電磁式振動盤的工作原理：

振(zhen)(zhen)動(dong)(dong)(dong)(dong)盤(pan)是由振(zhen)(zhen)動(dong)(dong)(dong)(dong)板(ban),電(dian)(dian)磁(ci)(ci)鐵,銜鐵,彈(dan)簧片,安裝座,減振(zhen)(zhen)膠墊(dian)組成,利用(yong)(yong)控制器產生與系(xi)統固有頻(pin)率(lv)相同的(de)脈沖電(dian)(dian)流使(shi)電(dian)(dian)磁(ci)(ci)鐵勵磁(ci)(ci)后,系(xi)統發生共振(zhen)(zhen),銜鐵及振(zhen)(zhen)動(dong)(dong)(dong)(dong)板(ban)會快速的(de)拉(la)向電(dian)(dian)磁(ci)(ci)鐵,因為下(xia)降速度(du)很(hen)快,所(suo)以物料會浮(fu)在(zai)(zai)空中,并在(zai)(zai)重力作(zuo)用(yong)(yong)下(xia)落向料盤(pan),接著在(zai)(zai)彈(dan)簧片的(de)作(zuo)用(yong)(yong)下(xia),銜鐵及振(zhen)(zhen)動(dong)(dong)(dong)(dong)板(ban)又被推回,這(zhe)時使(shi)料盤(pan)內(nei)的(de)物料向前(qian)方移動(dong)(dong)(dong)(dong),該作(zuo)用(yong)(yong)以每分鐘3000---10000次或更高(gao)的(de)次數反復進行,使(shi)用(yong)(yong)權料盤(pan)內(nei)的(de)物料平滑移動(dong)(dong)(dong)(dong).

交流(liu)電(dian)壓(ya)使電(dian)磁鐵產生(sheng)磁場,由于(yu)頻率很高,故產生(sheng)的(de)磁力也是瞬間(jian)變化(hua)的(de),底盤下面有(you)3---6組一定(ding)的(de)角度彈簧片,當電(dian)磁鐵同交流(liu)電(dian)瞬間(jian)產生(sheng)磁場,彈簧片受壓(ya),當電(dian)壓(ya)正弦波變化(hua)的(de)時候,彈簧片彈回(hui)來,就產生(sheng)了力.
