電(dian)(dian)(dian)壓(ya)使(shi)電(dian)(dian)(dian)磁鐵產生磁場(chang)(chang),由于頻率(lv)很高,故產生的磁力(li)也是瞬(shun)間變化的,底盤下面有3---6組一定的角度彈(dan)簧(huang)片(pian)(pian)(pian),當電(dian)(dian)(dian)磁鐵同交流(liu)電(dian)(dian)(dian)瞬(shun)間產生磁場(chang)(chang),彈(dan)簧(huang)片(pian)(pian)(pian)受壓(ya),當電(dian)(dian)(dian)壓(ya)正弦波變化的時候(hou),彈(dan)簧(huang)片(pian)(pian)(pian)彈(dan)回(hui)來,就產生了(le)力(li).
